Introduce hw.nvme.use_nvd tunable. This tunable allows both nvd and
nda to be installed in the kernel, while allowing only one of them to
create devices. This is an all-or-nothing setting, and you can't
change it after boot-time. However, it will allow easier A/B testing.

- Use the title role for column headers.
- Fix a typo in a field name (lpwid -> lwpid).
- Place the fields of different threads in separate containers.
Some C wrappers for x86 instructions do not touch global memory and only act
on their arguments; they can be marked __pure2, aka __const__. Without this
annotation, Clang 3.9.1 is not intelligent enough on its own to grok that
these functions are __const__.

The previous limit of 24 was somewhat restrictive, and with this change
ceil(log2(sizeof(struct pfs_node))) is the same as before in both the ILP32
and LP64 models, so the malloc zone used for allocations of struct pfs_node
is the same as before.

I'm not sure what process sjg@ was using, but using CHECKDIR=${.OBJDIR} with
"make check" on ^/head is the correct thing to do. This unbreaks "make check"
for me (unsandboxed, not using CHECKDIR=${.OBJDIR}).
While here, fix a whitespace nit with LIBADD.

0.8.4:
- void anchor width optimization when we have a custom formatter (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=221130)

- Can't skip anchor formatting in non-display styles
- add test case for {[:/18}
- add upload-xohtml-files to 'make upload'
0.8.3:
- xohtml: Add "-w" option to pull support files from gh_pages
- Add "upload-xohtml-files" target to publish support files in gh_pages/
- add HISTORY/AUTHORS section to man pages
0.8.2:
- xohtml: Add div.units as standard CSS text
- Don't treat values as format strings; they are not
- add "-p" to "mkdir -p build" in setup.sh
- add test case for {U:%%} (from df.c)
- detect end-of-string in '%' and '' escaping
- make xo_simple_field, for common simple cases
- xohtml: nuke "n" in "echo" commands

This was submitted by Rogiel Sulzbach (thank you!) but has a few last-minute
changes by me, mostly where the code interfaces to my still-utterly-deficient
imx6_ccm clocks implementation. So blame me for any mistakes.

debug (cudbg) code, hooked up to the main driver via an ioctl.
The ioctl can be used to collect the chip's internal state in a
compressed dump file. These dumps can be decoded with the "view"
component of cudbg.

My change had good intentions, but the implementation was incorrect:
- printf was returning the number of characters in the format string
plus the NUL, but failed in two regards implementation wise:
-- the pathological case, printf(""), wasn't being handled properly since
the pointer is always incremented, so the value returned would be
off-by-one.
-- printf(3) reports the number of characters printed post-conversion via
vfprintf, etc.
- putchar(3) should return the character printed or EOF, not the number
of characters output to the screen.
My goal in making the change (again) was to increase parity, but as bde
pointed out these are freestanding functions, so they don't have to
conform to libc/POSIX. I argued that the functions should be named
differently since the implementation is different enough to warrant it
and to allow boot2 code to be usable when linked against sys/boot and
libstand and other libraries in base. I have no interest in pushing
this change forward more though, as the original concern I had behind
the change with zfsboottest was resolved in r321849 and r321852. The
next person that updates the toolchain gets to deal with the
inconsistency if it's flagged by a newer compiler.

POSIX equivalents
Both printf and putchar return int, not void.
This will allow code that leverages the libcalls and checks/rely on the
return type to interchangeably between loader code and non-loader
code.

The layout of st_rdev has changed after this commit, and assumptions made
in the NetBSD tests are no longer valid. Change the hardcoded assumed
values to account for the fact that major/minor are now represented by
64 bits as opposed to the less precise legacy precision of 16 bits.

Relnotes: st_rdev layout changed; warning about impact of r321920 to
downstream consumers
- Store the symbol table contents in an anonymous swap-backed object. Have
mmap(/dev/ksyms) map that object, and stop mapping the symbol table into
the calling process in ksyms_open(). Previously we would cache a pointer
to the pmap of the opening process, and mmap(/dev/ksyms) would create a
mapping using the physical address found by a pmap lookup at the initial
mapping address. However, this assumes that the cached pmap is valid,
which may not be the case. [1]
- Remove the ksyms ioctl interface. It appears to have been added to work
around a limitation in libelf that no longer exists; see r321842.
Moreover, the interface is difficult to support and isn't present in
illumos. Since ksyms was added specifically to support lockstat(1), it
is expected that this removal won't have any real impact.
- Simplify ksyms_read() to avoid unnecessary copying.
- Don't call the device handle destructor if we fail to capture a snapshot
of the kernel's symbol table. devfs will do that for us.

"br" or "bridge" where - according to the terminology outlined in
comments of bridge.h and mmcbr_if.m around since their addition in
r163516 - the bus is meant and used instead. Some of these instances
are also rather old, while those in e. g. mmc_subr.c are as new as
r315430 and were caused by choosing mmc_wait_for_request(), i. e. the
one pre-r315430 outliner existing in mmc.c, as template for function
parameters in mmc_subr.c inadvertently. This correction translates to
renaming "brdev" to "busdev" and "mmcbr" to "mmcbus" respectively as
appropriate.
While at it, also rename "reqdev" to just "dev" in mmc_subr.[c,h]
for consistency with was already used in mmm.c pre-r315430, again
modulo mmc_wait_for_request() that is.
- Remove comment lines from bridge.h incorrectly suggesting that there
would be a MMC bridge base class driver.
- Update comments in bridge.h regarding the star topology of SD and SDIO;
since version 3.00 of the SDHCI specification, for eSD and eSDIO bus
topologies are actually possible in form of so called "shared buses"
(in some subcontext later on renamed to "embedded" buses).
as taking a register number, and that would get multiplied by 4 to make
a register address. But the header file that consumers have to reference
this stuff publishes register addresses, not numbers. So now everything
works in terms of register addresses.
Note that the HDMI init code was writing into the wrong register before
this change. Apparently whatever it wrote to was harmless, and apparently
HDMI was working because uboot had set up the right bits.
