cluster/distribute: If cached_subvol is down, return ENOTCONN in lookup

When we follow a linkfile, and the lookup returns a ENOTCONN error, return
the error, as the cached subvol is down, and lookup_everywhere wont succeed,
but actually ends up clearing the linkfile, and clearing the namespace.

cluster/afr: Link inode only on lookup

Problem:
When "gluster volume heal <volname> info is executed, crawl's
process_entry is not going to populate iatt structure so the
iatt's gfid will be empty. So inode_links are failing.

Fix:
inode_link should be done only after lookup i.e. when heal is
performed. So moved the inode_link related code to just after
the lookup which is triggered when self-heal is done.

Tests:
The testcase that gives this issue does not give the inode-link
failures anymore. glustershd heal, info commands are working as
expected.
Wrote basic automation tests for proactive-self-heal-daemon

afr: Modified book-keeping structures for entrylks

* There are upto 3 entry lockees that may be needed to perform
  entrylk'ing in posix dir-write operations.

* For eg, rmdir ("/a/b") needs to acquire locks on two entities,
  - entrylk ("/a", "b")
  - entrylk ("/a/b", null)

* Changed existing entrylk/rename/selfheal (entrylk) transactions
  to use the new book-keeping structures

* Fixed few issues in afr_trace_entry_lk{in,out} functions. Tracing is now
  aware of the new entry lockee structure.

Implementation notes:
* Changed 'cookie' sent in stack_wind to encode lockee_entity_no
  and subvol_no.

  cookie is a non-negative integer such that 0 <= cookie < replica_count,
  When more than one lock is being acquired across the subvolumes,
  cookie % replica_count gives the subvol_no
  cookie / replica_count gives the lockee_entity_no.
