Initial import of binutils 2.22 on the new vendor branch

Future versions of binutils will also reside on this branch rather
than continuing to create new binutils branches for each new version.

Merge branch 'master' of ssh://crater.dragonflybsd.org/repository/git/dragonfly

Sync libc/stdlib with FreeBSD (ignoring jemalloc, pts, and gdtoa):

-Add a64l(), l64a(), and l64a_r() XSI extentions. These functions
convert between a 32-bit integer and a radix-64 ASCII string.

-Replace some syscalls with libc version.

-Remove advertising clause.

-alloca() cannot check if the allocation is valid; mention the
consequences.

-Include some verbage about not calling exit() from functions registered
by atexit().

-Use pthread mutexes where possible instead of libc spinlocks.

-Significantly reduce the memory leak as noted in the BUGS section of
setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.

-Prefer setenv() instead of putenv().

-Convert *env() calls to POSIX:
-unsetenv returns an int.
-putenv takes a char * instead of const char *.
-putenv no longer makes a copy of the input string.
-errno is set appropriately. Exceptions involve bad environ
variable and internal initialization code. These both set errno
to EFAULT.

-Make getopt_long() more GNU compatible and sync up with OpenBSD's
version.

-POSIX clearly states that getsubopt() should be declared in <stdlib.h>
not in <unistd.h>

-Use size_t to avoid overflow when sorting arrays larger than 2 GB in
heapsort() and qsort().

-Add new implementations of insque() and remque() which conform to
IEEE Std 1003.1-2001.

-Add qsort_r() for functions that need to be reentrant.

-Improve radixsort()'s preformance when sorting strings with common
prefixes.

-Use 'uint32_t' instead of 'long' when a 32-bit integer is intended in
random(3).

-Rearrange <stdlib.h> in a more logical order based on visibility.

-Move getsubopt()'s prototype to <stdlib.h> (standards).

-Make an internal _getprogname() that is used only inside
libc. For libc, getprogname(3) is a weak symbol in case a
function of the same name is defined in userland.

Complete Citrus import. Import message catalog implement from
NetBSD. Remove external visible rune interface.

Obtained-from: Project Citrus / NetBSD

Back out switch to getopt_long implementation of getopt, it breaks
too much. This will be done (more carefully) later.

Correctly return -1 for "-" as argument as required by SUS.
Fix a typo where specifying a single invalid short option could
result in an infinite loop.

Use getopt_long's getopt implementation.

Define __DECONST here for the sake of FreeBSD.

Use __DECONST for the linted interface violations.

Correctly reset place in getopt_long_only the next time it is used.
Remove unused retval in getopt wrapper.

Better diagnostic for getopt_long_only.

Fix two small bugs in getopt_long_only handling:
- a short option followed by a long option is parsed as that
(inspired by OpenBSD)
- the place variable has to be reset after long option parsing fa

Add support for getopt_long_only. It allows using long options with a single
dash by prefering them over aggregated short options.

Move the handling of '--' as argument into getopt_internal. Add a parameter
to getopt_internal and getopt_internal_short to activate support for long
options. Disable the special 'W' handling for get

Move the handling of '--' as argument into getopt_internal. Add a parameter
to getopt_internal and getopt_internal_short to activate support for long
options. Disable the special 'W' handling for getopt(). Correctly handle
long option like arguments ('--l') as arguments '-' and 'l'.

Move short option parsing into its own function. Constify the local char *
pointer.

Add getopt_long from NetBSD
