Bootstrap flua has some magic now to handle modules by building them in
and discovering them via linker sets. This is slightly cleaner than
always building them in and baking them into loadedlibs for both
bootstrap and system flua.
Adjust the stand build now that these three libs have their own new
homes.

This reverts commit 80ada959004c4386880e47b11618f8abfc2d80e1, because
bootstrap flua is about to get backed out.

This allows us to do things like:
```
local fp = assert(fbsd.exec({"ls", "-l"}, true))
local fpout = assert(fp:stdout())
while true do
local line = fpout:read("l")
if not line then break end
print("Read: " .. line)
end
fp:close()
```
The makeman lua rewrite will use it to capture `make showconfig` output
for processing.

This gives us some way to be able to write to stdin if we want to, or
as a future improvement, will allow us to extract stdout from the
process. The handle is setup to close and waitpid() on close/gc so that
existing users wouldn't necessarily leak for the lifetime of the script
if they weren't adopted to the new model.

Additionally, there's no way to get to the end without a valid
stdin_pipe[1] at the moment, so don't check for it. stdin_pipe[0] is
closed earlier, as the parent shouldn't need the read-side of the pipe.
While we're here, also free the file actions earlier and on error --
they're not necessary once posix_spawnp() has returned.

The posix module is subdivided according to C headers; for instance,
posix.unistd contains routines available from unistd.h, such as
chown(2).
A quirk of our implementation is that each of the modules is a direct
entry in the global table. That is, there is no "posix" table.
Instead, "posix.foo" and "posix.bar.baz" are both top-level tables.
This is surprising and goes against Lua's shorthand of using "." to
access keys in a table. lua-posix also doesn't work this way.
Rework things so that "posix" and "posix.sys" are proper tables.
Existing flua code which uses require() to bind posix submodules to a
name will be unaffected. Code which accesses them directly using
something like _G["posix.sys.utsname"].uname() will be broken, but I
don't think anything like that exists. In particular, it is now
possible to call posix.sys.utsname.uname() without any require
statements.

The implementation of chown() in the posix module handles user and group
names as well as numeric IDs. When resolving names, be sure to use
reentrant lookup functions rather than assuming it's safe to clobber the
internal buffers used by getpwnam() and getgrnam().
Fix some style nits while here.

This matches the interface of lposix, although I do wonder why they went
with execp rather than execvp for the function name here.

The key insight here is that the luaL_check*() and luaL_opt*() functions
will happily take indexes that are larger than the stack top and print a
useful error message.
This means that there is no need to check if too few arguments have been
received prior to checking the types of individual arguments.
This patch also replaces a couple reimplementations of luaL_opt*()
functions with the luaL helpers.

The fnmatch function matches a string against a shell-style filename
pattern. It is a complex function and cannot easily be implenented
using regular expressions. Adding fnmatch to flua increases the amd64
binary by less than 1 KB.

- Provide a sys/md4.h in the cross-build environment to fix bootstrap
of libmd.
- flua now exposes WTRAPPED which isn't incredibly common- make it
conditional, we probably won't be using it in any bootstrap context
any time soon.

unistd:
- _exit
- close
- fork
- getpid
- pipe
- read
- write
libgen:
- basename, dirname
stdlib:
- realpath
These are sufficient for a number of real world scenarios. In our first
application of them, we use the libgen+stdlib additions to grab the
script dir based on argv[0]. The unistd assortment is then used to
outsource a bunch of work to forks and report back to the main process.

This module is bundled into flua, it only provides for now the exec
function. The point of the function is to be able to execute a program
without actually executing a shell.
to use it:
fbsd.exec({"id", "bapt"})

This eliminates a lot of stat() calls that happen when lualoader renders the
menu with the default settings, and greatly speeds up rendering on my
laptop.
ftype is nil if loader/loader.efi hasn't been updated yet, falling back to
lfs.attributes() to test.
This is technically incompatible with lfs, but not in a particularly
terrible way.

FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever
extensions we need for base system operations. We currently support a subset
of lfs and lposix that are used in the rewrite of makesyscall.sh into lua,
added in r354786.
flua is intentionally written such that one can install standard lua and
some set of lua modules from ports and achieve the same effect.
linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added
in. This is similar to what we do in stand/. linit.c has been renamed to
make it clear that this has flua-specific bits.
luaconf has been slightly obfuscated to make extensions more difficult. Part
of the problem is that flua is already hard enough to use as a bootstrap
tool because it's not in PATH- attempting to do extension loading would
require a special bootstrap version of flua with paths changed to protect
the innocent.
src.lua.mk has been added to make it easy for in-tree stuff to find flua,
whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.
