e15c418c4c Fix off by 1 problem. 
The problem was manifestated only with BIT columns and only when more than
one row was fetched. The problem was coming from the fact that in pre-7.0
times mysqlnd was using a no-copy optimization. This optimization kept the
strings (and also the BIT mask equivalents as strings) in the packet and the
zval referred to them. 7.0+ zvals cannot use no-copy and always copy. Because
of this the allocated memory for the packet was reduced by 1 by the person who
ported the driver, but the starting address of the bit area wasn't reduced.
Because of this the bit_area started at wrong address and the length decoded
wrong.

- less dereferencing in mysqlnd_ps . Dereference stmt->conn only once and
  use a stack variable. Also make the source cleaner.

80d59a3a36 MNDR:

Andrey Hristov
e9f3139f43 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.
