        Android.mk: use LOCAL_COPY_HEADERS to export headers.

        Export necessary header files used by other components for
        Android, such as libva intel-driver, gralloc, hwcomposer, etc.

        android: reuse headers lists, separate libdrm from intel headers

        Rather than having a duplicate copy of the headers list(s),
        reuse the existing one(s). Distinguish that the intel headers
        should be copied when libdrm_intel is used.

        v2 Rename the headers variable(s) to *_H_FILES.

        Export include dir from libdrm

        BZ: 116218

        Google introduced new method of specifying include path(s)
        between modules. This allows a module to include header from a
        library without directly specifyining by includer the path where
        headers are located.

        The method requires from library that holds headers to export
        include path(s) in LOCAL_EXPORT_C_INCLUDE_DIRS variable.
        These exported include path(s) are automatically added to
        include path(s) of modules that have name of the library in the
        LOCAL_SHARED_LIBRARIES or LOCAL_STATIC_LIBRARIES list.

        This change sets LOCAL_EXPORT_C_INCLUDE_DIRS to folders that
        contain headers file that used by other modules in order to
        export these paths.
