Locking stencil buffers with a NULL format resulted in nullptr being
returned without acquiring the resource lock, while unlocking did
release the lock.

Instead of not releasing it on unlock, we must acquire it on lock
because otherwise the object could get destroyed before draw operations
end and attempt to unlock.

Replace all-makefiles-under makefile-macro with explicitly including
Android.mk(s) from subdirectories that are related to OpenGL and are
only needed by Android builds.

The change are mainly made to the top-level Android.mk and the
src/Android.mk. The other three sub-Android.mk(s) are deprecated and
deleted. Soong compile-time is expected to shorten with no use of
all-makefiles-under macros.

Since the project co-existed with both Android.bp and Android.mk.
The test was performed in absence of Android.bp on oc-mr1-dev branch
against aosp_arm-eng and aosp_arm64-eng targets.

NOTE: Android Pie uses Android.bp only.

Tweak ContextPtr to handle move construction/assignment correctly.
This was overlooked when I made the last minute change to use explicit lock/unlock.

Tweak LockGuard to allow construction from ptr to MutexLock, and behave
correctly if mutex == nullptr. This is required because the locking
machinery for EGL is /outside/ the error generation for bad EGLDisplay.

Add 'Big EGL Lock' around most of the EGL API
