[Python-3000] CGI module - remove backward-compatibility classes?

[Georg Brandl]

The CGI module has some classes that are marked as "backwards compatibility
only". They are not formally deprecated in the docs, but this can be done
for 2.6. Should we remove them in 3.0?

Thus spake the Lord: Thou shalt indent with four spaces. No more, no less.
Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
