wireprotov2: send protocol settings frame from client

Now that we have client and server reactor support for protocol
settings and encoding frames, we can start to send them out over
the wire!

This commit teaches the client reactor to send out a protocol
settings frame when needed. The httpv2 peer has been taught to
gather a list of supported content encoders and to advertise them
through the client reactor.

Because the client is now sending new frame types by default, this
constitutes a compatibility break in the framing protocol. The
media type version has been bumped accordingly. This will ensure
existing clients won't attempt to send the new frames to old
servers not supporting this explicit media type. I'm not bothering
with the BC annotation because everything wireprotov2 is highly
experimental and nobody should be running a server yet.

Initial setup.

  $ hg init repo
  $ cd repo
  $ touch thefile
  $ hg ci -A -m 'Initial commit.'

Create a tag.

  $ hg tag branchortag

Create a branch with the same name as the tag.

  $ hg branch branchortag
  marked working directory as branch branchortag
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci -m 'Create a branch with the same name as a tag.'

This is what we have:
