[PATCH] Sqlite DB Pool

Hi,

I've made this small patch that fixes a couple of things on the Sqlite  
implementation:

* Sqlite2's [sqlite-connection] group was missing from cfg.def, though  
dbpool_sqlite.c and all the hooks were in place. This patch adds the  
missing section.
* This patch adds a "lock-timeout" configuration option to both sqlite  
connection groups, where a value in milliseconds can be specified.  
That value controls the time sqlite waits before throwing a lock  
("busy") error. This could be an issue because sqlite locks at the  
database level (yuk!), and this can surely be a problem under moderate  
load (I wouldn't recommend sqlite for heavy traffic at all). If not  
set the default behaviour is maintained, so nothing's broken ;)

BTW, my long-term goal is to have on Sqlbox the same DB capabilities  
as Kannel have (Sqlbox only supports MySql and Postgres and _maybe_ MS  
SQL). I'm making good progress with sqlite so far, and this patches  
aim to complete the Kannel support to make it practical to use the DB  
pool with Sqlbox.

MS SQL by Ct-Lib is supposed to be working, though is not supported at  
Kannel afaik (I'll try to port the code to Kannel so it can be linked  
from gwlib as the rest does when I have some spare time).
