6361964381 Use a separate config.h for config like defines.
This allows an easier way to share config parameters between unit tests
and the bionic code.

It also fixes a problem where the 32 bit bionic tests based on glibc, or
the cts list executable did not have the pvalloc,valloc tests.

5ee320dd35 Hides valloc(3)/pvalloc(3) on LP64.
These were removed from POSIX 2004. Hides the header declarations for all
targets, and hides the symbols for LP64.

72bbd42357 Support for jemalloc to replace dlmalloc.
To use jemalloc, add MALLOC_IMPL = jemalloc in a board config file
and you get the new version automatically.

Update the pthread_create_key tests since jemalloc uses a few keys.
Add a new test to verify memalign works as expected.

885f3b9cad Implement malloc_usable_size for debug impls.
- 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.
