Series [PULL,01/61] docs/sphinx: create QAPI domain extension stub | expand

Commit Message

From: John Snow <jsnow@redhat.com>

Add the .. qapi:alternate:: directive, object, and qapi:alt:`name`
cross-reference role.

Add the "Alternatives:" field list for describing alternate choices. Like
other field lists that reference QAPI types, a forthcoming commit will
add cross-referencing support to this field.
