tcp_output.c was using a route on the stack for IPv6, which does not
allow route caching or LLE/ndp caching. Switch to using the route
(v6 flavor) in the in_pcb, which was already present, which caches
both L3 and L2 lookups.

clang is now inserting .file directives with the entire path in
them. This is fine, except that our sed peephole optimizer removes
them if ${SRCTOP} or ${OBJTOP} contains 'align' or 'nop', leading to
build failures. The sed peephole optimizer removes useful things for
boot2 when used with clang, so restrict its use to gcc. Also, gcc no
longer generates nops to pad things, so there's no point in removing
it. Specialize the optimization to just removing the .align 4 lines to
preclude inadvertant path matching.

This, like including ucl private headers, is useful for writing new base

The funcs are declared k&r style, where the args are not specified:
void xuio_stat_wbuf_copied();
They should be declared to take no arguments:
void xuio_stat_wbuf_copied(void);
Need to change both .c and .h.

- Don't execute any of g_mirror_shutdown_post_sync() when panicking. We
cannot safely idle the mirror or stop synchronization in that state, and
the current attempts to do so complicate debugging of gmirror itself.
- Check for a non-NULL panicstr instead of using SCHEDULER_STOPPED(). The
latter was added for use in the locking primitives.

GNU libtool checks the output from invoking the linker with --version
and --help, in order to determine the linker "flavour" and the command-
ine arguments to use for various link operations (e.g. generating shared
libraries). To detect GNU ld it looks for the strings "GNU" and
"supported targets:.*elf". Since LLD is compatible with GNU ld we
include those same strings to fool libtool.
Quoting from a comment in the change:
This is somewhat ugly hack, but in reality, we had no choice other
than doing this. Considering the very long release cycle of Libtool,
it is not easy to improve it to recognize LLD as a GNU compatible
linker in a timely manner. Even if we can make it, there are still a
lot of "configure" scripts out there that are generated by old
version of Libtool. We cannot convince every software developer to
migrate to the latest version and re-generate scripts. So we have
this hack.

The change introduced a dependency between genassym.c and header files
generated from .m files, but that dependency is not specified in the
make files.
Also, the change could be not as useful as I thought it was.
Reported by: dchagin, Manfred Antar <null@pozo.com>, and many others
that used to work via the bold hack).
Fix the table entry for bright black. Fix spelling of plain black in
nearby table entries (use the macro for black everywhere everywhere).
Fix the currently-unused non-bright color table to not have bright
colors in entries 9-15.
Improve nearby comments. Start converting to the xterm terminology
and default rendering of "bright" instead of "light" for bright
colors.
Syscons wasn't affected by the bug since I optimized it a little by
converting colors 0-15 directly. This also fixes the layering of
the conversion for these colors.
Apply the same optimization to vt (actually the layer above it). This
also moves the conversion 1 closer to the correct layer for colors
0-15.
The optimization of just avoiding 2 calls to a trivial function is worth
about 10% for simple output to the virtual buffer with occasional
rendering. The optimization is so large because the 2 calls are done
on every character, so although there are too many other calls and
other instructions per character, there are only about 10 times as
many. Old versions of syscons were about 10 times faster for simple
output, by using a fast path with about 12 instructions per character.
Rendering to even slow hardware takes relatively little time provided
it is rarely actually done.
database in the kernel audit implementation, similar the exist
class mapping database. This will be used by the DTrace audit
provider to map audit event identifiers originating in the
system-call table back into strings for the purposes of setting
probe names. The database is initialised and maintained by
auditd(8), which reads values in from the audit_events
configuration file, and then manages them using the A_GETEVENT
and A_SETEVENT auditon(2) operations.

- Add a new "qsize" parameter in audit_control and the getacqsize(3) API to
query it, allowing to set the kernel's maximum audit queue length.
- Add support to push a mapping between audit event names and event numbers
into the kernel (where supported) using new A_GETEVENT and A_SETEVENT
auditon(2) operations.
- Add audit event identifiers for a number of new (and not-so-new) FreeBSD
system calls including those for asynchronous I/O, thread management, SCTP,
jails, multi-FIB support, and misc. POSIX interfaces such as
posix_fallocate(2) and posix_fadvise(2).
- On operating systems supporting Capsicum, auditreduce(1) and praudit(1) now
run sandboxed.
- Empty "flags" and "naflags" fields are now permitted in audit_control(5).
Many thanks to Christian Brueffer for producing the OpenBSM release and
importing/tagging it in the vendor branch. This release will allow improved
auditing of a range of new FreeBSD functionality, as well as non-traditional

mode (-mthumb, -marm), it reflect's capability of given CPU.
Due to this:
- use __tbumb__ and __thumb2__ insteand of __ARM_ARCH_ISA_THUMB
- use '.thumb' directive consistently in all affected files
- decorate all thumb functions using
DEFINE_COMPILERRT_THUMB_FUNCTION()
