This field is used only once and only for main executable;
no need to carry it around in soinfo structure.

clang depends on memcpy where src and dst are the same to actually
work. Even though this is, technically, undefined behavior,
clang is not going to change. Add a test to verify this assumption
holds true for android devices.

In order to enforce this constraint:
The pointer returned if the allocation succeeds shall be suitably
aligned so that it may be assigned to a pointer to any type of object
and then used to access such an object in the space allocated.
Force all allocations on 32 bit systems to have 8 byte alignment,
and all allocations on 64 bit systems to have 16 byte alignment.
Add a test to verify that the allocator returns the correct alignments.

Add a pthread_atfork handler to malloc_debug to lock the TrackData mutex
during fork and reset it in the child. Ensures that the TrackData is
consistent when forking from a multi-threaded process, and that the
mutex is in a defined state in the child.

Found by passing a bad regular expression to the Google benchmark
code (https://github.com/google/benchmark).

POSIX lets us return null and set errno, but that would be annoying and
surprising.

Since we set both fields to NULL all the time, we can alias the two
fields together on LP32 to provide build-time compatibility.

It turns out we don't have any bugs here, but glibc does. Found while
chasing down a toybox failure I saw on the host, but we may as well
add the test in case we ever screw up here in future.

Small modifications needed to allow compilation with the new headers:
- Manually modify bionic/libc/kernel/uapi/asm-mips/asm/siginfo.h to
remove the uapi from the include.
- PR_XXX defines are now available for mips, so remove the definition
from linker_mips.cpp.

This is a common thing for people to want to do, snprintf requires
a lot of stack for itself, and PTHREAD_STACK_MIN should be usable
for realistic code.
