This patch fixes more selected comma white space (ws_comma) as suggested
by the 2to3 utility. (Earlier attempts to fix all ws_comma in one
patch did not pass centos regression, hence multiple patches to identify
the change that causes the failure.)
Note: Fedora packaging guidelines and SUSE rpmlint require explicit
shebangs; popular practices like #!/usr/bin/env python and #!/usr/bin/python
are not allowed; they must be #!/usr/bin/python2 or #!/usr/bin/python3
Note: Selected small fixes from 2to3 utility. Specifically apply,
basestring, funcattrs, has_key, idioms, map, numliterals, raise,
set_literal, types, urllib, and zip have already been applied. Also
version agnostic imports for urllib, cpickle, socketserver, _thread,
queue, etc., suggested by Aravinda in https://review.gluster.org/#/c/19767/1
Note: these 2to3 fixes report no changes are necessary: asserts, buffer,
exec, execfile, exitfunc, filter, getcwdu, imports2, input, intern,
itertools, metaclass, methodattrs, ne, next, nonzero, operator, paren,
raw_input, reduce, reload, renames, repr, standarderror, sys_exc, throw,
tuple_params, xreadlines.
