global: mass rewrite to use modern octal syntax

Python 2.6 introduced a new octal syntax: "0oXXX", replacing "0XXX". The
old syntax is not recognized in Python 3 and will result in a parse
error.

Mass rewrite all instances of the old octal syntax to the new syntax.

This patch was generated by `2to3 -f numliterals -w -n .` and the diff
was selectively recorded to exclude changes to "<N>l" syntax conversion,
which will be handled separately.
