gh-115712: Support CSV dialects with delimiter=' ' and skipinitialspace=True (GH-115721) 
Restore support of such combination, disabled in gh-113796.

csv.writer() now quotes empty fields if delimiter is a space and
skipinitialspace is true and raises exception if quoting is not possible.

gh-80527: Change support.requires_legacy_unicode_capi() (#108438) 
The decorator now requires to be called with parenthesis:

    @support.requires_legacy_unicode_capi()

instead of:

    @support.requires_legacy_unicode_capi

The implementation now only imports _testcapi when the decorator is
called, so "import test.support" no longer imports the _testcapi
extension.

bpo-44630: Fix assertion errors in csv module (GH-27127) 
Fix incorrect handling of exceptions when interpreting dialect objects in
the csv module. Not clearing exceptions between calls to
PyObject_GetAttrString() causes assertion failures in pydebug mode (or with
assertions enabled).

Add a minimal test that would've caught this (passing None as dialect, or
any object that isn't a csv.Dialect subclass, which the csv module allows
and caters to, even though it is not documented.) In pydebug mode, the test
triggers the assertion failure in the old code.

Windows and Linux.  The only differences I found were actually tests
that were previously *not* run.
