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.
