We're starting to see projects _only_ use the SPDX identifiers (and
they're more readable "at a glance" anyway), so it's probably time to
include these...

The next NDK to take these headers only supports API 21 and later, so
clean up some of the trivial cruft.

The clang builtins for arm32 give us identical code to what we had for
sqrt()/sqrtf(), and significantly better (neon) code for
floor()/floorf() than the integer-only implementations we had.

There's potential here to maybe lose some/all of builtins.cpp, but I'll
look at that separately later.

Bug: http://b/157914307
This pragma enables
- -frounding-math, i.e. rounding mode set at runtime are honored
- -ffp-exception-behavior=strict, i.e. FPE semantics are preserved.
- Prevents use of FMA instructions.

Auto-generate NOTICE files for all the directories, and for each one
individually rather than mixing libc and libm together.
Test: N/A
Change-Id: I7e251194a8805c4ca78fcc5675c3321bcd5abf0a
Generate a single NOTICE file rather than one per library. All the
headers come from libc these days anyway.
Test: tools/update_notice.sh
Bug: None

Also clean up some near-miss copyright headers in libm, and remove
some cruft in <grp.h>/<pwd.h> that the script can't automatically
ignore since we stripped all the tabs in those files.
Change-Id: I10796c54dda1ceba87822ae0de26b5d71b54972b
Remove the hand-collated ones, and switch to a script that pulls the
copyright headers out of every file and collects the unique ones.
