global: mass rewrite to use modern exception syntax

Python 2.6 introduced the "except type as instance" syntax, replacing
the "except type, instance" syntax that came before. Python 3 dropped
support for the latter syntax. Since we no longer support Python 2.4 or
2.5, we have no need to continue supporting the "except type, instance".

This patch mass rewrites the exception syntax to be Python 2.6+ and
Python 3 compatible.

This patch was produced by running `2to3 -f except -w -n .`.
