tests: check metadata and long description using `setup.py check`

This probably isn't very useful to us, since at the moment the metadata check
cares only about the presence of "name" and "version", and the reST check makes
sure our long_description renders properly (we build the docs, so we would
probably see any render errors, just in a different place), but this is a
simple command, so let's add it.

  $ . $TESTDIR/testlib/topic_setup.sh

Code logically equivalent to the following is used in Zsh to show the branch
and topic (if set) in the prompt. If the format of the files is changed in a
way that it breaks the test, a mail should be sent to [e-mail].

  $ get_branch_like_zsh() {
  >     branchfile=".hg/branch"
  >     topicfile=".hg/topic"
  >     if [ -r "${branchfile}" ] ; then
  >         r_branch=$(cat "${branchfile}")
  >     fi
  >     if [ -f "${topicfile}" ] && [ -r "${topicfile}" ] && [ -s "${topicfile}" ] ; then
  >         IFS= read -r REPLY < ${topicfile}
  >         r_branch=${r_branch}:${REPLY}
  >     fi
  >     echo $r_branch
  > }
