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.

Fix crash, uninitialized-return, and buffer bugs in update check and macOS x86 bridge

Fix crash, uninitialized-return, and buffer bugs in update check and macOS x86 bridge
updateprotocol.cxx: guard XNodeList dereferences so a swallowed
XPathException no longer leaves a null reference to be dereferenced
(crash on malformed/hostile update descriptors); clear the list before
the relnote query so a thrown exception can't leave us iterating the
previous (sources) node list.
cpp2uno.cxx: the queryInterface fast-path guard used 'break', which
exited the switch and skipped the default case, returning an
uninitialized typelib_TypeClass. Guard the block with
'if (bHasHiddenReturn)' instead so control falls through to default and
eRet is always assigned.
updatecheck.cxx (getImageFromFileName): use bitwise '|' instead of
logical '||' when combining osl_Process flags; rewrite the trailing
CR/LF trim so it never reads/writes before the start of the buffer
(e.g. when osl_readFile returns 0 bytes).

these details are not generally available in a public header
of most development environments. So we define them locally.
