MFC r230998,r233792: sh: Use vfork in a few common cases.
This uses vfork() for simple commands and command substitutions containing a single simple command, invoking an external program under certain conditions (no redirections or variable assignments, non-interactive shell, no job control). These restrictions limit the amount of code executed in a vforked child.
Various incarnations of this patch have been shown to bring performance improvements: http://lists.freebsd.org/pipermail/freebsd-hackers/2012-January/037581.html
The use of vfork() can be disabled by setting a variable named SH_DISABLE_VFORK.

sh: Fix duplicate prototypes for builtins.
Have mkbuiltins write the prototypes for the *cmd functions to builtins.h instead of builtins.c and include builtins.h in more .c files instead of duplicating prototypes for *cmd functions in other headers.

sh: Save/restore changed variables in optimized command substitution.
In optimized command substitution, save and restore any variables changed by expansions (${var=value} and $((var=assigned))), instead of trying to determine if an expansion may cause such changes.
If $! is referenced in optimized command substitution, do not cause jobs to be remembered longer.
This fixes $(jobs $!) again, simplifies the man page and shortens the code.

sh: Add \u/\U support (in $'...') for UTF-8.
Because we have no iconv in base, support for other charsets is not possible.
Note that \u/\U are processed using the locale that was active when the shell started. This is necessary to avoid behaviour that depends on the parse/execute split (for example when placing braces around an entire script). Therefore, UTF-8 encoding is implemented manually.

sh: Check readonly status for assignments on regular builtins.
An error message is written, the builtin is not executed, nonzero exit status is returned but the shell does not abort.
This was already checked for special builtins and external commands, with the same consequences except that the shell aborts for special builtins.

sh: Apply locale vars on builtins, recognize LC_MESSAGES as a locale var.
This allows doing things like LC_ALL=C some_builtin to run a builtin under a different locale, just like is possible with external programs. The immediate reason is that this allows making printf(1) a builtin without breaking things like LC_NUMERIC=C printf '%f\n' 1.2
This change also affects special builtins, as even though the assignment is persistent, the export is only to the builtin (unless the variable was already exported).
Note: for this to work for builtins that also exist as external programs such as /bin/test, the setlocale() call must be under #ifndef SHELL. The shell will do the setlocale() calls which may not agree with the environment variables.

Implement the PS4 variable which is defined by the POSIX User Portability Utilities option. Its value is printed at the beginning of the line if tracing (-x) is active. PS4 defaults to the string "+ " which is compatible with the old behaviour to always print "+ ".
We still need to expand variables in PS1, PS2 and PS4.

Better handling of word splitting. Don't record the same region multiple times when performing nested variable expansion, and preserve some quoting information in order to avoid removing apparently empty expansion result.

Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

Merge of 4.4-Lite2 sh source, plus some gcc -Wall cleaning. This is a merge of parallel duplicate work by Steve Price and myself. :-]
There are some changes to the build that are my fault... mkinit.c was trying (poorly) to duplicate some of the work that make(1) is designed to do. The Makefile hackery is my fault too, the depend list was incomplete because of some explicit OBJS+= entries, so mkdep wasn't picking up their source file #includes.
This closes a pile of /bin/sh PR's, but not all of them..
