append2simg causes libsparse to write mmapped data from a file
back to that same file. On btrfs, this sometimes causes a page
of zeroes to be written instead of the file data. Work around
the issue by writing the output to a temporary file and then
renaming it over the original file.

Append2simg is a small utility designed to glue data to the end
of a sparse image. Beware that it doesn't do anything clever with
that data.

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.

Abstract the logic from simg2img into libsparse, and add logic
for reading a regular image into libsparse. simg2img then
becomes a simple wrapper around libsparse.
img2simg was not actually making the file sparse, it was using
sparse files to create multiple files that could be pieced back
together. Replace it with a simple wrapper around libsparse.
Its functionality will be replaced by an simg2simg that can
resparse a file into smaller chunks.

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.
