Purpose This fixes the handling of global-db-lock in mod_sofia has configurable.

Overview As the Freeswitch use global DB locks to ensure a module will execute just one query at a time creates a bottleneck and it is required only for sqlite , not required for Mariadb or postgresql as it can handle multiple concurrent queries. To overcome this issue added and enabled the global-db-lock settings for mutex lock conditions in sofia_glue.c file.

Enhancements 1.To make the code backward compatibility added a new setting global-db-lock in suitable files to enable or disable mutex lock and unlock. 2.Added a new header for global-db-lock.

Problems faced Creates bottleneck

Changes done 1.Modified sofia_glue.c file mutex conditions with enabling global_db_lock settings. 2.Added a header for global-db-lock in mod_sofia.h.

this for sure should not be a config setting… this should come from api knowing if we need it or not based on different engines. also must ensure there isnt anything we’ve done that assumes ordering as a side effect of these locks
