run-tests: create classes for representing tests

Currently, the state for an individual test is scattered across a number
of functions and variables. This patch begins a process of isolating a
single test's state into instances of a class. It does this by
establishing a new Test base class and child classes for Python tests
and T tests. The class currently has a run() API that proxies into the
existing "runner" functions. Upcoming patches will move the logic for
each test type into the class.

test that new files created in .hg inherit the permissions from .hg/store


  $ "$TESTDIR/hghave" unix-permissions || exit 80

  $ mkdir dir

just in case somebody has a strange $TMPDIR

  $ chmod g-s dir
  $ cd dir

  $ hg init repo
  $ cd repo

  $ chmod 0770 .hg/store

before commit
store can be written by the group, other files cannot
store is setgid

  $ python ../printmodes.py .

  $ mkdir dir
  $ touch foo dir/bar
  $ hg ci -qAm 'add files'

after commit
working dir files can only be written by the owner
files created in .hg can be written by the group
(in particular, store/**, dirstate, branch cache file, undo files)
new directories are setgid

Test that we don't lose the setgid bit when we call chmod.
Not all systems support setgid directories (e.g. HFS+), so
just check that directories have the same mode.

  $ cd ..
  $ hg init setgid
  $ cd setgid
  $ chmod g+rwx .hg/store
  $ chmod g+s .hg/store 2> /dev/null || true
  $ mkdir dir
  $ touch dir/file
  $ hg ci -qAm 'add dir/file'
  $ storemode=`python ../mode.py .hg/store`
  $ dirmode=`python ../mode.py .hg/store/data/dir`
  $ if [ "$storemode" != "$dirmode" ]; then
  >  echo "$storemode != $dirmode"
  > fi
  $ cd ..

  $ cd .. # g-s dir
