Now <utmpx.h> isn't any more useful on Android than <utmp.h> is, but it
is POSIX, and -- importantly -- we can implement it with just a header
file, so code can use it on every existing API level.
macOS does indeed only have the <utmpx.h> functions (although it does
still have the <utmp.h> header!), so potentially portable code might
want <utmpx.h> on Android. (glibc/musl both have both headers.)

If a process is failing due to out of memory, some code calls
android_set_abort_message with a nullptr. Specifically, the libc++
library std::terminate can call do this. In this case, put a
null in the abort message.
Test: Call with nullptr and verify the code does not crash.
Test: Modified crasher to set an abort message and set a null abort
Test: message. Ran both, verified the abort message displays in
Test: first case, and doesn't display in the second case.

Auto-generate NOTICE files for all the directories, and for each one
individually rather than mixing libc and libm together.
