Cherry pick bionic 86d2feef9f4df517dd5755b39b993bec0c3e1ea5 which
fixes struct stat64. This may look like breaking mips64 ABI, but mips64
support is stil work in progress post-L

This CL unconditionally removes the existance of __builtin_isinf and
__builtin_isnan from math.h for clang, because (unlike other math functions)
clang doesn't like those to be declared.
See LLVM bugzilla entry: http://llvm.org/bugs/show_bug.cgi?id=20958
The reason for decorating all math functions with __attribute__((pcs("aapcs")))
is to offer developers the ability to compile their code with hardfp and still
link Android's libm.so which follows softfp calling convention.
Before issue 20958 is fixed, those who want clang to compile their code with
hardfp in NDK has to go all the way hard, ie.
1) LOCAL_CFLAGS += -mhard-float -D_NDK_MATH_NO_SOFTFP=1
Note that _NDK_MATH_NO_SOFTFP=1 remove __attribute__((pcs("aapcs"))) for all math functions
2) LOCAL_LDLIBS += -lm_hard # link libm_hard.a recompiled with -mhard-float instead of bionic libm.so

When defined as char pointers, every compilation unit that includes
the NdkMediaDrm.h header defines a new copy of the same global
variables - leading to linker errors due to multiple definitions
if more than one file includes it.
By using a define, they don't generate any symbols. The NdkMediaFormat.h
header uses extern const char* for a similar set of keys, but that
can't be added after the actual platform has shipped. The other
alternative would be to declare them as static const char*, which
wouldn't generate global symbols, but which could trigger warnings
about unused static symbols instead.
The same change has already been applied in frameworks/av in
https://android-review.googlesource.com/120303.

1. move sgidefs.h to libc/arch-mips.
See bionic 6e50cb454451916ced315680f6c13dc08cf3959a
2. change type of u_ar0 from "unsigned long" to "struct user_regs_struct*".
See bionic e03950fa0c5567edf70d011b856a027e03b1c0f7
3. sync fts.h, dlext.h, sys/user.h
4. remove ' from string.h

The common header include/linux/a.out.h include asm/a.out.h, but
arm64/mips/mips64 don't have it. Add a placeholder before bionic
has it
