ui: rename tmpdir parameter to more specific repopath This was requested by Augie and I agree that repopath is more descriptive.

pager: wrap _runcommand() no matter if stdout is redirected We've made chg utilize the common code path implemented in pager.py (by 815e1cefd082 and 493935e0327a), but the chg server does not always start with a tty. Because of this, uisetup() of the pager extension could be skipped on the chg server. Kudos given to Sean Farley for dogfooding new chg and spotting this problem.

shelve: make unshelve not crash when there are missing files (issue4176) This patch makes it possible to unshelve while having missing files in your repo as long as shelved changes don't touch those missing files. It also makes error message better otherwise.

statprof: require input file statprof has a __main__ handler that allows viewing of previously written data files. As Yuya pointed out during review, f42cd5434cc2 broke this. This patch fixes that.

tests: work around FreeBSD's unzip having slightly different output According to man 1 unzip, this unzip appeared in FreeBSD 8.0. It's what comes as /usr/bin/unzip, so we may as well cater to it since it's easy.

contrib: fix check-commit to not reject commits from `hg sign` and `hg tag` I'm tired of having a spurious red build every time we do a release. Fix it once and for all.
