journal: properly check for held lock (issue5349) The 'jlock' code meant to check for a held lock, but it actually just checking for a lock object. With CPython, this worked because the 'jlock' object is not referenced outside the '_write' function so reference counting would garbage collect it and the '_lockref' would return None. With pypy, the garbage collection would happen at an undefined time and the '_lockref' can still point to a 'jlock' object outside of '_write'. The right thing to do here is not only to check for a lock object but also to check if the lock is held. We update the code to do so and reuse a utility method that exist on 'localrepo' to help readability. This fix journal related tests with pypy.

ssl: handle a difference in SSLError with pypy (issue5348) The SSLError exception is a bit different with pypy (message is the first argument, not the second) This led the certificate error handling to crash when trying to extract the ssl error message. We now handle this different and 'test-https.t' is green again.
