28154f5c56 Improve library lookup logic 
Linker tries to open a library even if it can
be found by soname. This only happens if the
library was previously opened under different
target sdk version.

f1c85411a8 Avoid name collision with user_fpsimd_state in <asm/ptrace.h>. 
We don't want to use <asm/ptrace.h> because (a) it'll drag in a bunch of
namespace pollution and (b) the registers should be "long double" for
userspace, not the kernel's uint128s. So just use a slightly different
name for our struct (which matches the traditional names for these structs
anyway).

511cfd9dc8 Allow NULL in pthread_mutex_lock/unlock. 
The pthread_mutex_lock and pthread_mutex_unlock were allowed to
fail silently on L 32 bit devices when passed a NULL. We changed
this to a crash on 32 bit devices, but there are still games that make
these calls and are not likely to be updated. Therefore, once again
allow NULL to be passed in on 32 bit devices.

7a799f2b02 Fix a few libc makefile mishaps. 
These are the problems fixed in this CL:

- The ndk_cruft.cpp file was not compiled for 64 bit.
- Some files where not compiled for libc_bionic.a due to a missing
  patch-up-arch-specific-flags call.
- The libc_bionic_ndk.a patch up call was using bionic src, not
  the bionic_ndk_src_files.
- Move mmap.cpp to the ndk src list where it was before because of
  the above errors.

order, and move the new variable to the end of the structure.

c92f9f8069 libc: Add O_PATH support for fgetxattr / fsetxattr 
Support O_PATH file descriptors when handling fgetxattr and fsetxattr.
This avoids requiring file read access to pull extended attributes.

This is needed to support O_PATH file descriptors when calling
SELinux's fgetfilecon() call. In particular, this allows the querying
and setting of SELinux file context by using something like the following
code:

  int dirfd = open("/path/to/dir", O_DIRECTORY);
  int fd = openat(dirfd, "file", O_PATH | O_NOFOLLOW);
  char *context;
  fgetfilecon(fd, &context);

This change was motivated by a comment in
https://android-review.googlesource.com/#/c/152680/1/toys/posix/ls.c
