The shared memory buffer used by srcPtr can be freed by another
thread because it is not protected by a mutex. Subsequently,
a use after free AIGABRT can occur in a race condition.
SafetyNet logging is not added to avoid log spamming. The
mutex lock is called to setup for decryption, which is
called frequently.
The crash was reproduced on the device before the fix.
Verified the test passes after the fix.

This caused b/38343526 which is a chase list issue, reverting for now.
This reverts commit 4e1fe736af.

The initial drm hidl hal implementation assumed one
codec per crypto instance, but in fact there can be
multiple codecs per crypto instance. This change
extends the drm hal to allow multiple memory heaps
per crypto plugin. It fixes the issue of mapping
memory frequently during playback.

Previously the drm and crypto plugins were separate hals.
This implied a separation of implementation libraries which
causes problems for some drm schemes. The reorganization
combines the hals into a single interface under drm.
Tests: basic gtests passing
