bash_completion: support record command

subrepo: fix svnsubrepo.dirty() checking of ignoreupdate (issue2499) The ignoreupdate flag to subrepo.dirty(), introduced in be7e8e9bc5e5, is correctly checked with this change.

test-mq-subrepo.t: correctly forward stdin to test functions - stdin was not forwarded in testrm1 and testrm2 - Forwarding content with EOL using command substitution (`foo`) does not work correctly, the lines are joined together which breaks the prompt readline. - EOFError is raised in ui.prompt() if the input is too short on Linux while OSX treats it as an empty line.

filelog: move metadata parsing to a helper function

revlog: break hash checking into subfunction

ui: add configpath helper

tests: check visibility of pending changesets Verify that pending changesets are seen by pretxn* hooks but not by other processes that access the destination repo while the hooks are running.
