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.
