    fix compiler warnings in hurd/ext2fs
    
    ext2fs: Fix compiler warnings.
    
    * ext2fs/balloc.c: Use unsigned char instead of char.
    * ext2fs/bitmap.c Use unsigned char for bitmaps.
    * ext2fs/dir.c: Fix format.
    * ext2fs/ext2fs.h: Use unsigned char for bitmaps.
    * ext2fs/ialloc.c: Use unsigned char for bitmaps. Fix format string in
    ext2_warning.
    * ext2fs/pager.c: Fix format string in ext2_warning and ext2_error.
