Due to missing curly braces we end up calling the callback
function even when state is GLFD_CLOSE. This patch adds the
curly braces so both the log and actual callback is skipped.

Right now there are two types of upcalls
* poll method
* registering callback

But callback can be registered per fs and same callback fn shall be used
for any lease recall with object handle as argument as done for cache
invalidation.

TODO: RECALL LEASE for each glfd (for future reference)
 (may be needed fo Samba as they do not deal with
  object handles.

    In case of RECALL_LEASE, we could associate separate
     cbk function for each glfd either by
       - extending pub_glfs_lease to accept new args (recall_cbk_fn, cookie)
       - or by defining new API "glfs_register_recall_cbk_fn (glfd, recall_cbk_fn, cookie)
       . In such cases, flag it and instead of calling below upcall functions, define
        a new one to go through the glfd list and invoke each of theirs recall_cbk_fn.

Plus added following as well
* passed lease id to dict in required arguments
* added flag check in pub_glfs_open

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.

duplicatation of exported functions in gfapi.map. Only the newest one
is needed. Both the legacy and current symbols are exported.

glfs_io_cbk34 typedef should not be in a public header file. The old
application was compiled with the original glfs_io_cbk. Outside of
libgfapi, nothing now uses/needs this old typedef, move it into the
C file that needs it.

Similarly glfs_realpath34() decl should not be in glfs.h. Period. Old
applications were compiled with the then glfs_realpath() decl and
linked with glfs_realpath@@GFAPI_3_4.0. New applications should only
call glfs_realpath() and it will be linked to the new/current
glfs_realpath().

Problem: TLS verification fails while using intermediate CA
         if mgmt SSL is enabled.

Solution: There are two main issue of TLS verification failing
          1) not calling ssl_api to set cert_depth
          2) The current code does not allow to set certificate depth
             while MGMT SSL is enabled.
          After apply this patch to set certificate depth user
          need to set parameter option transport.socket.ssl-cert-depth <depth>
          in /var/lib/glusterd/secure_acccess instead to set in
          /etc/glusterfs/glusterd.vol. At the time of set secure_mgmt in ctx
          we will check the value of cert-depth and save the value of cert-depth
          in ctx.If user does not provide any value in cert-depth in that case
          it will consider default value is 1

Clients will request for a list of volfile servers from glusterd2 by
setting a (optional) flag in GETSPEC RPC call. glusterd2 will check for
the presence of this flag and accordingly return a list of glusterd2
servers in GETSPEC RPC reply. Currently, this list of servers returned
only contains servers which have bricks belonging to the volume.
