Add symmetric heap add/remove APIs and export symbols from
ion core that are needed to make both heaps modular.

Now that we know the APIs needed by system and cma heaps,
refactor and move all those into linux/ion.h.
Unfortunately, the UAPI of ion is now split into linux/ion.h
and drivers/staging/android/uapi/ion.h since some of the UAPI
leaks into heap implementation (ion flags). It can all be moved
into linux/ion.h eventually for all android kernels.

This patch is preparatory work for making ion heaps modular. The patch
itself doesn't make any significant changes except for re-organizing the
buffer manipulator functions in a single file. This will be helpful
later when we specifically export some of these functions to be used by
a heap module.

Expose ion_alloc() to kernel space clients. Users of this
function will receive a dma-buf structure for sharing
the ION buffer that was allocated.
