Remove some legacy declarations from <math.h>.
These are still needed for backwards compatibility with code built by old
versions of the NDK, but we don't need to pollute the headers with them.
Also lose the hand-written code for these. The compiler-generated code
is either the same or better, and no new code is calling these functions
anyway.

Use __RENAME for long double functions.
We can cut a lot of stuff out of the NDK's libandroid_support with this,
and reduce unnecessary relocations for all LP32 code. LP64 code should
be unaffected.

Revert "isnan and isinf aren't functions."
While this change is correct, GNU libstdc++ 4.9 isn't able to handle a
standard compliant C library. Its <cmath> will `#undef isnan` from
math.h and only adds the function overloads to the std namespace,
making it impossible to use both <cmath> (which gets included by a
lot of other standard headers) and ::isnan.
We're going to have to revert this until we can start turning down
support for gnustl.
This reverts commit e76ee993ff30a639d24c7db6a080c14d1b1a10f2.

isnan and isinf aren't functions.
isnan was a function in POSIX in 1997, but changed to a macro only in 2004
to align with the C standard. isinf wasn't in POSIX until 2004, where it
appeared as a macro only (but other C libraries already had it as a
function).
Now the C++ standard has added ::isnan and ::isinf functions with different
signatures from the historical ones, so we need to move our historical cruft
out of the way.
We'll keep the implementations for backwards compatibility.

Rename __pure, __pure2, and __purefunc.
These names were pretty misleading (aka "backwards"), so switch to the
same obvious names glibc uses.

Provide fake definitions for libstdc++.
libstdc++ needs to be able to `using ::foo` these in the various C++
wrapper headers for the C library. The NDK long ago added fake
definitions. We need to keep the same.

Don't expose all BSD extensions.
Just expose the ones that bionic historically leaked.
Also, many of the M_* constants in <math.h> are actually POSIX.

Rationalize visibility.
If it's C or POSIX, it's in. If it's BSD or GNU, it's guarded by __USE_BSD
or __USE_GNU.

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