add bridged timestamp and hangup_complete_with_xml=true to add xml_cdr to the body of hangup_complete events

mod_crd_sqlite entry limit and sqlite segfaults on triggers

mod_callcenter: Apparently, it by design that only 1 of the 2 leg can continue the dialplan.  So member are always A leg and agent are B leg.  If you want to continue after hangup a call for the agent like in uuid standby mode, use the transfer_after_bridge feature. Sample example usage is on the mod_callcenter wiki page.

switch_core_file: Fix a regression from earlier commit on some distro forcing warning on 'forced' return function value

sofia-lib: More Fix for -Wunused-but-set-variable required compiler. (Might need to be ported back to sofia)

mod_callcenter: Decided to take the easy way for portability for the moment.  We expect time_t to be an integral anyway in the core, so I'll expect the same here.  Should fix the problem with the partial change I did on i386 system

autoconf: Comment out the forced -Wunused-but-set-variable since not all module could be tested.  List of module I couldn't compile is in the comment.  Please all the different module maintainer check your module for this.  Thanks

Fix for -Wunused-but-set-variable required compiler. : mod_freetdm mod_avmd mod_cidlookup mod_ladspa mod_lcr mod_nibblebill mod_rss mod_vdm mod_dahdi_codec mod_skinny mod_cdr_pg_csv

sofia-lib: Fix for -Wunused-but-set-variable required compiler. (Might need to be ported back to sofia)

autoconf: Added the -Wunused-but-set-variable to the default compile to help avoid commiting more unused variable but set value.  Please report if you do have problem with it.

mod_callcenter: Quick changes to try to make it more multi platform friendly.  Still need to find the best way to convert a string to time_t that is multi platform.
