tests: avoid unexpected result at invocation of *.py file on Windows

Invocation of "diff tool.py" in test-extdiff.t tests whether
shellquote() is applied on specified command as expected.

But direct invocation of "*.py" file might cause unexpected result on
Windows according to suffix binding.

For example, starting IDE, showing dialog to choose program to be
used, and so on. In such case, running test-extdiff.t is easily timed
out.

This patch uses intermediate *.bat file on Windows, to avoid such
unexpected result. Naming that intermediate file as "diff tool.bat" is
enough to test applying shellquote().

Verify that pending changesets are seen by pretxn* hooks but not by other
processes that access the destination repo while the hooks are running.

The hooks (python and external) both reject changesets after some think time,
during which another process runs pull.  Each hook creates a file ('notify') to
indicate to the controlling process that it is running; the process removes the
file to indicate the hook can terminate.

utility to run the test - start a push in the background and run pull

  $ dotest() {
  >     rm -f notify
  >     printf 'push '; hg -R child-push tip --template '{node}\n'
  >     hg -R child-push -q push > push.out 2>&1 &
  > 
  >     # wait for hook to create the notify file
  >     i=$maxwait
  >     while [ ! -f notify -a $i != 0 ]; do
  >         sleep 1
  >         i=`expr $i - 1`
  >     done
  > 
  >     # run pull
  >     hg -R child-pull -q pull
  >     rc=$?
  > 
  >     # tell hook to finish; notify should exist.
  >     rm notify
  >     wait
  > 
  >     cat push.out
  >     printf 'pull '; hg -R child-pull tip --template '{node}\n'
  >     return $rc
  > }
