Naomi Luis 18e73bc5c7 Display: Add libQcomUI
Add libQComUI which is used to perform operations specified by
SurfaceTextures.
The operation currently supported by this library is SET_BUFFER_SIZE
which deallocates and reallocates memory if the size allocated for the
buffer does not match the size requested by the client.
