This way, callees don't need to worry about whether or not their
reference to __riscv_hwprobe() has been resolved before their ifunc
resolver is called.
This matches the current glibc proposal from rivos.

This works out a bit silly/ugly because the bits/ header file has the
wrong name, so I've also changed the map from kernel struct to boolean
to be a map from kernel struct to filename. That not only fixes this,
it's a bit more readable too. (Just yesterday, when I had no real reason
to change it, I was asking myself "why is this a boolean?"!)

The zygote cannot have visiblity to LIBC_PLATFORM methods. Therefore,
move __system_properties_reload to LIBC, and rename it
__system_properties_zygote_reload, and indicate in comments that it
should not be used by non-zygote apps

When used in an ifunc resolver, errno@plt won't be available. This is
the API the rivos folks contributing to glibc are leaning towards, for
the same reason. Hit by the berberis folks because they don't implement
the syscall so they were trying to set errno to ENOSYS.
Tested by looking at the generated assembler, and also disabling the
vdso (since on actual systems, this will go via the vdso).

I've also added doc comments for everything in <sys/epoll.h>.
I've also broken up the old "smoke" test (which was taking 2s on my
riscv64 qemu) to keep the total runtime for all the tests down to 200ms.

If we're going to need PAGE_SIZE in other places, we don't want the
namespace pollution of pulling in all of <sys/user.h>. (The experimental
support for non-4KiB pages found an existing place -- <pthread.h> --
where we were assuming PAGE_SIZE is already available, as if
<sys/user.h> has already been included, so that was actually an existing
bug.)

When the C flag -D__BIONIC_NO_PAGE_SIZE_MACRO is defined,
the PAGE_SIZE macro won't be used for page size agnostic builds.
Note: Only arm64 architectures support page size agnostic builds.

NDK API review complained about missing nullability annotations (added),
not having a `__riscv` #if guard around this function (added), and not
using `__INTRODUCED_IN(35)`. I haven't done the last of these because
that seems less helpful than the traditional "nothing" meaning "always
available" (since this riscv64-only function will be available from
whatever the first riscv64 API level ends up being).

It is easy to dos the property_service socket, since it will wait for a
complete data packet from one command before moving on to the next one.
To prevent low privilege apps interfering with system and root apps,
add a second property_service socket that only they can use.
However, since writes to properties are not thread-safe, limit use of
this second socket to just sys.powerctl messages. These are the messages
that this security issue is concerned about, and they do not actually
write to the properties, rather they are acted upon immediately.

The obsolete mips header rides again!
The most interesting part of this change is that I've removed the hack
that meant that all system call wrappers starting with `__` defaulted to
being hidden symbols. That's no longer useful given our linker scripts,
and it actively got in the way here because the public libc symbol
actually starts with `__` in glibc, and it would be weird and annoying
for developers if we chose a different name.

This reverts commit 24839a681e.
These fixes for b/262208935 introduced a race condition. We believe the
race is fixed by ag/23879563, but at this point in the release feel that
reverting the fixes and refixing in main is the better solution

This *doesn't* include <ctype.h> because I have a separate change
rewriting that (that's blocked on the upcoming libc++ update).
