Thanks Andrew Gaul.

Backported 2.3.

Added socket.error to the socket module's C API.

Test suites for urllib and urlparse run with each other's function to verify
correctness of replacement and both test suites pass.

Bumped urllib's __version__ attribute up a minor number.

Backported to 2.3.

requires and provides. requires is a sequence of strings, of the
form 'packagename-version'. The dependency checking so far merely
does an '__import__(packagename)' and checks for packagename.__version__
You can also leave off the version, and any version of the package
will be installed.
There's a special case for the package 'python' - sys.version_info
is used, so
requires= ( 'python-2.3', )
just works.

Provides is of the same format as requires - but if it's not supplied,
a provides is generated by adding the version to each entry in packages,
or modules if packages isn't there.
Provides is currently only used in the PKG-INFO file. Shortly, PyPI
will grow the ability to accept these lines, and register will be
updated to send them.

There's a new command 'checkdep' command that runs these checks.
For this version, only greater-than-or-equal checking is done. We'll
add the ability to specify an optional operator later.

This fixes a problem that math.sqrt(-1) doesn't raise math.error.

Fixes SF Bug #850981

It's possible to create insane datetime objects by using the constructor
"backdoor" inserted for fast unpickling.  Doing extensive range checking
would eliminate the backdoor's purpose (speed), but at least a little
checking can stop honest mistakes.

Bugfix candidate.

the newly created tuples, but tuples added in the freelist are now cleared in
tupledealloc already (which is very cheap, because we are already
Py_XDECREF'ing all elements anyway).

Python should have a standard Py_ZAP macro like ZAP in pystate.c.

[Part of patch #909005] Repeating exception changed from 'raise socket.error, why' to just raise.  Make use of connect_ex() raise socket.error with 2-tuple instead of just error code
