The arch variant of genrule.out will be soon disallowed in soong.

Test: Manually build.

Pull the portable C string functions from FreeBSD, and do fairly literal
translations of our existing .S files for the bionic-specific stuff.

These are sufficiently intertwined that they need to be done together.
riscv64 is our first primary-only architecture, so that required some
changes. The .bp changes are to support this --- we need to only show
the python scripts the architectures they'll actually be using, rather
than showing them everything and ignoring some of the results.
riscv64 is also the first architecture that post-dates the kernel's
64-bit time work, so there's a bit of extra fiddling needed to handle
the __NR3264_ indirection in the uapi headers.

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.

In particular, explain why we don't have process_mremove(), and why
adding this was probably a mistake (lest it be used as precedent for
similar bad decisions in future).
Also add the missing __INTRODUCED_IN().
