shebangs changed from /usr/bin/python2 to /usr/bin/python3.
(Reminder, various distribution packaging guidelines require use
of explicit python version and don't allow '#!/usr/bin/env python',
regardless of how handy that idiom may be.)

glusterfs.spec(.in) package python{2,3}-gluster and python2 or
python3 dependencies as appropriate.

configure(.ac):
+ test for and use python2 or python3 as appropriate. If build
  machine has python2 and python3, use python3. Override by
  setting PYTHON=/usr/bin/python2 when running configure.
+ PYTHONDEV_CPPFLAGS from python[23]-config --includes is a
  better match to the original python sysconfig.get_python_inc().
  All those other extraneous flags breaks the build.
+ Only change the shebangs once. Changing them over and over
  again, e.g., during a `make glusterrpms` in extras/LinuxRPM
  just sends make (is it really make that's looping?) into an
  infinite loop. If you figure out why, let me know.
+ Oldest python2 is python2.6 on CentOS 6 and Debian 8 (Jessie).
  Everything else has 2.7 or 3.x
+ logic from https://review.gluster.org/c/glusterfs/+/21050, which
  needs to be removed/merged after that patch is merged.

Builds on CentOS 6, CentOS 7, Fedora 28, Fedora rawhide, and the
mysterious RHEL > 7.

Please review, it's not always just the comments that were fixed.
I've had to revert of course all calls to creat() that were changed
to create() ...

Only compile-tested!

Fixes glupy.py python2isms, iteritems -> items, and some overlooked 
print() in georep/peer_mountbroker.in

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.

Python 2.7 HMAC does not support Unicode strings. Secret is read
from file so it is possible that glustereventsd reads the content
as Unicode. This patch converts the secret to `str` type before
generating HMAC signature.

Note 1) we're not supposed to be using #!/usr/bin/env python, see
https://fedoraproject.org/wiki/Packaging:Guidelines?rd=Packaging/Guidelines#Shebang_lines

Note 2) we're also not supposed to be using "!/usr/bin/python,
see https://fedoraproject.org/wiki/Changes/Avoid_usr_bin_python_in_RPM_Build#Quick_Opt-Out

The previous patch (https://review.gluster.org/19767) tried to do too
much in one patch, so it was abandoned.

This patch does two things:
1) minor cleanup of configure(.ac) to explicitly use python2
2) change all the shebang lines to #!/usr/bin/python2 and add them
where they were missing based on warnings emitted during rpmbuild.

In a follow-up patch python2 will eventually be changed to python3.

Before that python2-isms (e.g. print, string.join(), etc.) need to be
converted to python3. Some of those can be rewritten in version agnostic
python. E.g. print statements become print() with "from __future_ import
print_function". The python 2to3 utility will be used for some of those.
Also Aravinda has given guidance in the comments to the first patch for
changes.

With Gluster 4.0 we will not provide the server components for EL6 and
older. At one point Gluster 4.x will get GlusterD2, which requires
Golang tools in the distribution. EL6 does not contain these at the
moment.

With this change, it is possible to `./configure --without-server` which
prevents building glusterd and the xlators for the bricks. Building RPMs
can pass `--without server` and the glusterfs-server sub-package will
not be created.
