This uses the new layout of the upstream repository, which was recently
migrated to GitHub, and converted into a "monorepo". 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.
Update a bunch of Makefile.depend files as
a result of adding Makefile.depend.options files

It turns out that a test of backtrace symbol resolution and formatting
requires symbols. Another option mightt be building with -rdynamic instead,
but this works for now.
Re-enabled skipped CI test, as it should now pass.

Drop portions that are unlit or redundant with llvm-libunwind: builtin.c,
unwind.h, and unwind_arm_ehabi_stub.c.
This code should now work with -fPIE binaries, should we choose to build any
that way.
When backtrace() array is full, signal an error so the underlying
Itanium-style C++ exception handling library (llvm-libunwind) knows to stop
tracing instead of continuing. (It should stop on its own when it finishes
unwinding, so this is mostly an extra seatbelt against an infinite loop bug
in the unwinder.)
This both avoids some dependencies on xinstall.host and allows
bootstrapping on older releases to work due to lack of at least 'install -l'
support.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.
