00c97a06be killall: fix a logic error in names_to_pid(). 
This broke a lot of tests in postsubmit, and even seems to have had the
effect of causing reboots (presumably by accidentally killing init)
which made it quite hard to track down.

Sadly I'm too stupid by this point in the afternoon to come up with the
missing test :-(

c7342f8b72 Block signals in exit_signal() so sigatexit() list isn't re-entered. 
xexit() uses siglongjmp() when not exiting, so should clean itself up.

15d1af8951 xgetrandom: fix macOS build. 
BSD has <sys/random.h> first, but has getentropy() in there. glibc
has getentropy() in addition to getrandom(), but they keep it in
<unistd.h> instead. Since both went in in glibc 2.25 I don't think
this will matter in practice, but if this does cause trouble, we
can have separate getentropy() and getrandom() implementations for
the BSDs versus glibc.

This does mean that the only valid values for `flags` are now 0 or
WARN_ONLY, but that was already effectively true anyway because
GRND_NONBLOCK != O_NONBLOCK so the fallback path was already broken.

6cf4d6d4d1 Switch shadow.h and utmpx.h from compile time probes to __has_include(). 
This does mean "make defconfig" can't automatically drop them out, but
the platforms that don't have this aren't building defconfig anyway.

f564bb3cca Avoid copy_file_range(2) on Android. 
Strictly we could use it if the target API level is high enough,
but that would mean that you couldn't safely run the resulting
binary on an older Android release, and anecdotally I don't think
people are that careful.

The obvious alternative would be to install a signal handler for
SIGSYS so we can probe for copy_file_range(2) at runtime rather
than compile time, but it's not obvious to me that it matters enough?

3625a26006 Switch to C11 noreturn to work around a compiler bug in llvm. 
Elliott said:

Works around a clang bug in the version of clang shipping with Android T
that causes a miscompile in xstdio_create() on x86-64, that oddly only
affects __attribute__((__noreturn__)) and not _Noreturn!

50361a1b07 lib/portability.c: don't assume we have __NR_copy_file_range. 
Android's host tools currently build with glibc from 2012, but even if
we were more up to date (or had already switched to musl for host tools,
which hopefully will be the case by this time next year), it was added
to glibc recently enough to miss the "seven year window".

Fallback to read+write when copy_file_range failed, as both fd_in and fd_out must refer to regular files.
