libext2fs: Add new function ext2fs_test_inode_bitmap_range()

Optimize ext2fs_test_block_bitmap_range() and add a new function,
ext2fs_test_inode_bitmap_range(), which works the same way as
ext2fs_block_bitmap_range() but for inode bitmaps.  It's needed for
some code in the development branch, so let's drop it into the maint
branch to make life easier in the future.
