git: convert tz offset to int (issue6359) Differential Revision: https://phab.mercurial-scm.org/D8991

repoview: pin revisions for `local` and `other` when a merge is active I've hit this a couple of times, where pulling with a dirty `wdir` obsoletes `p1` and updating to the successor results in merge conflicts. The problem was resolving them failed immediately, complaining that the old checkout was filtered. The change in `test-rebase-obsolete.t` is because there's an outstanding merge conflict in a rebase operation. The summary prompt to merge seems incorrect for this scenario, but that's an existing issue. Differential Revision: https://phab.mercurial-scm.org/D8980

extdiff: refactor cmdline and gui calculation login in a separate fn This is some good logic with handling of many config items and various ways of specifying it. I want to reuse in `diff --tool` and hence refatcored it in a separate function of it's own.
