Better fix for bug #51347 mysqli_close / connection memory leak

Fixed bug #51347 mysqli_close / connection memory leak
Streams API registers every stream as resource, which lands then
in EG(regular_list), however doesn't clean that when the stream is
closed. At the end this is a para-leak. At the end of the script
all memory is cleaned, however this is a problem for long runnig
scripts that open connections. For every opened and closed connection
about 150 Bytes on 32bit and 250 Bytes on 64bit will be "lost",
according to memory_get_usage().

Fix compiler warning, copy&paste error

export some calls to init/deinit code outside of the module

improve the stats subsystem. Reduce the number of macro definitions
in half by smartly introducing 2 new macros. Make MYSQLND::stats a pointer
from being aggregated and add triggers.

add restart_psession and end_psession hooks

Change of way the packet objects are created/initialised
If the protocol gets changed, ever, we can decide at runtime
easily which protocol to use by instantiating the right protocol
object. But this is restricted to the structure of the packets, not
the flow.

Move this function to MYSQLND_NET as it works on the
php stream

Move compression and decompression code to separate functions
which can be overloaded on purpose.

refactoring : move more network related functions to
mysqlnd_net.c . Now communication is split on two levels:
- logical (functions send and receive)
- physical (functions network_read an

call free_contents in every case, in case something is not freed
by the calling code

move MYSQLND_NET code to a separate file.
mysqlnd_wireprotocol is about the protocol not the transport
layer
