baf72b7336 Fix sprintf modifiers all around the place. In most cases

the modifier

aa8f43fad9 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)

96e2651fa2 - revert revision 297277, break the builds (declaration must go 1st, size of void * and other known situations). Also Johannes, can you check that commit pls? Thought we were in bugs fixing only for 5.3 2010-04-01 20:21:50 +00:00

4941b23bcd 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.

3ff193c05e 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.

7496cc761e decouple the methods in MYSQLND_STMT from the data, 
needed to move to a new structure MYSQLND_STMT. Makes
the code cleaner and less error-prone.
Also fix PDO/MySQL which directly touch mysqlnd internals
instead of using API calls.

e50de7d982 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.

d20fdd603b 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.
