Answer every seat call within ten seconds and keep what came of it (hq issue 265)

A push outlasted the console's 30s wait and, when it sent the bus its
changed user list, the broker's reload forgot the reply it may send:
the push happened and its caller was told it did not answer. Calls now
answer in full or as running with an id, a push answers before it
sends, refused answers are recorded on their call, and 'calls' reads
them back.
