    android: Change gralloc_handle_t members to be fixed width
    
    In order to lessen future alignment issues, lets switch to
    fixed width integers where possible.
    
    This excludes the data_owner since it is a pid_t which
    in theory could be larger than 32 bits.

    android: Move gralloc handle struct to libdrm
    
    This struct is used in mesa and drm_hwcomposer.
    Versions of if have been implemented in several grallocs:
    drm_gralloc, gbm_gralloc, minigbm and intel-minigbm.
    
    Other than the 1:1 move of the struct a new generic name
    has been chosen and variables have had comments added to them.
