- thanks to Ioannis Aslanidis <iaslanidis@flumotion.com> for reporting.
- breakup the server_connection_cleanup into smaller procedures.
- do following operations in a single atomic operation.
1. conn->active_transports--
2. collecting pointer to lock table and all fds if there are no active transports
this will avoid any race conditions.

1. A page will be put on the inode waitq if the 'freshness' has to be verified with an fstat()
2. while the fstat is in transit, other calls (like lookup) can update ioc_inode->tv, resetting the freshness (page still on inode waitq)
3. Another read request on the same page, after the updated freshness, will wake up the page frames neglecting the fact that the page is also waiting on the inode (waiting for the fstat completion)
4. once the page's frames are woken, the page becomes elegible for purging and can get destroyed for various reasons, leaving a destroyed page pointer in the inode's waitq
5. fstat returns and hits the destroyed page pointer causing a crash
The fix is to all together disable cache hits when any page of the same inode is under validation. The otherwise cache hit will now be subjected to the ongoing validation by getting queued to the inode waitq.

Thanks to Krishna <krishna (at) gluster.com> for pointing this out.
When a unify self-heal of large directory (directory with lot of entries)
is done, the getdents_cbk used to fail because of new limit of buffer size
(128KB). Noticed that earlier it used to streach upto 4MB, hence the value
1024 worked fine. By reducing it to 512, noticed, we can fit in well within
128KB limit, and hence unify self-heal goes through.

This can happen when 'option export-statfs-size off' is given in
posix volume. Caused divide by 0 error.

When mandatory locks are enabled and a read/write
would block due to a lock and if the fd is opened
with O_NONBLOCK, return EAGAIN (previously EWOULDBLOCK).

- memory corruption was due to new members being added between allocation
of buffer for serializing xattr_req dictionary and dict_serialize of
xattr_req.

- sc_readlink wrongly returned strlen (link) + 1 when link was present in
cache.
- this fixes rt #828. Since fuse_readlink_cbk does link[op_ret] = '\0', there
was a memory corruption.

This patch makes the server pass back the transport pointer of the client. If the UUID matches, the client makes the local transport 'shortcut' with the remote transport (pointer received from server)
The shortcut simulates a socket queue. Instead of serialized messages going over the network and getting queued in the tcp socket queue, the messages get queued in a transport specific queue picked by a polling thread.

Metadata operations now lock only a single byte at offset
(LLONG_MAX - 1) instead of the whole file, to avoid contention
with writev().

This patch cleans up io-threads behaviour regarding the
range values that can be specified for min-threads
and max-threads. THe major change is that the min threads
have been reduced to 2 to signify that io-threads needs minimum
two threads for its operation, while keeping the default number of
threads at 16. The idea is to decouple the default thread count
from the minimum thread count.
Note to Avati:
This applies over Raghu's indentation and logging take-3 patch.
