libext2fs: add ext2fs_find_first_set_{block,inode}_bitmap2()
Add functions which try to find the first set block or inode in a
bitmap. This is useful when trying to allocate a range of blocks
efficiently.
Like the find_first_zero family of functions, provide a generic O(N)
search function which will be used if there is no optimized version
provided by the red-black tree or bitarray functions.
Also, expand the test cases for ext2fs_find_first_zero_*() functions.
