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.

A continuation of commit 2825f10b7f61558c264231a536cf3affc0d84204.
Add O_PATH compatibility support for flistxattr(). This allows
a process to list out all the extended attributes associated with
O_PATH file descriptors.

The functions dlmalloc_inspect_all and dlmalloc_trim get
exported on devices that use dlmalloc, so be consistent and
export them everywhere.

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.

It turns out that apportable apps expect that the DIR structure is
the same as in L and below. Modify the structure to have the same
order, and move the new variable to the end of the structure.

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);

GDB does not yet have support for compact branches, and is not able
to set a breakpoint on rtld_db_dlactivity(), which is compiled into
one JIC instruction. Unfortunately, We cannot turn off generation of
JIC compact branch. Instead, add unoptimized FP handling code, so GDB
will have something to land on.
