Summary: MySQL Prepared Statements

Initial Comment:
Hi

file attached introduce MySQL Prepared Statemets API using in mysql module.
"Prepared execution is faster than direct execution for statements executed more than once, primarily because the query is parsed only once."
So I hope it can help OpenSER to be more quickly on SELECT/INSERT/UPDATE when it using (MySQL) DB backend.

To compile this API support you can define new make variable MYSQL_USE_PREPARED_STMT (or simply add it into Makefile) and run make/gmake.

This patch build for 1.2.0
I test it on my openser-1.2.0 and it works fine but more tests needed.
I will try to make code clear ASAP.

Thanks.

Hello Victor,

according to the mysql documentation, prepared statements are available
starting from version 4.1. This should be ok, as most of the distribution
ships at least 4.1 now. Are there any stabilty problems with 4.1 with this
feature? What version do you use?

I'll take next week a closer look to your patch.

Henning
