This change is necessary to avoid frequent disconnections between client and server under load.
A disconnect-connect sequence is costly in terms of clean up and re-building of context,
self-heals etc. This value should be optimal for most use cases. Users requiring a lower
ping-timeout value need to configure it explicitly.

- st_dev is used for storing generation number of the inode in
inode_link and libgf_iattr_transform changes the st_dev to fake_fsid.
If inode_link is done after libgf_iattr_transform, the generation number
stored will be wrong and will result in ESTALE errors from server.

- glusterfs_glh_getxattr was implemented using libgf_client_lookup. Hence the
inode corresponding to the path on which getxattr was done was refed twice
- one during path_lookup and the other in libgf_client_lookup - but unrefed
only once.
- with inode generation number changes the inode returned by inode_link may
not be the same as the input argument. Hence the inode returned by
inode_link should be used, not the one returned in libgf_client_lookup_cbk.

- There can be a condition wherein,
1. the thread executing ib_verbs_recv_completion_proc (thr 1) stores the
buffer pointer and notifies the upper translators about a POLLIN event.
2. the thread waiting for events on socket (thr 2) calls transport_receive,
but in ib_verbs_receive it has not still read the data.
3. thr 1 receives work completion event for another work request and
overwrites the buffer pointer.
4. thr 2 reads from the new pointer there by missing the data stored in
buffer pointed by pointer which got overwritten.

BUG: 343 (Placeholder bug for adding volgen into rpm, bdb makefile changes, etc)
URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=343
The problem: If some files on the first subvolume disappeared
without leaving a trace in the entry changelog (this can happen,
for example, when an fsck has deleted files or when a hard drive
is replaced), those files would never be self-healed even though
they would be present on the second subvolume. This is because
readdir is sent only to the first subvolume, and since the files
don't appear in the directory listing, no lookup would ever be
sent on them.
This patch fixes this problem by doing a readdir on all the subvolumes
during the first opendir on a directory inode. If a discrepancy in the
contents is detected, entry self-heal in a special "force merge" mode
is triggered on that directory.
