<signal.h>/<ucontext.h>: Split those two headers better.
<signal.h> needs only ucontext_t and stack_t from <ucontext.h>. Split
those out to <sys/_ucontext.h> and stop including the full <ucontext.h>
<signal.h>/<ucontext.h>: Split those two headers better.
<signal.h> needs only ucontext_t and stack_t from <ucontext.h>. Split
those out to <sys/_ucontext.h> and stop including the full <ucontext.h>
from <signal.h> and vice versa, for userland.
In <ucontext.h>, continue defining siginfo_t for non-POSIX because
third party code expects us to.
This has been tested with a full dports bulk build.

libc - Fix bugs in getcontext(), setcontext(), and swapcontext()

libc - Fix bugs in getcontext(), setcontext(), and swapcontext()
* Fix multiple bugs revealed by qemu's use of these functions. Most of
these fixes are accomplished by calling sigreturn(uctx) to restore the
state instead of trying to roll our own in userland. This won't be much
slower (if at all) because we had to save and restore the signal state
in the userland code anyway, so we could not avoid making at least one
system call.
Using sigreturn() handles the signal mask atomicy for us so we don't have
to deal with it and fixes numerous other issues. Along with this change,
adjust getcontext() and makecontext() to fill out additional important
fields in the ucontext that sigreturn() inspects.
* Fixes two stack corruption bugs. First, getcontext() was calling
get_mcontext() and get_mcontext() was setting up the setcontext return
state to return 1 ... from get_mcontext(), NOT from getcontext(). If
normal operations or signals mess with the stack, the double return
will not work. Oops.
Secondly, getcontext scribbled over the red-zone in a way that is not
permitted.
* setcontext() was restoring the context as saved by makecontext() or
getcontext(), but setcontext() can also be called with the ucontext
from the signal handler which requires a full restore. setcontext()
was not restoring FPU or scratch registers or rflags.
* Fixes signal restoration bug and corruption that can mess up emulation
in qemu.
* Fixes issues with qemu related to SMP startup and lack of preemption.

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.

rename all of the architecture files and references. This will
