More check for valid MYSQLND_STMT before using it

Don't reference row_packet before checking if dereferencing is possible

Check if data is correct and initialize in a safe manner

Handle problems in the row_decoder, return type used to be void,
now it can return on problems.

Fix deallocation which can crash if the object is half-baken.
Happens during OOM.

Handle the situation when MYSQLND_PROTOCOL's methods return NULL.
mysqlnd should not crash but gracefully return with an error.

Gracefully handle OOM in mysqlnd_stmt_init. Release the handle
and return NULL.

Handle OOM in the code that generates PS Execute requests
to the server. Fixes crashes in case of OOM.

- Give possibility to overload mysqlnd_result_init().
- Always use conn->m->stmt_init instead of mysqlnd_stmt_init()

OOM fixes

OOM stability fixes

Handle OOM stemming from mysqlnd_result_init in the same
function and up the stack.

Remove unused parameter

Remove dead code and add possibility to fine tune the size of
a mempool (used for result sets).

- Fix copyrights

Recommit with an Windows build fix:
Fix inconsistencies
- memory allocated with spprintf, or likes, outside of mysqlnd's
allocator functions should not be freed by the mysqlnd's allocator
(a wrapper around emalloc/malloc).
- memory allocated by the mysqlnd's allocator should only be freed
by it.
- add a mode to track memory usage (malloc/free)

Fix a bug that a statement that is reset doesn't clean
the wire properly (as it is done when the statement is closed).
If there is more that one result sets returned from the PS
(like a call to SP that returns at least one RSet next to the
status rset) then the line was blocked. PS Multi-Res is not supported
in any libmysql from a GA-ed MySQL.

fix valgrind warning introduced with the latest patch. The memory
should be calloc-ed, not malloced, because the code that uses the
stmt storage needs that.

Also fix PDO/MySQL which directly touch mysqlnd internals
instead of using API calls.

allow persistency of PS

Pass tsrmls to all functions, which might need it in the future.
We are anyway breaking the internal ABI in 5.3.2 so this won't hurt
and make us prepared for the future.
