Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Instead of initializing & interning the strings passed to the profile and trace functions lazily, which incurs extra argument pushing and checks in the C overhead for profiling/tracing, create the strings semi-lazily when the Python code first registers a profile or trace function. This simplifies the trampoline into the profile/trace functions.
