cleanup: make all uses of timedcm specify what they're timing
It's not used in the timing itself, but it's valuable for the trace
events we emit.

demandimport: instrument python 2 code with trace events
This causes the evaluation of an import in Python 3 to emit some trace
data. There's some interesting wrinkles in here, like the fact that
before we even hit dispatch we've demand-imported `sys` several times,
despite the fact that `sys` was already fully loaded as one of the
first few statements in the `hg` script. I don't think that's actually
costing us a ton of performance, but it's probably something we should
investigate fixing some day.

tracing: new module to make tracing events in hg easier
This lives in hgdemandimport because I want to instrument a bunch of
low-level stuff including the bare `hg` script and demandimport, so it
can't live at a higher layer.

contrib: new script to read events from a named pipe and emit catapult traces
I'm starting to get more serious about getting some insight into where
we're spending our time, both in hg itself but also in the test
suite. As a first pass, I'm going to try and produce catapult
traces[0] that can be viewed with Chrome's `about:tracing` tool.

fastannotate: pconvert paths from the server for Windows
I'm guessing that the right thing to do here is to convert the paths on the
server, but I know this is a WIP, and I don't know where that needs to happen.
I'm just trying to eliminate the malicious path warnings in the tests.
