debug: add debugwireargs to test argument passing over the wire

Tests argument passing locally, via HTTP, and via SSH. This is mainly preparation
for the next patch.

Test wire protocol argument passing

Setup repo:

  $ hg init repo

Local:

  $ hg debugwireargs repo eins zwei
  eins zwei None None

HTTP:

  $ hg serve -R repo -p $HGPORT -d --pid-file=hg1.pid -E error.log -A access.log
  $ cat hg1.pid >> $DAEMON_PIDS

  $ hg debugwireargs http://localhost:$HGPORT/ eins zwei
  eins zwei None None
  $ cat access.log
  * - - [*] "GET /?cmd=capabilities HTTP/1.1" 200 - (glob)
  * - - [*] "GET /?cmd=debugwireargs&one=eins&two=zwei HTTP/1.1" 200 - (glob)
  * - - [*] "GET /?cmd=debugwireargs&one=eins&two=zwei HTTP/1.1" 200 - (glob)

SSH (try to exercise the ssh functionality with a dummy script):

  $ cat <<EOF > dummyssh
  > import sys
  > import os
  > os.chdir(os.path.dirname(sys.argv[0]))
  > if sys.argv[1] != "user@dummy":
  >     sys.exit(-1)
  > if not os.path.exists("dummyssh"):
  >     sys.exit(-1)
  > os.environ["SSH_CLIENT"] = "127.0.0.1 1 2"
  > r = os.system(sys.argv[2])
  > sys.exit(bool(r))
  > EOF

  $ hg debugwireargs --ssh "python ./dummyssh" ssh://user@dummy/repo eins zwei
  eins zwei None None
