bookmarks: rewrite "updatefromremote()" by "compare()" To update entries in bmstore "localmarks", this patch uses "bin(changesetid)" instead of "repo[changesetid].node()" used in original "updatefromremote()" implementation, because the former is cheaper than the latter.

bookmarks: add function to centralize the logic to compare bookmarks This patch adds "compare()" function to centralize the logic to compare bookmarks between two repositories.

hgweb: use semantically suitable filelog.revs in filelog The functions are equivalent in behaviour, so no behavior change.

hgweb: always compute all entries and latestentry in filelog This is the same thing which was done for changelog earlier, and it doesn't affect performance at all. This change will make it possible to get the first entry of the next page easily without computing the list twice.

hgweb: remove unused argument of entries function in filelog This doesn't change the behavior as the argument wasn't used anyway.

transplant: use peer of source repository as "remote" for "repo.pull()" Before this patch, transplant with "--merge" option fails with traceback unexpectedly, if it causes pull from the source repository on the local host. "discovery.findcommonincoming()" invokes "capable()" method on the object given from "localrepository.pull()", but it is "localrepository" object in this case and doesn't have such method. This patch uses peer object of source repository as "remote" argument for "localrepository.pull()" invocation like other invocations of it in transplant.py.

run-tests: remove files that we potentially create outside of $TMPDIR

run-tests: remove code that creates a dummy 'diffstat' This was introduced in fb1d7a42663c for an old test that is no longer the same.

template: change extras to use showlist rather than manual templ call. This enables start_extras and end_extras in template maps.

help: adding example 'extras' printing to 'hg help templates'
