convert/gnuarch: follow continuation-of revisions

Built on top of previous patches:
 - continuation-of parsing
 - registered archives retrieval
 - use of fully qualified revisions

This allows the converter scanning for more source revisions
following the tree versions 'leaked' through the continuation-of
informations. Coupled with the registered archives retrieval, this
makes possible to decide to follow such a hint or stop scanning for
more revisions.

This also implies some changes in the retrieval of some base-0
revisions when they're continuation-of other revisions, in that
case a 'replay' will work where a simple 'get' fails because the
dir exists already. I found the code dealing with 'replay' quite
good as it has already a fallback to 'get' in the error path.
