- In protocol/client, fdctx is accessed by two sets of procedures,
protocol_client_mark_fd_bad falls in one set whereas the other set consists of
all fops which receive fd as an argument. The way these fdctxs are got is
different in these two sets. While in the former set, fdctx is accessed
through conf->saved_fds, which is a list of fdctxs of fds representing
opened/created files. In the latter set, fdctxs are got directly from fd
through fd_ctx_get(). Now there can be race conditions between two threads
executing one procedure from these two sets. As an example let us consider
following scenario:
A flush operation is timed out and polling thread executing
protocol_client_mark_fd_bad, fuse thread executing client_release. This can
happen because, immediately a reply for flush is written to fuse, a release on
the same fd can be sent to glusterfs and the polling thread still might be
doing cleanup. Consider following set of events:
1. fuse thread does fd_ctx_get (fd).
2. polling thread gets the same fdctx but through conf->saved_fds.
3. Now both threads go ahead and does list_del (fdctx) and eventually free
fdctx.
In other situations the same set events might occur and the threads
executing fops other than flush in the second set might be accessing a
fdctx freed in protocol_client_mark_fd_bad.

BUG: 224 (Client hangs if none of the servers are up)

In client_open_cbk, client_opendir_cbk the list_add_tail macros were invoked with wrong
ordered arguments, causing the existing registered fd list to get unlinked from the
saved_fds list. The effects of this is far fetched - when transport disconnects, open
fds are no more marked bad as they are not reachable from the saved_fds list. After
reconnection, resumed access on this fd causes reference to invalid fds on the server.
It could appear in the form of 'unresolved fd' error, readdir happening on a file fd,
files reading from other files, etc.

Thhie change removes a huge inefficiency in file open
path where every open resulted in dictionary operations
in order to let the client maintain a list of fd_t's being
used over a particular client context.

This patch is a step towards giving compatibility between the versions of
GlusterFS. Now onwards, the protocol-version won't depend on release
versions. In general, multiple glusterfs versions can have common
protocol-version.

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.

from transport_connect() was EINPROGRES
This bug was racing between a CHILD_UP from poll thread resulting from the event_register() of the new socket called in fuse thread. CHILD_UP would sometimes overtake the CHILD_DOWN for EINPROGRESS. So replicate would receive CHILD_DOWN as the latest event. This resulted in self-heal not happening etc.
