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.

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.

Use .Fn for functions and macros with parameters.

Use .At, .Bsx, .Fx, .Nx and .Ox

Add a note that getopt_long_only(3) is deprecated.

Sweep-fix man page section order to match mdoc(7), part 2/5.

Note: I haven't touched the few man pages that are still using
the old man(7) macros. They will be converted to mdoc later.

Use getopt_long's getopt implementation.

Add getopt_long from NetBSD
