templatefilters: remove redundant 'date' and 'strip' filters These filters are defined as 'date()' and 'strip()' functions. Help messages are moved to the corresponding functions.

templater: introduce unified filter syntax for unary functions "filter(expr)" is allowed already. This patch adds the opposite, "expr|func".

templater: inline getfilter() to buildfilter() This prepares for the unified filter syntax that will be introduced by the next patch.

clone: fix updaterev to update to latest branch changeset (issue4528) Before this patch if clone --updaterev points to branch which head on src repo wasnt in dest repo, clone updated dest repo to default branch. After applying this patch, if changeset from src repo pointing at given branch is not in dest repo, it searches for changeset pointing for given branch locally in dest repo. Lookup in destination repo: 559: uprev = destrepo.lookup(update) is wrapped by try/except block to preserve current behaviour when given revset to -u is not found - it will not fail,but silently update dest repo to head of default branch.

revsets: makes follow() supports file patterns (issue4757) (BC) Before this patch, follow only supports full, exact filenames. This patch makes follow argument to be treated like file pattern same way like log treats their arguments. It preserves current behaviour of follow() matching paths relative to the repository root by default.

histedit: improve discoverability of edit commit message

revset: cache smartset's min/max As the content of a smartset never changes, min and max will never change either. This will save us time when this function is called multiple times. This is relevant for issue4782 but does not fix it.
