liblua glues the lua run time into the boot loader. It implements all
the runtime routines that lua expects. In addition, it has a few
standard 'C' headers that nueter various aspects of the LUA build that
are too specific to lua to be in libsa. Many refinements from the
original code to improve implementation and the number of included lua
libraries. Use int64_t for lua_Number. Have "/boot/lua" be the default
module path. Numerous cleanups from the original GSoC project,
including hacking libsa to allow lua to be built with only one change
outside luaconf.h.
Add the final bit of lua glue to bring in liblua and plug into the
multiple interpreter framework, previously committed.
Add LOADER_LUA option, currently off by default.
Presently, this is an experimental option. One must opt-in to using
this by defining WITH_LOADER_LUA and WITHOUT_FORTH. It's been
lightly tested, so keep a backup copy of your old loader handy.
The menu code, coming in the next commit, hasn't been exhaustively
tested. A LUA boot loader is 60k larger than a FORTH one, which is
80k larger than a no-interpreter one. Subtle changes in size
may tip things past some subtle limit (the binary is ~430k now
when built with LUA). A future version may offer coexistance.
Bump FreeBSD version to 1200058 to mark the milestone.

Using args[2]->tcps_state as-documented results in error:
operator -> cannot be applied to pointer to type "void"
This error is accurate as the synopsis for tcp:::state-change is:
tcp:::state-change(void *, csinfo_t *, void *, tcpsinfo_t *, void *,
tcplsinfo_t *);
args[2] refers to the third argument which is always NULL (as-
documented). The to-state for the TCP connection state transition is
actually in the fourth argument, args[3]->tcps_state.
Summary:
r329077 caused gcc to emit uninitialized use warnings. Attempting to
fix those warnings yielded the following warnings:
usr.bin/tftp/main.c: In function 'main':
usr.bin/tftp/main.c:181: warning: variable 'el' might be clobbered by
'longjmp' or 'vfork'
usr.bin/tftp/main.c:182: warning: variable 'hist' might be clobbered by
'longjmp' or 'vfork'
This is a known bug in gcc, found at

Work around that by simply marking hist and el as static.

This is a first part of the change. It makes the drivers to calculate
the required number of chain frames to satisfy worst case scenarios, but
it does not change existing overly strict limits on them. The next step
will be to rewrite the allocator to not require megabytes of physically
contiguous address space, that may be problematic if done after boot,
after doing which the limits can be removed. Until that this code can
just correct user set limits, if they are set too high.

Introduce WITH_/WITHOUT_LLVM_COV to match GCC's WITH_/WITHOUT_GCOV.
It is intended to provide a superset of the interface and functionality
of gcov.
It is enabled by default when building Clang, similarly to gcov and GCC.
This change moves one file in libllvm to be compiled unconditionally.
Previously it was included only when WITH_CLANG_EXTRAS was set, but the
complexity of a new special case for (CLANG_EXTRAS | LLVM_COV) is not
worth avoiding a tiny increase in build time.

r328113 and affecting SMP systems.
The way the time is set on PowerMacs is racy and relies on all the
CPUs in the system setting a register simultaneously in a rendezvous. A
few-cycle delay can result in out-of-sync times, which can break the
scheduler and result in calls like mtx_sleep() and pause() never timing out
if the thread is migrated while sleeping. r328113 added a call to a no-op
function between the beginning of the rendezvous and setting the time that
was only called on APs and added enough cycles to cause a problematic offset.
For some reason, the fan-management code was the first place this appeared.
