changegroup: refactor emitrevision to use a `deltamode` argument

This new argument gathers the semantic of `sendfulltext` and `deltaprevious`
in a single value. We are about to introduce a new type of constraints.
Avoiding yet another argument sounds like a plus.

# Dummy extension to define a namespace containing revision names

from mercurial import (

def reposetup(ui, repo):
    names = {b'r%d' % rev: repo[rev].node() for rev in repo}
    namemap = lambda r, name: names.get(name)
    nodemap = lambda r, node: [b'r%d' % repo[node].rev()]

    ns = namespaces.namespace(b'revnames', templatename=b'revname',
                              logname=b'revname',
