ctrl: tighten CTRL input parsing

Validate that incoming CTRL commands...
- have decimal IDs,
- return error on trailing characters,
- have invalid characters in variable identifiers,
- send detailed error messages as reply to the requestor.

Adjust ctrl_test.{c,ok}, which best show the change in behavior.

Message handling causes log messages on stderr; previously, stderr was empty.
Add '[ignore]' in testsuite.at so that the nonempty stderr doesn't cause test
failures.
