9e1281eaba libc: tests: hook CPUSET(9) test up to the build
Add shims to map NetBSD's API to CPUSET(9). Obviously the invalid input
parts of these tests are relatively useless since we're just testing the
shims that aren't used elsewhere, there's still some amount of value in
the parts testing valid inputs.

ac5f382a9d stand: properly declare subdir deps or .WAIT, do parallel build
buildworld already runs the stand build in parallel[1], so make it easier to
identify ordering issues by properly establishing dependencies or adding
.WAIT where needed.

Everything in stand/ relies on libsa, either directly or indirectly, because
libsa build is where the stand headers get installed and it gets linked in
most places.

Interpreters depend on their libs, machine dirs usually depend on top-level
libs that are getting built and at least one of the interpreter flavors.

For i386, order btx/libi386/libfirewire before everything else using a
big-ol-.WAIT hammer. btx is the most common dependency, but the others are
used sporadically. This seems to be where the race reporting on the mailing
list is- AFAICT, the following sequence is happening:

1.) One of the loaders gets built based on stale btx/btxldr
2.) btx/btxldr gets rebuilt
3.) installworld triggers loader rebuild because btx was rebuilt after

This seems like the most plausible explanation, as they've verified system
time and timestamps.

While we're here, let's switch stand/ over to a completely parallel build so
we can work out these kinds of issues in isolation rather than in the middle
of a larger build.

202aea9c82 arm: tune vmparam.h towards a little more modern
An 8MB max stack size is quite limiting in today's world, and in-fact is
the *default* stack size for almost every other arch (including mips).

Raise the default to 4MB (should be pretty reasonable) and the max to 64MB.
NetBSD made a similar move back in 2015 and raised MAXDSIZ to 1856 at the
same time, so let's just roll that in as well. They later lowered it, but
eventually raised it back to 1856 in order to build rust.

This was noticed while looking at qemu-bsd-user's default stack sizes and
growth behavior (or lack thereof).

c4a0333b55 vt: restore tty when console is ungrabbed
When a break-to-debugger is triggered, kdb will grab the console and vt(4)
will generally switch back to ttyv0. If one issues a continue from the
debugger, then kdb will ungrab the console and the system rolls on.

This change adds a perhaps minor feature: when we're down to grab == 0 and
if vt actually switched away to ttyv0, switch back to the tty it was
previously on before the console was grabbed.

The justification behind this is that a typical flow is to work in
!ttyv0 to avoid console spam while occasionally dropping to ddb to inspect
system state before returning. This could easily enough be tossed behind
a sysctl or something if it's not generally appreciated, but I anticipate
indifference.

be46634337 vt: more carefully handle vt_allocate_keyboard grab work
vt_allocate_keyboard only needs to unwind the effects of keyboard-grabbing,
rather than any associated vt window action that may have also happened.

Split out the bits that do the keyboard work into *_noswitch equivalents,
and use those in keyboard allocation. This will be less error-prone when a
later change will offer up different window state behavior when the console
is ungrabbed.

72cf7db3aa lualoader: add loader_conf_dirs support (loader.conf.d)
loader_conf_dirs is the supporting mechanism for the included
/boot/loader.conf.d directory.  When lualoader finishes processing all of
the loader_conf_files it finds after walking /boot/defaults/loader.conf,
it will now check any and all loader_conf_dirs and process files ending
in ".conf" as if they were a loader.conf.

Note that loader_conf_files may be specified in a loader.conf.d config
file, but loader_conf_dirs may *not*. It will only be processed as specified
in /boot/defaults/loader.conf and any loader_conf_files that were loaded
from there.

282381aa53 rsu: Don't modify read-only firmware block.
The firmware header loaded into an rsu(4) device has to be customized
to reflect device settings.  The driver was overwriting the header
from the shared firmware image before sending it to the device.  If
two devices attached at the same time with different settings, one
device could potentially get a corrupted header.  The recent changes
in a095390344 exposed this bug in the
form of a panic as the firmware blobs are now marked read-only in
object files and mapped read-only by the kernel.

To avoid the bug, change the driver to allocate a copy of the firmware
header on the stack that is initialized before writing it to the
device.

76ff03aef7 powerpc: Fix copyin/copyout race condition
It's possible for a context switch, and CPU migration, to occur between
fetching the PCPU context and extracting the pc_curpcb.  This can cause
the fault handler to be installed for the wrong thread, leading to a
panic in copyin()/copyout().  Since curthread is already in %r13, just
use that directly, as GPRs are migrated, so there is no migration race
risk.

6260bfb087 powerpc: Optimize copyinstr() to avoid repeatedly mapping user strings
Currently copyinstr() uses fubyte() to read each byte from userspace.
However, this means that for each byte, it calls pmap_map_user_ptr() to
map the string into memory.  This is needlessly wasteful, since the
string will rarely ever cross a segment boundary.  Instead, map a
segment at a time, and copy as much from that segment as possible at a
time.

Measured with the HPT pmap on powerpc64, this saves roughly 8% time on
buildkernel, and 5% on buildworld, in wallclock time.

4e4e43dc9e xen: allow limiting the amount of duplicated pending xenstore watches
Xenstore watches received are queued in a list and processed in a
deferred thread. Such queuing was done without any checking, so a
guest could potentially trigger a resource starvation against the
FreeBSD kernel if such kernel is watching any user-controlled xenstore
path.

Allowing limiting the amount of pending events a watch can accumulate
to prevent a remote guest from triggering this resource starvation
issue.

For the PV device backends and frontends this limitation is only
applied to the other end /state node, which is limited to 1 pending
event, the rest of the watched paths can still have unlimited pending
watches because they are either local or controlled by a privileged
domain.

The xenstore user-space device gets special treatment as it's not
possible for the kernel to know whether the paths being watched by
user-space processes are controlled by a guest domain. For this reason
watches set by the xenstore user-space device are limited to 1000
pending events. Note this can be modified using the
max_pending_watch_events sysctl of the device.

This is XSA-349.

916806472a Fix generation of colldef source files for non-UTF-8 locales
- Files for colldef were generated by duplicating UTF-8 collation files
  for each language and included invalid characters in the non-UTF-8
  encodings.  localedef(1) does not allow those characters.
  cldr2def.pl now checks if the characters are valid based on charmap files.

  TODO: ja_JP.UTF-8 locale should not be generated solely from CLDR because
  it was standardized in a document "UI-OSF Application Platform Profile for
  Japanese Environment" which was incompatible with information in CLDR.
  Most of commercial Unix vendors adopt this pre-Unicode-era document
  as the reference even for UTF-8 locale.  Newer versions of Solaris have
  added a CLDR version as ja_JP.UTF-8@cldr, and IBM AIX has used
  JA_JP.UTF-8 for the UI-OSF specification and ja_JP.UTF-8 for CLDR.

  Note that this commit does not change generation of ja_JP.UTF-8.
  Changes related to this issue will be committed separately later.

- Generate POSIX charamap UTF-32 as a reference.  It was confusing that
  charmap.xml used Unicode names defined in UnicodeData.txt though POSIX
  charmap used slightly different names for the same code points.
  cldr2def.pl now uses UTF-32.cm as single information source for Unicode
  symbol names and code points.  Charset.xml is also updated to use them.

- Fix a bug in get_encodings() in cldr2def.pl which did not understand
  0x00+0x00 notation correctly in charmaps/ISCII-DEV.TXT.

- Do not regenerate posix/xx_Comm_C.UTF-8.src every time when doing
  "make build".
