Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Tests: cope with resolver resend in mail resolver tests. Currently, if resolver didn't find PTR type in the answer section of PTR response, it keeps the node in the resend queue until the next timer event.
