Happy new year (Update copyright to 2016)

Give the possibility of the client to pass a factory

Don't use the specific translated name but use the macro for this

More const and moved the declaration of php_mysqlnd_scramble() to mysqlnd_auth.h

MNDR:
- move things out of mysqlnd_priv.h

MNDR:
- remove inclusion of uneeded headers

MNDR:
- better name for MYSQLND_PPEC - MYSQLND_PFC (protocol frame codec)

MNDR:
- rename MYSQLND_NET to MYSQLND_PPEC (protocol packet envelope codec).
PPEC does only the encoding and decoding to the protocol frame.

MNDR:
- moved networking code to mysqlnd_vio.c

MNDR:
- 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 abou

MNDR:
- 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.

MNDR:
- make the connection state a class

MNDR:
- make MYSQLND_ERROR_INFO a class

MDNR:
- make MYSQLND_UPSERT_STATUS more like an object that a simple structure
Still use macros to make updates simple

MDNR:
- Refactor the command factory. Let the factory be exchangeable.

MNDR:
- Inject the object factory

MNDR:
- remove static function and make it a method. The function doesn't need to
be in mysqlnd_ps.c as it doesn't use any resources anymore from it (it used
in the past)

MDNR:
- 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

MDNR:
- 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.

MNDR:
- Rename MYSQLND_PROTOCOL to MYSQLND_PROTOCOL_PAYLOAD_DECODER_FACTORY
- Rename other symbols related to MYSQLND_PROTOCOL accordingly

Use Zend MM to keep statistic of non-persistent connections (calloc/free->pecalloc/pefree)

cleanup the mod version macros, round 2

first shot remove TSRMLS_* things

remove fetches from mysqlnd
