hgweb: fix changeset link in annotate view.

shortuser should stop before the first space character. Examples: "Foo Bar <foo.bar AT example DOT com>" -> "foo.bar" (instead of "foo.bar AT example DOT com>" as it was before.) "Foo Bar" -> "Foo"

hgweb: make annotate line revisions point to annotation for that rev

hgweb: fix annotate bugs The parent and child links were broken.

hgweb: use filectx.annotate instead of filelog

Refactor annotate copy support.

findcopies: use dirstate rename information

dirstate: add copies function rename copies to copymap

Add core copy detection algorithm This adds findcopies, which detects merge-relevant copies between files in a pair of manifests back to the merge ancestor. While the merge code invokes the copy detection routine, it does not yet use the result.

context: change filectx repr to use @ Avoids confusion with rev:nodeid syntax used elsewhere

optimize revlog.lookup when passed hex(node)[:...] Instead of converting each node from the filenode to a hex form, convert the arg to a bin form. For a revlog with 26711 entries, doing 100 lookup: before: ~18s after : ~13s

cleanups in revlog.lookup - add comments - do a clean separation of the different cases - don't use a list of each possible node when doing the lookup, just keep the previous entry

context: add __repr__ methods

filectx: lazy linkrev usage

restore filectx.changectx() method

fix newline in error message

add comments in cachefunc

filectx.annotate: return filectx for each line instead of rev

Add cachefunc to abstract function call cache

Make filectx lazier - some users never use filenode

context: handle fileid or changeid == 0

merge with crew

mq: Add --rev argument to qimport, to adopt existing changesets.
