merge the io-c branch: C implementation of the io module
The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.
