Subject: docs/qapi-domain: add :since: directive option
X-Git-Tag: v10.0.0-rc0~11^2~49
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=700d51a45c614068393f9754d3ef366e2c05a884;p=thirdparty%2Fqemu.git

docs/qapi-domain: add :since: directive option

Add a little special markup for registering "Since:" information. Adding
it as an option instead of generic content lets us hoist the information
into the Signature bar, optionally put it in the index, etc.
