Wrap mysql_real_escape_string() in a function

Browse source 
Wrap mysql_real_escape_string() in a wrapper function db_escape_string()
to ease porting to other databases, and as another step to pulling more
of the database code into a central location.

This is a rebased version of a patch by elij submitted about half a year
ago.
