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 &gt; 7.

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.

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.

<title>*.pc: Fix include path in Cflags</title>

The include path in glusterfs-api.pc looks like

  -I${includedir}/glusterfs

However, client code will include the glusterfs headers using

  #include &lt;glusterfs/api/glfs.h&gt;

rather than

  #include &lt;api/glfs.h&gt;

which makes the "/glusterfs" part entirely unnecessary.

More importantly, on some platforms such as FreeBSD, the header files
for glusterfs will be installed in /usr/local/include, which is *not*
part of the compiler's default include path, so compilation will fail
with something like

  fatal error: 'glusterfs/api/glfs.h' file not found
  #include &lt;glusterfs/api/glfs.h&gt;
           ^~~~~~~~~~~~~~~~~~~~~~

The fix is to simply drop the extra "/glusterfs". The same change
is applied to other *.pc files as well, althought I haven't actually
tested those.

A test program (gfapi-load-volfile) and the glfsxmp example
application were using the wrong include paths, so they had to be
fixed as well.

Previously glfs_h_lookupat won't follow the symlink, this patch
introduces new flag `follow` which will resolve the same. Applications
linking against the new library will need to use the new glfs_h_lookupat
API call.

In order to stay compatible with existing binaries that use the previous
glfs_h_lookupat() function, the old symbol needs to stay available.

Verification that there are two versions of glfs_h_lookupat:

  $ objdump -T /usr/lib64/libgfapi.so.0 | grep -w glfs_h_lookupat
  0000000000015070 g    DF .text  000000000000021e  GFAPI_3.7.4 glfs_h_lookupat
  0000000000015290 g    DF .text  0000000000000008 (GFAPI_3.4.2) glfs_h_lookupat

Testing with a binary (based on anonymous_fd_read_write.c from ./tests/)
that was linked against the old library:

  $ objdump -T ./lookupat | grep -w glfs_h_lookupat
  0000000000000000      DF *UND*  0000000000000000  GFAPI_3.4.2 glfs_h_lookupat

Enable debugging for 'ld.so' so that we can check that the GFAPI_3.4.2
version of the symbol gets loaded:

  $ export LD_DEBUG_OUTPUT=lookupat.ld.log LD_DEBUG=all
  $ ./lookupat
  $ grep -w glfs_h_lookupat lookupat.ld.log.2543
  2543:     symbol=glfs_h_lookupat;  lookup in file=./lookupat [0]
  2543:     symbol=glfs_h_lookupat;  lookup in file=/lib64/libgfapi.so.0 [0]
  2543:     binding file ./lookupat [0] to /lib64/libgfapi.so.0 [0]: normal symbol `glfs_h_lookupat' [GFAPI_3.4.2]
