Actually, we don't want to reuse the kernel struct ucontext because its
uc_mcontext has the wrong type, which means the fields within that end
up with the wrong names. Add the call site that made that evident, and
update <sys/ucontext.h> appropriately.

Empty, at least for now. The other libcs seem not to have invented types
here, so let's see whether there's really a call for them before we do.

In particular, it contains all the riscv64 definitions we need, and lets
us clear up a lot of our existing ELF headers.
The other two BSDs seem to have errors and/or gaps in their riscv64
constants.

I was going to add riscv64 and define __riscv_xlen to 64 here, but our
"preprocessor" in python can't simpify `MACRO_NAME == 123` expressions
anyway. Rather than add another empty map, remove the other unused maps
and explain why this functionality is still useful as long as the legacy
32-bit ABIs are still with us.

We added this symbol somewhat inconsistently, with arm and x86-64 in one
release and arm64 in another. It doesn't really matter where we add
riscv64 (since there was no riscv64 at either of these now-historical
API levels), so arbitrarily go with the majority.

The alternative would be to define an "lp64" shorthand like we have for
SYSCALLS.TXT, but since this functionality is only used by bionic and
old frameworks code to document historical oddities, it's unclear that
it's worth implementing. We shouldn't ever need architecture-specific
annotations again in future.

Looks like we're not using this any more, so rather than add risc-v,
let's just remove this list.

risc-v doesn't have renameat(2), only renameat2(2). Similar to other
architectures, let's make sure everyone's on the same code path by
having all implementations of renameat() go via renameat2().
I've also moved the existing rename()-in-terms-of-renameat() to be in
terms of renameat2() to cut out the middleman!

When I followed these instructions for risc-v, I mistakenly thought
that the auto-download option was a convenience that would get the
currently-approved headers, not the absolute latest. Make it clearer in
the documentation that this is for experts only, not for production.

adding this was probably a mistake (lest it be used as precedent for
similar bad decisions in future).

At the time I added <stdio_ext.h>, I just added what was on the man
page (which matched glibc), not realizing that musl and glibc had
slightly different functionality in their headers.
The toybox maintainer came up with a legitimate use case for this, for
which there is no portable workaround, so I'm adding it here. I'm not
adding the other functions that are in musl but not glibc for lack of a
motivating use case.

There are many cases where there are no more allocations
when a dump of the record allocs might occur. Move the entries
being written to file in the interrupt handler.
Update the unit tests for this new functionality and add a new
unit test that verifies no allocations occur while the entries
are being written.
Fix the unit tests so that the record allocs files get deleted
properly.
Test: All unit tests pass.
Test: Ran 1000 iterations of unit tests to verify no flakes.

This creates a dependency edge between the ndk_library and its headers,
which should be a no-op in regular Soong builds. This dependency edge
will be used in the Multi-tree project to export the relevant .h files into a well
known location

This turns out to over-export GWP-ASan headers to apexes. This is
unnecessary, GWP-ASan headers should only be referenced by libc
internally and debuggerd.

setjmp() and _setjmp() were already correct, but we'd missed
sigsetjmp(). Found while investigating a toybox timeout(1) failure on
macOS, which doesn't annotate _any_ of these functions.
Also add all the missing doc comments while I'm here.
