fetch2: Add checksum capability for crate fetcher

This change brings checksum verification of each crate
in a recipe, e.g

| SRC_URI += " \
|     crate://crates.io/aho-corasick/0.7.20 \
|     crate://crates.io/atomic-waker/1.1.0 \
|     crate://crates.io/cc/1.0.79 \
| "
|
| SRC_URI[aho-corasick.sha256sum] = "cc936419f96fa211c1b9166887b38e5e40b19958e5b895be7c1f93adec7071ac"
| SRC_URI[atomic-waker.sha256sum] = "debc29dde2e69f9e47506b525f639ed42300fc014a3e007832592448fa8e4599"
| SRC_URI[cc.sha256sum] = "50d30906286121d95be3d479533b458f87493b30a4b5f79a607db8f5d11aa91f"

That will require to move the checksum initialization
after the possible call to urldata_init method in order
for the crate fetcher to parse the url.

Another way of doing could have been implementing a decodeurl
method that would have been specific for each fetcher class.
