- since mediafire cannot deal with empty files, we put new files into a
temporary location and upload them once they get closed
- add create and write functions to fuse
- pass a file handle to mfconn_api_upload_simple instead of a path
- allow calc_sha256 to also compute the file size
- error out when the key returned by upload/simple is empty
- make valgrind.supp more lenient
- refactor some code:
- code handling the file cache is now in fuse/filecache.c
- base36 and base16 encoding and decoding moved to utils/hash.c
- mfshell: add "updates" command calling device/get_updates
- add container class to store patch information as mfapi/patch.c
- apicalls: store more info retrieved by file/get_info
- apicalls: add device/get_updates
- apicalls: add device/get_patch
