This patch fixes below issues in gfapi lease code-path
* 'glfs_setfsleasid' should allow NULL input to be
   able to reset leaseid
* Applications should be allowed to (un)register for
  upcall notifications of type GLFS_EVENT_LEASE_RECALL
* APIs added to read contents of GLFS_EVENT_LEASE_RECALL
  argument which is of type "struct glfs_upcall_lease"

gfapi: various broken symbol versions

2018-05-11T14:36:50+00:00

lots of breakage in symbol versions:
  symbols added in 4.1 incorrectly, and
  symbols added in 4.1 but labeled 4.0.0, and
  symbols added in 3.13 incorrectly

Not noticed until someone tried to build 3.13.2 on FreeBSD 11.1,
despite the fact that we build on FreeBSD 10.3 IIRC, somehow the
3.13 errors aren't a build error there.

Note: in rereading the Ulrich Drepper write-up I noticed that when
a symbol version is changed, you are supposed to leave the old
symbol in its original section in addition to adding it to its new
section. Adding back those symbols to their original sections.

Revert "gfapi: return pre/post attributes from glfs_pread/pwrite"

2018-05-08T15:27:48+00:00

This reverts commit d01f7244e9d9f7e3ef84e0ba7b48ef1b1b09d809.

This is being reverted as the API signatures should adapt to a
statx like structure, and also all APIs that need to return
pre/post attrs are not complete.

As a result, instead of fixing up part of the APIs and then
refixing the same in a later release, removing these set of
fixes from the branch

Additionally fixed up posix-entry-ops.c which was using the
new syncop signature

gfapi : RECALL_LEASE implementation

2018-05-04T17:12:19+00:00

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
