eae27dc55a Make mips generated assembler more like the mips64 stuff.
I broke the mips build yesterday because it doesn't use
<private/bionic_asm.h> like the other architectures, including mips64.
I want to move mips closer to mips64 to try to avoid this kind of thing
in future.

5f6f4a956c Fix signbit / infinite / isinf / isnan unit tests.
Turns out stlport isn't broken. <cmath> (included
transitively via gtest in our case) is not required
to make C99 math macros (like signbit) available, nor is
it required to preserve them if they're already defined.
It is only required to make the equivalent functions in
namespace std available.

I couldn't find any documentation of required behaviour for
programs that include both <math.h> and <cmath>.

I've verified experimentally that llvm's libc++ and gnu
stl behave the same as stlport.

006f9ad891 Linker writes to wrong memory location when processing DT_MIPS_RLD_MAP
When bionic's dynamic linker processes the .dynamic section of a MIPS ELF binary and encounters the DT_MIPS_RLD_MAP dynamic array tag, it calculates the address of where to write a pointer to the _r_debug structure. The current implementation simply reads the value given in the d_ptr field and writes the pointer address to that location. However, this value has to be adjusted to reflect the real load address of the binary. Otherwise the linker will write to a faulty location possibly resulting in a crash when linking a MIPS binary that includes DT_MIPS_RLD_MAP. This change corrects that problem.

db1ea34748 Implement some of the missing LFS64 support.
This gives us:

* <dirent.h>
  struct dirent64
  readdir64, readdir64_r, alphasort64, scandir64

* <fcntl.h>
  creat64, openat64, open64.

* <sys/stat.h>
  struct stat64
  fstat64, fstatat64, lstat64, stat64.

* <sys/statvfs.h>
  struct statvfs64
  statvfs64, fstatvfs64.

* <sys/vfs.h>
  struct statfs64
  statfs64, fstatfs64.

This also removes some of the incorrect #define hacks we've had in the
past (for stat64, for example, which we promised to clean up way back
in bug 8472078).

Colin Cross
3d19a8319b bionic: fix __set_errno for arm64 syscalls that return a 64-bit value
bionic/libc/arch-arm64/syscalls/read.S ends with:
    b.hi __set_errno
    ret
END(read)

If __set_errno returns int, it will set w0 to 0xFFFFFFFF, which means
x0 is 0x00000000FFFFFFFF.  When interpreted as a ssize_t that is
INT_MAX, not -1.

Change __set_errno to return long, which will cause x0 to be set instead
of w0.

These were needed when bionic's header files were missing these macros (though
it would have made a lot more sense to just fix the header files!) but cause
warnings now.

aa0ebdafc7 Clean up sys_signame and sys_siglist a little.
We don't need quite so much duplication because we already have a way
to get the signal number from its name, and that already copes with the
fact that the mips/mips64 numbers are different from everyone else's.

Also remove sys_signame from LP64. glibc doesn't have this BSD-ism.

f25d677147 Reconfig libc's Android.mk to build for multilib
1. Moved arch-specific setup to their own files:
    - <arch>/<arch>.mk, arch-specific configs. Variables in those config
      end with the arch name.
    - removed the extra complexity introduced by function libc-add-cpu-variant-src,
      which seems to be not very useful these days.
2. Separated out the crt object files generation rules and set up the
   rules for both TARGET_ARCH and TARGET_2ND_ARCH.
3. Build all the libraries for both TARGET_ARCH and TARGET_2ND_ARCH,
  with the arch-specific LOCAL_ variables.

199346a2ab Fix NSIG.
Our sigset_t definition hasn't been tied to our NSIG definition since we
switched to uapi headers, so we can now fix it without breaking the LP32 ABI.
The kernel uapi headers define and use _NSIG, so we need to have our scripts
rename the kernel's definitions out of the way, then we can define _NSIG
and NSIG in terms of the kernel's off-by-one value.
