This patch changes uses of map() and raise(), and a few cases of print()
that were overlooked in the prior patch that fixed print.

Note: Fedora packaging guidelines require explicit shebangs, so 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, idioms, numliterals, set_literal, types, urllib,
zip, map, and raise 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, intern, itertools, metaclass,
methodattrs, ne, next, nonzero, operator, paren, raw_input, reduce,
reload, renames, repr, standarderror, sys_exc, throw, tuple_params,
xreadlines.
