debugcommands: support for sending "batch" requests

Let's teach `hg debugwireproto` to send "batch" requests.

The easiest way to implement this was as a pair of instructions to
begin and end a batched operation. Otherwise, we would have to reinvent
the parsing wheel or factor out the parsing code.

To prove it works, we add a batched request to test-ssh-proto.t.

Helper function to run protocol tests against multiple protocol versions.
This is easier than using #testcases because managing differences between
protocols with inline conditional output is hard to read.

A no-op connection performs a handshake

  $ hg debugwireproto --localssh << EOF
  > EOF
  creating ssh peer from handshake results

Raw peers don't perform any activity

  $ hg debugwireproto --localssh --peer raw << EOF
  > EOF
  using raw connection to peer
  $ hg debugwireproto --localssh --peer ssh1 << EOF
  > EOF
  creating ssh peer for wire protocol version 1
  $ hg debugwireproto --localssh --peer ssh2 << EOF

  creating ssh peer for wire protocol version 2

Test a normal behaving server, for sanity

>=0.9.1 clients send a "hello" + "between" for the null range as part of handshake.
Server should reply with capabilities and should send "1\n\n" as a successful
reply with empty response to the "between".
