4eb235fb4f Fix bright colors for syscons, and make them work for the first time
for vt.  Restore syscons' rendering of background (bg) brightness as
foreground (fg) blinking and vice versa, and add rendering of blinking
as background brightness to vt.

Bright/saturated is conflated with light/white in the implementation
and in this description.

Bright colors were broken in all cases, but appeared to work in the
only case shown by "vidcontrol show".  A boldness hack was applied
only in 1 layering-violation place (for some syscons sequences) where
it made some cases seem to work but was undone by clearing bold using
ANSI sequences, and more seriously was not undone when setting
ANSI/xterm dark colors so left them bright.  Move this hack to drivers.

The boldness hack is only for fg brightness.  Restore/add a similar hack
for bg brightness rendered as fg blinking and vice versa.  This works
even better for vt, since vt changes the default text mode to give the
more useful bg brightness instead of fg blinking.

The brightness bit in colors was unnecessarily removed by the boldness
hack.  In other cases, it was lost later by teken_256to8().  Use
teken_256to16() to not lose it.  teken_256to8() was intended to be
used for bg colors to allow finer or bg-specific control for the more
difficult reduction to 8; however, since 16 bg colors actually work
on VGA except in syscons text mode and the conversion isn't subtle
enough to significantly in that mode, teken_256to8() is not used now.

There are still bugs, especially in vidcontrol, if bright/blinking
background colors are set.

Restore XOR logic for bold/bright fg in syscons (don't change OR
logic for vt).  Remove broken ifdef on FG_UNDERLINE and its wrong
or missing bit and restore the correct hard-coded bit.  FG_UNDERLINE
is only for mono mode which is not really supported.

Restore XOR logic for blinking/bright bg in syscons (in vt, add
OR logic and render as bright bg).  Remove related broken ifdef
on BG_BLINKING and its missing bit and restore the correct
hard-coded bit.  The same bit means blinking or bright bg depending
on the mode, and we want to ignore the difference everywhere.

Simplify conversions of attributes in syscons.  Don't pretend to
support bold fonts.  Don't support unusual encodings of brightness.
It is as good as possible to map 16 VGA colors to 16 xterm-16
colors.  E.g., VGA brown -> xterm-16 Olive will be converted back
to VGA brown, so we don't need to convert to xterm-256 Brown.  Teken
cons25 compatibility code already does the same, and duplicates some
small tables.  This is mostly for the sc -> te direction.  The other
direction uses teken_256to16() which is too generic.

82b93348db Fix right shifts on arches with db_expr_t larger than u_int (LP64 arches
in practice).

db_expr_t is a signed type, but right shifts are fudged to evaluate
them in an unsigned type, and the unsigned type was broken by hard-
coding it as 'unsigned', so casting to it lost the top bits on arches
with db_expr_t larger than u_int.

The unsigned type with the same size as db_expr_t is not declared;
assume that db_addr_t gives it.  Fixing this properly is less important
than using the correct type for db_expr_t (originally always long for
C90, but always intmax_t since C99).

88521634e9 libc: Use musl's O(n) memmem and strstr
It is O(n) in the length of the haystack (big) string, and has special
cases for short needle (little) strings, of one to four bytes, to avoid
excessive overhead.

There are a small set of nearly trivial cases where the startup overhead
of the musl implementation makes it slightly slower -- for example, a 31
byte needle that matches the beginning of the haystack.  It's faster for
non-trivial cases, and significantly so for inputs that trigger worst-
case behaviour of the previous implementation.  As an example, in my
tests a 16K needle that matches the end of a 64K haystack is nearly
2000x faster with this implementation.

e683c328f8 Introduce 64-bit PowerPC Book-E support
Extend the Book-E pmap to support 64-bit operation.  Much of this was taken from
Juniper's Junos FreeBSD port.  It uses a 3-level page table (page directory
list -- PP2D, page directory, page table), but has gaps in the page directory
list where regions will repeat, due to the design of the PP2D hash (a 20-bit gap
between the two parts of the index).  In practice this may not be a problem
given the expanded address space.  However, an alternative to this would be to
use a 4-level page table, like Linux, and possibly reduce the available address
space; Linux appears to use a 46-bit address space.  Alternatively, a cache of
page directory pointers could be used to keep the overall design as-is, but
remove the gaps in the address space.

This includes a new kernel config for 64-bit QorIQ SoCs, based on MPC85XX, with
the following notes:
* The DPAA driver has not yet been ported to 64-bit so is not included in the
  kernel config.
* This has been tested on the AmigaOne X5000, using a MD_ROOT compiled in
  (total size kernel+mdroot must be under 64MB).
* This can run both 32-bit and 64-bit processes, and has even been tested to run
  a 32-bit init with 64-bit children.

Many thanks to stevek and marcel for getting Juniper's FreeBSD patches open
sourced to be used here, and to stevek for reviewing, and providing some
historical contexts on quirks of the code.

ff17a6773e Don't access the reserved registers %dr4 and %dr5 on i386.
On the original i386, %dr[4-5] were unimplemented but not very clearly
reserved, so debuggers read them to print them.  i386 was still doing
this.

On the original athlon64, %dr[4-5] are documented as reserved but are
aliased to %dr[6-7] unless CR4_DE is set, when accessing them traps.

On 2 of my systems, accessing %dr[4-5] trapped sometimes.  On my Haswell
system, the apparent randomness was because the boot CPU starts with
CR4_DE set while all other CPUs start with CR4_DE clear.  FreeBSD
doesn't support the data breakpoints enabled by CR4_DE and it never
changes this flag, so the flag remains different across CPUs and
the behaviour seemed inconsistent except while booting when the CPU
doesn't change.

The invalid accesses broke:
- read access for printing the registers in ddb "show watches" on CPUs
  with CR4_DE set
- read accesses in fill_dbregs() on CPUs with CR4_DE set.  This didn't
  implement panic(3) since the user case always skipped %dr[4-5].
- write accesses in set_dbregs().  This also didn't affect userland.
  When it didn't trap, the aliasing made it fragile.

Don't print the dummy (zero) values of %dr[4-5] in "show watches" for
i386 or amd64.  Fix style bugs near this printing.

amd64 also has space in the dbregs struct for the reserved %dr[8-15]
and already didn't print the dummy values for these, and never accessed
any of the 10 reserved debug registers.

Remove cpufuncs for making the invalid accesses.  Even amd64 had these.

72dec0792a - Add support for eMMC "partitions". Besides the user data area, i. e.
the default partition, eMMC v4.41 and later devices can additionally
  provide up to:
  1 enhanced user data area partition
  2 boot partitions
  1 RPMB (Replay Protected Memory Block) partition
  4 general purpose partitions (optionally with a enhanced or extended
    attribute)

  Of these "partitions", only the enhanced user data area one actually
  slices the user data area partition and, thus, gets handled with the
  help of geom_flashmap(4). The other types of partitions have address
  space independent from the default partition and need to be switched
  to via CMD6 (SWITCH), i. e. constitute a set of additional "disks".

  The second kind of these "partitions" doesn't fit that well into the
  design of mmc(4) and mmcsd(4). I've decided to let mmcsd(4) hook all
  of these "partitions" up as disk(9)'s (except for the RPMB partition
  as it didn't seem to make much sense to be able to put a file-system
  there and may require authentication; therefore, RPMB partitions are
  solely accessible via the newly added IOCTL interface currently; see
  also below). This approach for one resulted in cleaner code. Second,
  it retains the notion of mmcsd(4) children corresponding to a single
  physical device each. With the addition of some layering violations,
  it also would have been possible for mmc(4) to add separate mmcsd(4)
  instances with one disk each for all of these "partitions", however.
  Still, both mmc(4) and mmcsd(4) share some common code now e. g. for
  issuing CMD6, which has been factored out into mmc_subr.c.

  Besides simply subdividing eMMC devices, some Intel NUCs having UEFI
  code in the boot partitions etc., another use case for the partition
  support is the activation of pseudo-SLC mode, which manufacturers of
  eMMC chips typically associate with the enhanced user data area and/
  or the enhanced attribute of general purpose partitions.

  CAVEAT EMPTOR: Partitioning eMMC devices is a one-time operation.

- Now that properly issuing CMD6 is crucial (so data isn't written to
  the wrong partition for example), make a step into the direction of
  correctly handling the timeout for these commands in the MMC layer.
  Also, do a SEND_STATUS when CMD6 is invoked with an R1B response as
  recommended by relevant specifications. However, quite some work is
  left to be done in this regard; all other R1B-type commands done by
  the MMC layer also should be followed by a SEND_STATUS (CMD13), the
  erase timeout calculations/handling as documented in specifications
  are entirely ignored so far, the MMC layer doesn't provide timeouts
  applicable up to the bridge drivers and at least sdhci(4) currently
  is hardcoding 1 s as timeout for all command types unconditionally.
  Let alone already available return codes often not being checked in
  the MMC layer ...

- Add an IOCTL interface to mmcsd(4); this is sufficiently compatible
  with Linux so that the GNU mmc-utils can be ported to and used with
  FreeBSD (note that due to the remaining deficiencies outlined above
  SANITIZE operations issued by/with `mmc` currently most likely will
  fail). These latter will be added to ports as sysutils/mmc-utils in
  a bit. Among others, the `mmc` tool of the GNU mmc-utils allows for
  partitioning eMMC devices (tested working).

- For devices following the eMMC specification v4.41 or later, year 0
  is 2013 rather than 1997; so correct this for assembling the device
  ID string properly.

- Let mmcsd.ko depend on mmc.ko. Additionally, bump MMC_VERSION as at
  least for some of the above a matching pair is required.

- In the ACPI front-end of sdhci(4) describe the Intel eMMC and SDXC
  controllers as such in order to match the PCI one.
  Additionally, in the entry for the 80860F14 SDXC controller remove
  the eMMC-only SDHCI_QUIRK_INTEL_POWER_UP_RESET.

2610c9f2b2 Add teken_256to16() to convert xterm-256 256-color codes to xterm 16-color
codes.  This will be used to fix bright colors.

Improve teken_256to8().  Use a lookup table instead of calculations.  The
calculations were inaccurate since they used indexes into the xterm-256
6x6x6 color map instead of actual xterm colors.  Also, change the threshold
for converting to a primary color: require the primary's component to be
2 or more higher instead of just higher.  This affects about 1/5 of the
table entries and gives uniformly distributed colors in the 6x6x6 submap
except for greys (35 entries each for red, green, blue, cyan, brown and
magenta, instead of approx. only 15 each for the mixed colors).  Even
more mixed colors would be better for matching colors, but uniform
distribution is best for preserving contrast.

For teken_256to16(), bright colors are just the ones with luminosity >=
60%.  These are actually light colors (more white instead of more
saturation), while xterm bright colors except for white itself are
actually saturated with no white, so have luminosity only 50%.

These functions are layering violations.  teken cannot do correct
conversions since it shouldn't know the color maps of anything except
xterm.  Translating through xterm-16 colors loses information.  This
gives bugs like xterm-256 near-brown -> xterm-16 red -> VGA red.

b4d3325975 Don't clear p_ptevents on normal SIGKILL delivery
The ptrace() user has the option of discarding the signal. In such a
case, p_ptevents should not be modified. If the ptrace() user decides to
send a SIGKILL, ptevents will be cleared in ptracestop(). procfs events
do not have the capability to discard the signal, so continue to clear
the mask in that case.

b91aad35da loader: remove open_disk cache
As we provide the disk size verification and correction via disk_ioctl
and disk state provided by disk_open(), we can not share the partition
state in disk_devdesc structure. Also the sharing does make a lot of sense
with ufs, as only one partition is open at any given time, but zfs pools
do keep the disk devices open.

To make sure we do get the correct information about the open device,
just remove the cache.
