features/gfid-access: Fix entry operations

Problem:
When more than one aux-mounts are performing rmdir .gfid/<pargfid>/dir
simultaneously, then sometimes a hang is observed.  In gfid-access xlator When
virtual parent/inode are replaced with real parent/inode in loc, virtual
pargfid/gfid are not replaced with real pargfid/gfid respectively. Afr is using
parent_loc->gfids to order the entry locks. But parent_loc->gfid contains
random/virtual gfid generated by gfid-access xlator. Entrylk in client xlator
is using loc->inod->gfid for sending entrylk which has 'real' gfid. Because the
ordering is happening based on random gfids, One mount orders the locks as (L1,
L2) where as the other orders them as (L2, L1) leading to a dead-lock thus
a hang.

Fix:
Replace virtual pargfid/gfid with real pargfid/gfid when virtual-inodes are
replaced with real-inodes in loc.

Changes in statedump for stack, frame, locks

Internal call-stacks don't have lk-owner so it is a bit
difficult to confirm if a stack hung by comparing two
statedump files. This change prints call-stack, frame's
address. This should solve the comparison problem.

Lock times and log times don't have same timezone because
of which one has to manually convert the times for debugging
the issues. This change prints blocked, granted times also
in UTC.

Also fixed line truncation issue when client-unique-string
is big.

nfs: prevent assertion error with MOUNT over UDP

The MOUNT service over UDP runs in a separate thread. This thread does
not have the correct *THIS xlator set. *THIS points to the global (base)
xlator structure, but GF_CALLOC() requires it to be the NFS-xlator so
that assertions can get validated correctly.

This is solved by passing the NFS-xlator to the pthread function, and
setting the *THIS pointer explicitly in the new thread.

It seems that on occasion (needs further investigation) MOUNT over UDP
does not unregister itself. There can also be issues when the kernel NLM
implementation has been registered at portmap/rpcbind, so adding some
unregister procedures in the cleanup of the test-cases.
