Tweak our declaration for __cxa_allocate_exception()

Tweak our declaration for __cxa_allocate_exception() so that it matches
the one that sometimes shows up in /usr/include/c++/v1/cxxabi.h. Clang
now treats the subtle differences as an error.

Make robust against __cxa_exception ABI changes

Patch OpenOffice to replace __cxa_get_globals()->caughtExceptions,
which is a pointer to the start of a struct __cxa_exception, with
__cxa_current_primary_exception(), which is a pointer to the end. This
allows struct __cxa_exception to be extended at the start as was
recently done in FreeBSD main and stable/13 on 64-bit architectures.

Recently on FreeBSD main and stable/13 __attribute__((__aligned__)) was
added to struct _Unwind_Exception which changes its size on 32-bit
architectures, and that of __cxa_exception as well. Patch openoffice
to detect this so packages built on 13.0 still work on 13.1.

i126553- Basic merges to clean up the FreeBSD port.

Bring major updates from trunk for the FreeBSD build.
This mainly targets the FreeBSD port that uses external
libraries. The buildbot, using internal components,
requires more changes but I am not planning to bring them
to this branch.

r1591501, r1602791:
Fix for the i386 platform.

r1669457, r1669459:
Make FreeBSD bridges code buildable with clang.

r1669462, r1669465, r1694132:
Fixes for recent gcc and clang.
