Move the implementation of writing to the system property area
from init to bionic, next to the reader implementation. This
will allow full property testing to be added to bionic tests.
Add new accessor and waiting functions to hide the implementation
from watchprops and various bionic users.
Also hide some of the implementation details of the property area
from init by moving them into _system_properties.h, and other details
from everybody by moving them into system_properties.h.

We were missing SIG_ATOMIC_MAX, SIG_ATOMIC_MIN, SIZE_MAX,
WCHAR_MAX, WCHAR_MIN, WINT_MAX, and WINT_MIN.

Removed 'join_count' from pthread_internal_t and switched to using the flag
PTHREAD_ATTR_FLAG_JOINED to indicate if a thread is being joined. Combined with
a switch to a while loop in pthread_join, this fixes spurious wake-ups but
prevents a thread from being joined multiple times. This is fine for
two reasons:
1) The pthread_join specification allows for undefined behavior when multiple
threads try to join a single thread.
2) There is no thread safe way to allow multiple threads to join a single
thread with the pthread interface. The second thread calling pthread_join
could be pre-empted until the thread is destroyed and its handle reused for
a different thread. Therefore multi-join is always an error.

* A dlmalloc usage error shouldn't call abort(3) because we want to
cause a SIGSEGV by writing the address dlmalloc didn't like to an
address the kernel won't like, so that debuggerd will dump the
memory around the address that upset dlmalloc.
* Switch to the simpler FreeBSD/NetBSD style of registering stdio
cleanup. Hopefully this will let us simplify more of the stdio
implementation.
* Clear the stdio cleanup handler before we abort because of a dlmalloc
corruption error. This fixes the reported bug, where we'd hang inside
dlmalloc because the stdio cleanup reentered dlmalloc.

- Implemented chk_memalign.
- Fixed a few bugs in leak_memalign.
- Implemented {leak,fill,check,qemu}_malloc_usable_size.
- Make malloc_usable_size update at run time.
- Add malloc_test.cpp as a small set of tests for the
malloc debug routines.
- Fix the qemu routines since it's been broken since it moved to C++.
- Add support for the %u format to the out_vformat in libc_logging.cpp.
This is used by the emulator code.
Tested using the bionic-unit-tests with setprop libc.debug.malloc
set to 1, 5, and 10.
I tested as much as possible on the emulator, but tracing doesn't appear
to be working properly.
