[bitbake-devel][PATCH v2 3/3] crate.py: authorize crate url with parameters

[frederic.martinsons@gmail.com]

From: Frederic Martinsons <frederic.martinsons@gmail.com>

This allow to have classic fetch parameters
(like destsuffix, sha256, name ...) not being
considered by crate fetcher itself (and so mess
up its download)

Moreover, it allow to overload the name of the downloaded
crate (maybe usefull if there is a naming clash between
two crates coming from different repositories)
