There were some hardcoded behaviours in the system for which backends support checksums verses which backends recommend them verses which don't recommend them. This moves the functionality into specific fetchers and then makes the general code generic. This cleans up the codebase and fixes some corner cases such as trying to checksum directories returned by the git fetcher.

BitBake 'Fetch' implementations
|
|
|
|
This implementation is for Secure Shell (SSH), and attempts to comply with the
|
|
IETF secsh internet draft:
|
|
http://tools.ietf.org/wg/secsh/draft-ietf-secsh-scp-sftp-ssh-uri/
|
|
|
|
Currently does not support the sftp parameters, as this uses scp
|
|
Also does not support the 'fingerprint' connection parameter.
