libsparse: use strcmp and validate last_used pointer
This patch is used to fix two Bugs in backed_block.c
First, fix wrong comparing string way: we should use strcmp rather than
just compare their address. Second, fix using illegal memory risk in
bbl->last_used pointer. When entering queue_bb function,
bbl->last_used = new_bb, but in the following code if
queue_bb(xx, bb, new_bb) return ok, the space of new_bb is released. So
next time, if you use bbl->last_used pointer, may cause segment fault !

libsparse: add function to resparse a file and a utility to use it
Add sparse_file_repsarse, which splits chunks in an existing sparse
file such that the maximum size of a chunk, plus a header and footer,
is smaller than the given size. This will allow multiple smaller
sparse files to result in the same data as a large sparse file.

libsparse: merge adjacent blocks of the same type
When a block is added that is adjacent to another block and of the same
type, merge it. This will be useful for converting regular images to
sparse images, allowing the reader to add a single block at a time and
letting libsparse optimize into larger blocks as it goes.
Does not support merge two blocks that are backed by a data pointer,
only blocks that are backed by a file for now.

libsparse: add support for including fds
Add sparse_file_add_fd to include all or part of the contents
of an fd in the output file. Will be useful for re-sparsing files
where fd will point to the input sparse file.

libsparse: cleanups
Move block loops into sparse.c with iterator helpers in backed_block.c.
Simplify chunk writing by moving skip chunk calls from output_file.c to
sparse.c.
Rename variables to be consistent with new naming.
Remove use of u8, u32, u64.

system/core: move libsparse into system/core
This moves an exact copy of libsparse from
system/extras/ext4_utils/libsparse to system/core/libsparse in
preparation for linking tools in system/core against it.
