Subject: [PATCH] switch_core: Add capability to specify core-db-name in
 switch.conf.xml to have sqlite in a different location.  This is important
 for everyone with relatively 'high' sip registration since the addition of
 sip registration to the core require sqlite db to be moved to a faster
 location (Ramdisk for example). Useful for everyone who moved their sqlite db
 for sofia to ramdisk because of performance issue.
