blackbox: add configitem for format of log timestamps Sometimes blackbox logs are used to report performance problems, but the timestamps are only at second granularity, so often the timings have to stated separately by the reporter. This is inconvenient and error-prone, so I would like to include %f in the date format. This patch makes that possible.

narrow: rework logic to check whether we need to widen and narrow This patch reworks logic which calculates whether we need to extend or narrow our working copy or not. We filter the addincludes, removeincludes, addexcludes and removeexcludes passed from user to the actual added and removed includes and excludes. What that means is a user can pass an already included path as addincludes, a path which is not included as removeincludes etc. In such situations the old logic use to think we need to do some work, whereas we don't need to do that work. In old logic, even if we don't have anything new to include but it believes we need to call widen, this adds some good amount of work on large repository. A widen calls involves computing incomming csets, calling the narrow_widen() which in non-ellipses cases goes through all the set of csets which are available which can take ~2-3 mins on large repos. Those 2-3 minutes are spend on doing nothing which a client can prevent by checking is there really anything which needs to be included. The tests changes shows that we don't go to the server anymore in such cases which is nice. Differential Revision: https://phab.mercurial-scm.org/D5183
