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).

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.

Adds a new _internal_ function. Provide a global serial number to
support more efficient private caching algorithms. This allows
to skip re-running the __system_property_find() call on misses until
there is a global change in the properties. This call is a read
barrier, the property data to be read following this call will be
read sequentially and up to date.

gcc 5.1 doesn't define char16_t and char32_t (unless in C++ mode),
causing compile failures.

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.

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).
