tests in sre_patch back to previous version

- fixed return value from findall

- renamed a bunch of functions inside _sre (way too
  many leading underscores...)

</F>

- removed some hacks that worked around 1.6 alpha bugs
- removed bogus test code from sre_parse

Correct exception information in one docstring.

Greg, this is yours!

we can run "sdist" on a distribution with old-style extension structures
even if we haven't built it yet.  Bug spotted by Harry Gebel.

Changed 'prune_file_list()' so it also prunes out RCS and CVS directories.
Added 'is_regex' parameter to 'select_pattern()', 'exclude_pattern()',
  and 'translate_pattern()', so that you don't have to be constrained
  by the simple shell-glob-like pattern language, and can escape into
  full-blown regexes when needed.  Currently this is only available
  in code -- it's not exposed in the manifest template mini-language.
Added 'prune' option (controlled by --prune and --no-prune) to determine
  whether we call 'prune_file_list()' or not -- it's true by default.
Fixed 'negative_opt' -- it was misnamed and not being seen by dist.py.
Added --no-defaults to the option table, so it's seen by FancyGetopt.

accepted yet!)

This patch fixes a problem on AIX with the signed int case code in
getargs.c, after Trent Mick's intervention about MIN/MAX overflow
checks. The AIX compiler/optimizer generates bogus code with the
default flags "-g -O" causing test_builtin to fail: int("10", 16) <>
16L. Swapping the two checks in the signed int code makes the problem
go away.

Also, make the error messages fit in 80 char lines in the
source.

Avoid calling the dealloc function, previously triggered with
DECREF(inst).  This caused a segfault in PyDict_GetItem, called with a
NULL dict, whenever inst->in_dict fails under low-memory conditions.

The depth field was never decremented inside w_object(), and it was
never initialized in PyMarshal_WriteObjectToFile().

This caused imports from .pyc files to fil mysteriously when the .pyc
file was written by the broken code -- w_object() would bail out
early, but PyMarshal_WriteObjectToFile() doesn't check the error or
return an error code, and apparently the marshalling code doesn't call
PyErr_Check() either.  (That's a separate patch if I feel like it.)

mislabeled.

(Using -c and then -e rearranges some comments, so I won't check that
in -- but it's a good test anyway.

Note that pindent is not perfect -- e.g. it doesn't know about
triple-quoted strings!)

Problem:
A Python program can be completed and reformatted using
Tools/scripts/pindent.py. Unfortunately there is no option for removal
of the generated "# end"-tags.  Although a few Python commands or a
"grep -v '# end '" can do wonders here, there are two drawbacks:
- not everyone has grep/time to write a Python script
- it is not checked whether the "# end"-tags were used validly

Solution:
add extra option "-e" (eliminate) to pindent.py

Fix warnings on 64-bit build build of signalmodule.c

- Though I know that SIG_DFL and SIG_IGN are just small constants,
there are cast to function pointers so the appropriate Python call is
PyLong_FromVoidPtr so that the pointer value cannot overflow on Win64
where sizeof(long) < sizeof(void*).

This patch fixes cPickle.c for 64-bit platforms.

- The false assumption sizeof(long) == size(void*) exists where
PyInt_FromLong is used to represent a pointer. The safe Python call
for this is PyLong_FromVoidPtr. (On platforms where the above
assumption *is* true a PyInt is returned as before so there is no
effective change.)

- use size_t instead of int for some variables

Added an example of using an HTTP POST request.
