dirstate: fix call to os.lstat when st is None

honor signals during load of extensions.

dirstate.read: make 15% faster. time to read dirstate for my kernel repo goes from 0.22s to 0.18s.

merge with crew.

dirstate: speed up inner loop of read.

Report on push/pull if heads are merged, too, like for new heads. Use case: If a remote repo has two heads and I _want_ to merge them, I merge and push. Meanwhile someone else pushed on top of one of the heads. He won't get a warning, because he doesn't create a new head, I won't notice that I don't close a head, because I don't get a message telling me.

merge with upstream

add --lsprof option. 3x faster than --profile, more useful output. results include calls to c code and nested calls. requires python 2.5 or lsprof installed from svn at http://codespeak.net/svn/user/arigo/hack/misc/lsprof/

ssh: add capability detection at startup Because older servers don't return any output for unknown commands, it's tricky to add new commands. The approach is this: we add a "hello" command that reports any interesting capabilities (and other things that might be of interest in the future). To detect whether this new command is supported, we issue both it and our startup detection command ("between") at the beginning of a connection.
