[ 561724 ] README additions for Cray T3E

Lightly edited by me.

imports of test modules now import from the test package.  Other
related oddities are also fixed (like DeprecationWarning filters that
weren't specifying the full import part, etc.).  Also did a general
code cleanup to remove all "from test.test_support import *"'s.  Other
from...import *'s weren't changed.

pass -DHAVE_CONFIG_H to CC, and that symbol isn't used any more.

The "Matching vs. Searching" Info node is unreachable from the Info
program (but is fine in Emacs's Info mode). This patch seems to fix
it.  This is the only occurrence where the info reader fails, so
probably it could be addressed in the python docs as a workaround.
Forwarded the report to the info maintainer.

Clarify LLTRACE description.  It was introduced in 1992, revision 2.20 of
ceval.c, well before Python 1.0!

Revert changes to use PyArg_Parse(), so any sequence will continue to work -- Spotted by Just van Rossum

See there for a description.

Added test case.

Bugfix candidate for 2.2.x, not sure about previous versions:
probably low priority, because virtually no one runs debug builds.

doubleclicks a .py, .pyw or .pyc file. It runs the file by invoking the
relevant interpreter (either the command line Python in a terminal window
or a Python.app for GUI-based scripts). Interpreter to use and the options
to pass are settable through preferences.

If PythonLauncher wasn't running it does its thing for one script and exits.
If it was manually started before a dialog is presented where the user
can set the options to use, etc.

To be done:
- option-drag/doubleclick should always open the interactive dialog
- Terminal-window isn't done yet
- Should be reimplemented in Python, but pyobjc isn't part of the core.
- Various menu entries should be disabled.

This patch fixes make install for Cygwin. Specifically,
it reverts to the previous behavior:

o install libpython$(VERSION)$(SO) in $(BINDIR)
o install $(LDLIBRARY) in $(LIBPL)

It also begins to remove Cygwin's dependency on
$(DLLLIBRARY) which I hope to take advantage of
when I attempt to make Cygwin as similar as possible
to the other Unix platforms (in other patches).

I tested this patch under Red Hat Linux 7.1 without
any ill effects.

BTW, I'm not the happiest using the following
test for Cygwin:

test "$(SO)" = .dll

I'm willing to update the patch to use:

case "$(MACHDEP)" in cygwin*

instead, but IMO that will look uglier.

[ 587875 ] crash on deleting extended slice

The array code got simpler, always a good thing!

 PyErr_SetExcFromWindowsErr(), PyErr_SetExcFromWindowsErrWithFilename().

Similar to PyErr_SetFromWindowsErrWithFilename() and
PyErr_SetFromWindowsErr(), but they allow to specify
the exception type to raise. Available on Windows.

See SF patch #576458.

also adds 'extern' to PyAPI_DATA rather than at each declaration, as
discussed with Tim and Guido.
