Add support to fastboot for automatically using libsparse to break large files, whether they are in sparse or normal format, into multiple sparse files that can each fit into the target's memory. Allows flashing images that are larger than the size of the available memory on the target. By default, any file over 512MB will be sparsed into 512MB chunks. The limit can be modified with the -m argument, or sparsing can be forced with -S or avoided with -N. If -m is not specified, the target can override the default by implementing getvar:max-download-size Change-Id: I6c59381c3d24475c4f2587ea877200b96971cbd7
