Add a DSO (malloc/tst-aligned_alloc-lib.so) that can be used during testing to interpose malloc with a call that randomly uses either aligned_alloc, __libc_malloc, or __libc_calloc in the place of malloc. Use LD_PRELOAD with the DSO to mirror malloc/tst-malloc.c testing as an example in malloc/tst-malloc-random.c. Add malloc/tst-aligned-alloc-random.c as another example that does a number of malloc calls with randomly sized, but limited to 0xffff, requests. The intention is to be able to utilize existing malloc testing to ensure that similar allocation APIs are also exposed to the same rigors. Reviewed-by: DJ Delorie <dj@redhat.com>
