libsparse: fix 32 bit overflow when calculating last chunk
last_block * s->block_size can overflow when writing large filesystems,
cast to 64 bits before multiplying.

libsparse: rename symbols that conflict with libext4_utils
Until ext4_utils switches to using libsparse, libext4_utils defines some
of the same symbols as libsparse. Fastboot links statically against
both of them, and there is no easy way to make the symbols hidden, so
just rename them in libsparse.

libsparse: add sparse_file_len
Add sparse_file_len, which will compute the size of data that would
be produced if sparse_file_write was called. Useful combined with
sparse_file_callback.

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: add callback output file type
Add a new output file subclass that will call a callback for
each block as it is written. Will be used to measure the space
used by each sparse block to allow resparsing files.
Also add sparse_file_callback, which will write out a sparse
file by calling the provided write function.

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.
