- split MYSQLND_NET into MYSQLND_NET and MYSQLND_VIO
MYSQLND_NET is above MYSQLND_VIO. _NET takes care of protocol packet
counting (even with compressed), while VIO is just about the network
(or in case of windows, non-network, but PIPE) transport.
- removed init() method from mysqlnd_conn_data and moved the initialization
to the object factory->get_connection(). Now it is unified as with the prepared
statement which doesn't have any init() method
- the protocol decoder factory now takes connection as parameter at creation and
thus there is no need to pass the connection as parameter when calling the read
or the write method of a packet.
- saved the protocol payload decoder factory as pointer in every packet (read/write)
so the connection doesn't need to be passed on every call of read/write (dependency
has been already injected at creation). This will alow to move protocol specific
code from MYSQLND_NET (send_ex()) to make MYSQLND_NET leaner and free from protocol
stuff.
implies more memory copy. The old method is still available and can be used.
It stays as default. Choosing the method is through a flag to mysqli_query()/mysqli_real_query()
New mode can be forced with an INI setting, for all extensions that support this mode
(ext/mysql and mysqli, because PDO due to it's architecture can't support it)
The setting is mysqlnd.fetch_data_copy=[0|1]
methods for the handle and the data object.
Add auxiliary functions to work with the new methods.
Add possibility to clone a connection object - shadow copy.
