wireproto: use CBOR for command requests
Now that we're using CBOR in the new wire protocol, let's convert
command requests to it.
Before I wrote this patch and was even thinking about CBOR, I was
thinking about how commands should be issued and came to the
conclusion that we didn't need separate frames to represent the
command name from its arguments. I already had a partially
completed patch prepared to merge the frames.
But with CBOR, it makes the implementation a bit simpler because
we don't need to roll our own serialization.
The changes here are a bit invasive. I tried to split this into
multiple commits to make it easier to review. But it was just too
hard.
* "command name" and "command argument" frames have been collapsed
into a "command request" frame.
* The flags for this new frame are totally different.
* Frame processing has been overhauled to reflect the new order
of things.
* Test fallout was significant. A handful of tests were removed.
Altogether, I think the new code is simpler. We don't have
complicated state around receiving commands. We're either receiving
command request frames or command data frames. We /could/
potentially collapse command data frames into command request
frames. Although I'd have to think a bit more about this before
I do it.

==================================== Testing head checking code: Case D-6 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category D: remote head is "obs-affected" locally, but result is not part of the push TestCase 6: single changeset, superseeded then pruned (on a new changeset unpushed) changeset This is a partial push variation of case B-6 .. old-state: .. .. * 1 changeset branch .. .. new-state: .. .. * old branch is rewritten onto another one, .. * the new version is then pruned. .. .. expected-result: .. .. * push denied .. .. graph-summary: .. ..
