`sanitizer_malloc_introspection_t` and initialize them to zero.
We allow sanitizer implementations to perform different initialization
by defining `COMMON_MALLOC_HAS_EXTRA_INTROSPECTION_INIT` to be `1`
and providing an implementation of `mi_extra_init(...)`.
We use these changes in future patches to implement malloc zone enumeration.

enumerator.
This is done by defining `COMMON_MALLOC_HAS_ZONE_ENUMERATOR` to `1` and
then by providing an implementation of the `mi_enumerator(...)` function.
If a custom implementation isn't desired the macro is set to `0` which
causes a stub version (that fails) to be used.
Currently all Darwin sanitizers that have malloc implementations define
this to be `0` so there is no functionality change.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
Add more standard compliant posix_memalign implementation for LSan and
use corresponding sanitizer's posix_memalign implenetations in allocation
wrappers on Mac.
