qapi: Reject multiple and empty feature descriptions
The parser recognizes only the first "Features:" line. Any subsequent
ones are treated as ordinary text, as visible in test case
doc-duplicate-features. Recognize "Features:" lines anywhere. A
second one is an error.
A 'Features:' line without any features is useless, but not an error.
Make it an error. This makes detecting a second "Features:" line
easier.
qapi/run-state.json actually has an instance of this since commit
fe17522d854 (qapi: Remove deprecated 'singlestep' member of
StatusInfo). Clean it up.
