MXS-2694: Add support for COM_BINLOG_DUMP

a never-ending resultset.

Fix RWBackend state tracking with multi-result queries
...
If a query returned multiple resultsets and the connection was broken
between the resultsets, the backend would not know that parts of the
response were already sent. This is caused by the cyclic nature of the
state machine when multi-result responses are being processed.
To fix the problem, the result size is tracked to know how many bytes have
been sent to the client. This is a backport of the
MySQLProtocol::Result::size from 2.5(develop).

MXS-2582: Deep-copy PS buffers in RWBackend::write
...
Deep-copying prevents subsequent modifications done by the caller from
affecting the data that can be potentially stored in the write queue of
the backend's DCB.

Make packet boundary assertion less costly
...
mxs::Buffer::iterator is not a random-access iterator and hence will have
linear cost. This is too costly to do on every packet with even moderately
sized resultsets.

Handle trailing unexpected ERR packets
...
RWBackend did not expect that a resultset and an unexpected ERR packet
could be stored in the same buffer. This can happen for example if a
server shuts down immediately after the resultset is sent.

Add advance(int) to mxs::Buffer iterators
...
This makes iterating over packets in buffers faster while still
maintaining the requirements for forward iterators. Not using operator+=
makes it clear that this is not a random access iterator.

Remove useless templates from RWBackend functions
...
There's no need for templates as the code is only used with one
type. Changed the code to use std::advance as that might avoid a copy of
the iterator.

Move result start handling into separate function

The largest part of the code deals with the start of a response. Moving
this into a subfunction makes the function clearer as the switch statement
inside a switch statement is removed.

Simplify RWBackend result handling
...
By processing the packets one at a time, the reply state is updated
correctly regardless of how many packets are received. This removes the
need for the clunky code that used modutil_count_signal_packets to detect
the end of the result set.
