    Fixed some compilation warning/error or error checking.
    
    There is one compilation error ,cast int to pointer, when built without
    libgbm, reported by Gaetan Nadon.
    And some error checking after memory allocation, reported by Seth Arnold.
    There are still some similar issues in the largepixmap implementation.
    They are relatively more complicate due to the heavy usage of RegionXXX
    APIs which may allocate implicitly. Will fix them in the future.
