exchange: refactor bundle specification parsing

The old code was tailored to `hg bundle` usage and not appropriate for
use as a general API, which clone bundles will require. The code has
been rewritten to make it more generally suitable.

We introduce dedicated error types to represent invalid and unsupported
bundle specifications. The reason we need dedicated error types (rather
than error.Abort) is because clone bundles will want to catch these
exception as part of filtering entries. We don't want to swallow
error.Abort on principle.

    A delta based on a censored revision must be formed as single patch
    operation which replaces the entire base with new content. This ensures
    the delta may be applied by clones which have not censored the base.
