raise InvalidOperation (and return False if InvalidOperation is trapped).

Should not be merged to py3k branch.

Thanks Giampaolo Rodola.

Calendar.yeardays2calendar() and Calendar.yeardayscalendar() as the methods
don't have such a parameter. Fixes issue #2017.

Rewrap content to 80 chars.

in Object/ are named ``free_list``, the counter ``numfree`` and the upper
limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.

The chances should make it easier to adjust Python for platforms with
less memory, e.g. mobile phones.

* Convert both to unittest.
* Use the same unit testing code.
* Include the expected output in both test files.
* Make it possible to regenerate the expected output by running
  the file as a script with an '-r' argument.

(This code is duplicated between pydoc and DocXMLRPCServer; maybe it
should be refactored as a GHOP project.)

2.5.2 backport candidate.

(will backport to 2.5)

there is no need to emit co_lnotab item when both offsets are zeros.

The mapping between bytecode offsets and source lines (lnotab) did not contain
an entry for the beginning of the loop.

Now it does, and the lnotab can be a bit larger:
in particular, several statements on the same line generate several entries.
However, this does not bother the settrace function, which will trigger only
one 'line' event.

The lnotab seems to be exactly the same as with python2.4.

I implemented the function sys._compact_freelists() and C API functions PyInt_/PyFloat_CompactFreeList() to compact the pre-allocated blocks of ints and floats. They allow the user to reduce the memory usage of a Python process that deals with lots of numbers.
The patch also renames sys._cleartypecache to sys._clear_type_cache

to the main mailbox, copy it to secondary mailbox instances.

Add PyFrozenSet_Check(), which was not needed before; The list of Py*Set_Check* macros seems to be complete now.

Add missing NEWS entries about all this.

Use vsbuild instead of devenv in build.bat and _bsddb.vcproj
