76615dae93 Provide writer preference option in rwlock.
Previous implementation of rwlock contains four atomic variables, which
is hard to maintain and change. So I make following changes in this CL:

1. Add pending flags in rwlock.state, so we don't need to synchronize
between different atomic variables. Using compare_and_swap operations
on rwlock.state is enough for all state change.

2. Add pending_lock to protect readers/writers waiting and wake up
operations. As waiting/wakeup is not performance critical, using a
lock is easier to maintain.

3. Add writer preference option.

4. Add unit tests for rwlock.

9b82136b98 Add ANDROID_DLEXT_FORCE_LOAD flag
This flag allows to force loading of the library
  in the case when for some reason multiple ELF files
  share the same filename (because the already-loaded
  library has been removed and overwritten, for example).

377243b78c Remove PTHREAD_RECURSIVE_MUTEX_INITIALIZER and PTHREAD_ERRORCHECK_MUTEX_INITIALIZER.
These macros are also not used in glibc. And we should use
PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP
and PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP instead.

1101962447 Fix _PATH_DEFPATH to correspond to the actual default path.
This is currently set in init.rc, but I plan on making init
set PATH to _PATH_DEFPATH and removing the line from init.rc...

eb8b122d67 Add alignment to opaque types.
If there is no alignment forced, then the compiler might put these
structures at any alignment.

c09268a3fe bionic: deprecate _PATH_MEM
/dev/mem (and /dev/kmem) are not enabled in the kernels, and selinux
prevents access and makes it a rule compilation error to enable
access. No code uses the _PATH_MEM macro. Remove definition to
suppress future usage.

68dc20d411 Implement _FILE_OFFSET_BITS (mostly).
I still don't think we can make stdio's fseeko and ftello work, but we can
have everything else, and very few programs use fseeko/ftello (and they can
just refrain from using _FILE_OFFSET_BITS and be no worse off than they are
today).

clang don't support warning attribute. Replacing warning attriubte with
deprecated attribute can achieve the same behavior whether compiled by
gcc or clang.
