Test for correct lineno on list, tuple, dict literals.

The problem of checking too eagerly for recursive calls is the
following: if a RuntimeError is caused by recursion, and if code needs
to normalize it immediately (as in the 2nd test), then
PyErr_NormalizeException() needs a call to the RuntimeError class to
instantiate it, and this hits the recursion limit again...  causing
PyErr_NormalizeException() to never finish.

Moved this particular recursion check to slot_tp_call(), which is not
involved in instantiating built-in exceptions.

Backport candidate.

constructor, meaning it is treated as *args, not as a single argument.  This
means using the 'message' attribute won't work (until Py3K comes around),
and so one must grab from 'arg' to get the error number.

os.environ (setting envar COLUMNS), which at least caused
test_float_default() to fail if the tests were run more than once.

This repairs the test_optparse -R failures Neal reported on
python-dev.  It also explains some seemingly bizarre test_optparse
failures we saw a couple weeks ago on the buildbots, when
test_optparse failed due to test_file failing to clean up after
itself, and then test_optparse failed in an entirely different
way when regrtest's -w option ran test_optparse a second time.
It's now obvious that make_parser() permanently changing os.environ
was responsible for the second half of that.

Use ctypes.util.find_library to locate the C runtime library
on platforms where is returns useful results.

is_term_resized, resize_term and resizeterm. This uses three
separate configure checks (one for each function).
