rust: add Debug constraint to Matcher trait

This makes sure we can easily debug which Matcher we're looking at when using
trait objects, and is just generally useful. Effort to make the debugging
output nicer has been kept to a minimum, please feel free to improve.

#require no-chg

persistent-nodemap is not enabled by default. It is not relevant for this test so disable it.

  $ cat << EOF >> $HGRCPATH
  > [format]
  > use-persistent-nodemap = no
  > EOF

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.

  $ debugwireproto() {
  >   commands=`cat -`
  >   echo 'testing ssh1'
  >   echo "${commands}" | hg --verbose debugwireproto --localssh

A no-op connection performs a handshake

  $ hg debugwireproto --localssh << EOF
  > EOF

Raw peers don't perform any activity

  $ hg debugwireproto --localssh --peer raw << EOF

  $ hg debugwireproto --localssh --peer ssh1 << EOF

>=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".
