hgweb: make 'summary' work with hidden changesets (issue3810) Since the 'summary' view used by e.g. gitweb and monoblue shows both a changelog and a bookmarks list, the same changes are needed here as were made to the 'changelog' and 'bookmarks' web commands (56ca4443a343 and 886936ecc21b, respectively).

hgk: support the old way of getting the current Ttk theme (issue3808) It seems like the API has changed somewhere around 8.5.7, so the preferred way of getting the current theme is now [ttk::style theme use], while the deprecated (but still working) is $::ttk::currentTheme.

addremove: don't perform m.exact/rel until needed Moves the m.exact and m.rel calls within the conditionals they are used in. On a large repo this brings addremove from 7.1 seconds down to 6.3 (13%).

addremove: don't call lexists, isdir, and islink The dirstate walk results contain the stat information for each path, so we don't need to query it again. On a large repo this makes addremove go from 8.35 seconds to 7.1 (15%).

addremove: only query dirstate once per path Previously the addremove code queried the dirstate 4 times per path. Now it only does so once. On a large repo this brings addremove from 9.5 seconds to 8.35 seconds (12%).
