libmemtrack: avoid counting surfaceflinger buffers twice
The system wide Graphics memory usage is inaccurate because some ION
buffers which are shared between processes are counted twice, once for
the buffer's consumer (surfaceflinger), and again for the producer.
These ION buffers appear in surfaceflinger's kgsl memory dump with
usage=egl_image, and in the producer's dump with usage=egl_surface.
Improve the accuracy of Graphics memory tracking by ignoring all ION
buffers with usage=egl_image in the surfaceflinger process, under the
assumption that the buffers will be accounted for when examining the
producer's process.

msm8084: libmemtrack: Use kgsl memory flag to determine usermapped buffers
Instead of using useraddr from kgsl memory allocations to be
matched against proc/<pid>/smaps file to be used to determine
usermapping of a buffer, use the newly added flag which directly
indicates whether a given gpubuffer entry is usermapped or
not. The flag is the last character in the "flags" field.

Initial msm8x64 memory tracker HAL
Reads memory info from kgsl to track unaccounted for GL and ION
memory. Right now it has to parse every allocation and then
cross-reference it against /proc/pid/smaps. It would be faster
to modify the kgsl driver to keep counters that could just be
read directly.
