sparse: don't enable on clone if it was a narrow clone When both sparse and narrow extensions are enabled and we do a narrow clone, sparse enables itself because it reads --include flag and thinks that user is trying to do a sparse clone. This patch changes that behavior, and now if both extensions are enabled and user passes `--narrow`, then the includes and excludes won't be considered as part of sparse profile.

tests: add tests for narrow clone when both sparse and narrow are enabled This patch adds tests for doing a narrow clone when client has both sparse and narrow enabled. As shown by this patch, we can see that the narrow clone has sparse enabled which we does not want here. Upcoming patch will fix this. Also while writing tests, I realized we don't have a flag to list the current sparse profile. Differential Revision: https://phab.mercurial-scm.org/D5478

progress: check what type of progress bar to use only once per topic This seems to have sped up `hg perfprogress` from 1.78 s to 1.41 s. Differential Revision: https://phab.mercurial-scm.org/D5530

progress: split up _print() method in bar-updating and debug-printing I just thought this was clearer, but it turned out to also simplify the next patch. This seems to have sped up `hg perfprogress` from 1.85 s to 1.78 s. Differential Revision: https://phab.mercurial-scm.org/D5529

progress: move cached debug flag from progress.progbar to scmutil.progress It's simpler this way. One possible drawback (and a possisble advantage) is that we now check the debug flag once per topic, so processes that generate new topics all the time will still check the flag frequently.

progress: write ui.progress() in terms of ui.makeprogress() I think ui.makeprogress() should be the preferred interface and we should deprecate ui.progress(). All in-core callers already use ui.makeprogress(). Moving the logic to the scmutil.progress() will let us make further improvements. This seems to have sped up `hg perfprogress` from 1.92 s to 1.85 s, perhaps because we now skip the indirection of updating the progress bar via ui.progress().
