iOS 10 has <sys/random.h> with getentropy, glibc >= 2.25 has
<sys/random.h> with getentropy and getrandom. (glibc also pollutes
<unistd.h>, but that seems like a bad idea.)
Also, all supported devices now have kernels with the getrandom system
call.
We've had these available internally for a while, but it seems like the
time is ripe to expose them.

GMM calls this system call directly at the moment. That's silly.

We've never really used __restrict: only <string.h> and <stdio.h> (which
are still very similar to upstream BSD headers) consistently have these
annotations. Neither clang nor GCC warns for trivial cases, and there's
little obvious documentation benefit.

This seccomp failure is in the fault handler:
05-25 12:03:25.042 10201 27425 27425 F DEBUG : backtrace:
05-25 12:03:25.042 10201 27425 27425 F DEBUG : #00 pc 00015380
/data/data/redacted/files/storage/lib/libcrashsdk.so
So whenever an app using this crash sdk crashes it looks like a seccomp
problem. Fixing this won't stop the apps crashing, but will make the
crash reports accurate and useful.
So yes, the bug below is already fixed, but this issue has come back 2
or 3 times with different apps (latest is b/62874867). This change
doesn't fix that crash either, but again it improves the reporting.

fstat64/fstatat64/_flush_cache were accidentally put in SYSCALLS.TXT in:
https://android-review.googlesource.com/#/c/390454/
This patch just moves them to SECCOMP_WHITELIST.TXT because we do not
want stubs accidenatally generated for the mentioned syscalls using
gensyscalls.py script.
This commit does not introduce any functional changes to mips64_policy.cpp.
Test: Run genseccomp.py -> File seccomp/mips64_policy.cpp not changed.
Test: Run gensyscalls.py -> INFO:root:no changes detected!

Add some useful new syscalls that we currently aren't using in bionic,
but might in the future to the seccomp whitelist.

Run pylint on genseccomp.py, test_genseccomp.py
Run test_genseccomp.py
Run new CTS test

Test: Make sure arm, x86, x86_64, mips, mips64 emulators boot
Make sure sailfish still boots
Ran CTS test from
https://android-review.googlesource.com/#/c/348671/3 and it passed
The instructions for how to run mips emulators above worked, but
the CTS tests did not seem to actually run.
