Move open coding of construction of attributes for cut regions and
text cursors to functions so that it is easier to fix and improve.
This commit doesn't fix anything except for removing unnecessary
complications and adding comments.
Switch prison check from PROV_DRIVER to PRIV_KMEM_WRITE (like /dev/mem).
Access to the dri device gives effectively access to the entire memory of the machine (you can program
the graphic card to do DMA).
For current/stable/release this is a NOP, as access to memory is not allowed in a jail. This puts the dri
device into the same (in)security class than /dev/mem for future use.

Add many bitmaps (now there are 13) for mouse cursors and logic to try
to choose the best one.
The old 9x13 cursor was was sort of correct for CGA 640x200 text mode,
but distorted for all other modes. This mode is still available on
all systems with VGA, but stopped being useful in ~1985. It has very
unsquare pixels with an aspect ratio of 240:100 on 4:3 monitors. On
16:9 monitors, the unsquareness in this mode is reduced to only 180:100
iff the monitor stretches the pixels to the full screen.
Newer modes and systems have smaller distortions, but with many more
variations. Square pixels first became common with VGA 640x480 mode
on 4:3 monitors. However, standard VGA text mode also has 9-bit wide
characters and only 25 lines, so it has 720x400 pixels. This has
unsquare pixels with an aspect ratio of 135:100 on 4:3 monitors. On
16:9 monitors, it gives almost-square pixels with an aspect ration of
101:100 iff the monitor stretches, but in modes that were square on
4:3 monitors square similar monitor stretching breaks the squareness.
Guess the physical aspect ratio using heuristics. The old version of
X that I use is further from doing this using info from PnP monitors
that is unavailable in syscons (X doesn't understand if the monitor
is doing stretching and doesn't even understand how its its own mode
changes affect the pixel size). Monitors with aspect ratio control
should be configured to _not_ stretch 4:3 modes to 16:9. Otherwise,
use the machdep.vga_aspect_scale sysctl to compensate. Only 1 of my
4 monitors/laptops requires this. It always stretches to 16:9.
The mouse data has new aspect ratio fields for selecting the best
cursor and a new name field for display in debugging messages.
Selecting the mouse cursor is now a slow operation so it is not done
for every drawing of the cursor. To avoid a new initialization method,
it is done whenever the text cursor is set or changed. Also remove
dead code in settings of text cursors.
Use larger mouse cursors (sometimes the full 10x16 one) for 8x8 fonts
in cases where this works better (mostly in graphics mode).
SYSTEM_COMPILER: Ensure there is not a stale compiler in WORLDTMP.
In a scenario of cross-building it is possible that an OBJDIR's WORLDTMP
contains an older compiler in WORLDTMP/usr/bin/cc that is not rebuilt
if SYSTEM_COMPILER logic is triggered. This compiler was still
incorrectly used. Address this by removing WORLDTMP/usr/bin/cc and all
of the hardlinked files associated with it. Also do this for c++ for
GCC builds.

Add files to help manage the (vga) syscons mouse cursor.
To mostly fix distortion of mouse cursors by non-square pixels, I
needed 8 variants of the same cursor shape for large fonts and
another 7 variants for small fonts. Some variants are shared,
leaving only 13 variants in 26 glyphs altogether. Keep these in
the BDF source file cursor.bdf. cursor.bdf has another 5 unused
experimental cursors in 10 glyphs. cursor.awk is a simple awk
script for converting this and similar bdf files into C declarations
for copying into scvgarndr.c. syscons doesn't use any of this yet.
Fix handling of one more possible exception on return to usermode.
If %ss is loaded with a segment pointing to a non-present descriptor
by the IRETD instruction, a kernel-mode #SS exception is generated.
Resulting T_STKFLT trap must be checked against doreti_iret_fault
location and handled, otherwise userspace may panic the kernel.
Note that this is i386 variant of FreeBSD-SA-15:21.amd64, but unlike
amd64, there is no swapgs on i386 and the issue is arguably not
exploitable.

Fix "mount -uw /" when the filesystem type doesn't match.
This basically makes "mount -uw /" work when the filesystem
mounted on / is NFS, but the one configured in fstab(5) is UFS,
which can happen when you forget to modify fstab.
Note that the whole special case ("else if (argv[0][0] == '/'")
is probably not needed anyway. I'll take a look at removing it
altogether; for now this is a minimally intrusive fix.
After some tests, here are the services that run into a vnet jail:
- defaultroute
- dhclient
- ip6addrctl
- natd
- pf

Correctly ignore branch operators in the top-level parser when applicable.
An oversight in r320742 caused BREs to become sensitive to the branching operator prematurely, which caused
breakage in some limited situations -- namely, those that tried to use branching in a BRE. Most of these scenarios
had already been corrected beforehand to properly use gsed or grep for GNU extensions, so the damage is
slightly mitigated.

Modify the nfsuserd daemon so that it uses an AF_LOCAL socket for upcalls.
This patch modifies the nfsuserd daemon so that it uses an AF_LOCAL socket

The impending libregex will implement GNU extensions to bring BREs and
EREs closer together. Prepare for this and reduce the diff of libregex changes by
refactoring and combining the top-level parsers for EREs/BREs ahead of time.
Branching functionality has been split out to make it easier to follow the combined
version of the top-level parser. It may also be enabled in the parsing context to make
it easier when libregex enables branching for BREs.
A branching context was also added for the various branching functions and so that
BREs, for instance, can determine if they're the first expression in a chain of expressions
within the current branch and treat '*' as ordinary if so.
This should have no functional impact and negligible performance impact.

Add naive benchmark for SSDs in ZFS SLOG role.
ZFS SLOGs have very specific access pattern with many cache flushes,
which none of benchmarks I know can simulate. Since SSD vendors rarely
specify cache flush time, this measurement can be useful to explain why
some ZFS pools are slower then expected. This test writes data chunks
of different size followed by cache flush, alike to what ZFS SLOG does,
and measures average time.
To illustrate, here is result for 6 years old SATA Intel 710 Series SSD:
While the first one obviously has maximal throughput limitations, the
second one has so high cache flush latency (about 2 millisecond), that
it makes one almost useless in SLOG role, despite of its good throughput
numbers. Power loss protection is out of scope of this test, but I
suspect it can be related.
