38c37d6705 Work around for libraries without dt_soname 
Applies only for apps targeting sdk version <= 22

Bug: http://b/21565766

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

c4ebe60e1a Fix dlsym(handle_of_main_executable, ...) 
According to man dlopen(3) and posix docs in the case when si is handle
  of the main executable we need to search not only in the executable and its
  dependencies but also in all libraries loaded with RTLD_GLOBAL.

3cec6eca92 [MIPS] Do not use compact branches until GDB supports them 
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.
