02c78a3867 Reimplement isinf/isnan/fpclassify.
Also move isinf and isnan into libc like everyone else.

Also move fpclassify to libc like the BSDs (but unlike glibc). We need
this to be able to upgrade our float/double/long double parsing to gdtoa.

Also add some missing aliases. We now have all of:

  isnan, __isnan, isnanf, __isnanf, isnanl, __isnanl,
  isinf, __isinf, isinff, __isinff, isinfl, __isinfl,
  __fpclassify, __fpclassifyd, __fpclassifyf, __fpclassifyl.

4d77c1151c Fix LP64 libm for 128-bit long doubles
* reworked amd64/_fpmath.h and arm64/_fpmath.h to support 128-bit long
doubles.
* improved tests to cover long double cases
* made modfl an alias for LP32

Tests pass on x86, x86_64, arm, arm64 and mips.

ab61eb366a Switch to upstream sleep(3) and usleep(3).
Also fix the signature of usleep, and the definition of useconds_t which
should be unsigned, as the 'u' in its name implies.

This patch also cleans up the existing FreeBSD hacks by moving the libm
stuff from <sys/cdefs.h> to a libm-private header, and adding comments
about the hacks we use to build FreeBSD source.

ad59322ae4 Pull the pthread_key_t functions out of pthread.c.
This was originally motivated by noticing that we were setting the
wrong bits for the well-known tls entries. That was a harmless bug
because none of the well-known tls entries has a destructor, but
it's best not to leave land mines lying around.

Also add some missing POSIX constants, a new test, and fix
pthread_key_create's return value when we hit the limit.

a0ee07829a Upgrade libm.
This brings us up to date with FreeBSD HEAD, fixes various bugs, unifies
the set of functions we support on ARM, MIPS, and x86, fixes "long double",
adds ISO C99 support, and adds basic unit tests.

It turns out that our "long double" functions have always been broken
for non-normal numbers. This patch fixes that by not using the upstream
implementations and just forwarding to the regular "double" implementation
instead (since "long double" on Android is just "double" anyway, which is
what BSD doesn't support).

All the tests pass on ARM, MIPS, and x86, plus glibc on x86-64.
