CONFIG_FASTBOOT_FLASH_FILLBUF_SIZE is present since the very first
addition of sparse image support. However its not used anywhere in the
code, so remove it.

chunk_data_sz is set to the result of a __le32 * __le32 multiplication:
chunk_data_sz = si->sparse.blk_sz * si->chunk.chunk_sz;
This will overflow.

retlen can potentially overflow. Also, write_full() in
fastboot_handle_sparse() expects size_t anyway.

This adds support for reading Android fastboot sparse images. This
code is based on the corresponding U-Boot code, but has been heavily
modified to provide a read-like API which better fits into barebox.
