afe835d540 Move math headers in with the other headers. 
Keeping them separate is a pain for the NDK, and doesn't help the platform.

fc1fb955b3 Android.bp: Add missing <complex.h> functions. 
Android.bp port of https://android-review.googlesource.com/207658

9ee6adb003 Add missing <complex.h> functions. 
FreeBSD doesn't seem interested in having low-quality implementations of
these functions:

  cacoshl, cacosl, casinhl, casinl, catanhl, catanl, ccoshl, ccosl, cexpl,
  clog, clogf, clogl, cpow, cpowf, cpowl, csinhl, csinl, ctanhl, ctanl.

And they still haven't got round to writing good implementations, so for
now let's just take the NetBSD ones so we have the full set.

a29ed0bbce libm: Use LOCAL_SRC_FILES_EXCLUDE_{arch} 
Instead of adding the used common files to each arch that doesn't
override a file, make the architectures list the files they override.

Also updates the Android.bp file to match the Android.mk file.

fa7752986d Fix arm64 fenv warnings, and make warnings errors. 
Even though the control registers being read/written in fenv.c only
have 32 bits that are used, the instructions take a 64 bit register.
Make sure the inline assembler in the macros use 64 bit values.

Verified that before the change and after the change, the disassembly
is exactly the same.

In addition, add -Werror to the cflags.

f9f4a432ee Revert "Revert "Use compiler builtins for fabs."" 
Don't enable the inlines when building libm itself. Otherwise clang gets
upset by seeing both an inline and a non-inline definition.

This reverts commit c5deb0f883.
