As part of this, remove include/unwind.h and switch libthr over to using the installed unwind.h.

So adding the inline keywords in for __open in ifstream and ofstream. That will also make it consistent with __open in basic_filebuf (it seems we added `inline` there before for gcc build as well).

Unwinding leaf function is useful in cases when the backtrace finds a leaf function for example when it caused a signal. This patch also add the support for the DW_CFA_undefined because it marks the end of the frames. Ryan Prichard provided code for the tests.

Bisection has shown that this particular upstream commit causes programs using backtrace(3) on aarch64 to segfault. This affects the lang/rust port, for instance.

This requires a bunch of helper functions in libcompiler_rt.a, to avoid link errors like "undefined symbol: __aarch64_ldadd8_acq_rel". (Note: of course you can use -mno-outline-atomics as a workaround too, but this would negate the potential performance benefit of the faster LSE instructions.) Bump __FreeBSD_version so ports maintainers can easily detect this.

That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next.
