4d5b9cae9c MXS-2593: Remove unnecessary hangups
The backend DCBs do not have to send hangups in the close protocol API
method. If the conditions for the hangup were true, the session was
already stopping meaning that the client DCB was already closed.

40f35618ad MXS-2562: Fix out-of-order error during COM_CHANGE_USER
If an error is generated while a COM_CHANGE_USER is being done, it would
always use the sequence number 1. To properly handle this case and send
the correct sequence number, the COM_CHANGE_USER progress needs to be
tracked at the session level.

The information needs to be shared between the backend and client
protocols as the final OK to the COM_CHANGE_USER, with the sequence number
3, is the one that the backend server returns. Only after this response
has been received and routed to the client can the COM_CHANGE_USER
processing stop.

0c19d1ea03 Fix debug assertion in mysql_backend

0f714e9ad4 MXS-2495 Cleanup GWBUF interface
All GWBUF macros that address a single link in a chain are now
simple wrappers for equivalent gwbuf_link-functions.

Next step is to drop the macros and replace their use with calls
to the functions.

70450ce881 MXS-2349: Add support for UNIX domain sockets
Added core functionality for UNIX domain sockets in servers. Currently the
address parameter accepts them both but a separate `socket` parameter is
needed.

7db87784ac Deliver hangups only to valid DCBs
If a DCB was closed and a hangup event was sent to it via
dcb_hangup_foreach shortly after it was closed, the DCB would still
receive it even if it was closed. To prevent this, events must only be
delivered to DCBs if they haven't been closed.

5b43940559 Track session state only when required
The protocol should not track the session state as the parsing is quite
expensive with the current code. This change is a workaround that enables
the parsing only when required. A proper way to handle this would be to do
all the response processing in one place thus avoiding the duplication of
work.

7fb2ae571b Improve blocked host error message
The error now explains how the problem can be mitigated by increasing
max_connect_errors on the backend server.

021d48f94c Log low-level reason and idle time on master failure
If the connection to the master is lost, knowing what type of an error
caused the call to handleError helps deduce what was the real reason for
it. Logging the idle time of the connection helps detect when the
wait_timeout of a connection is exceeded.

630165e52b Fix closing of pooled DCBs
DCBs can now have a null session pointer and if they do, they are in the
persistent pool. The no-null-session assertions are no longer valid but
with a reorganization of the pooling code to only use file descriptors,
the assertions can be added back.

7aaadfc550 MXS-2196: Fix dcb error flag assignment
The error flag was set before the function was called which caused the
function to never be used. As the core should handle the filtering of
multiple errors on the same DCB, the protocol modules should not check it.

692127a2cb MXS-2196: Remove the dummy session
As each connection now immediately gets a session the dummy session is no
longer required. The next step would be to combine parts of the session
and the client DCB into one entity. This would prevent the possibility of
a client DCB with no associated session. Backend DCBs are different as
they can move from one session to another when the persistent connection
pool is in use.
