core/various: python3 compat, prepare for python2 -> python3

see https://review.gluster.org/#/c/19788/ and
    https://review.gluster.org/#/c/19871/

Selected small fixes from 2to3 utility. Specifically apply, basestring,
funcattrs, idioms, numliterals, set_literal, types, urllib, zip

Note: these 2to3 fixes report no changes are necessary: 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.

Any 2to3 fixes not in the above two lists have more extensive changes
which will follow in separate patches.

most unicode changes suggested by 2to3 will need to be applied at the
same time as changing the shebangs from python2 to python3. Prashanth
notes that unicode strings in py2 need 'u' prefix; unicode strings in
py3 3.0, 3.1, and 3.2 a 'u' prefix will throw an error, but in py3 3.3+
it is legal (or just ignored). All Linux dists we care about have 3.3
or later so we can leave 'u' prefixes on unicode strings.
