Joshua Colp ce20eaa076 AST-2014-014: Fix race condition where channels may get stuck in ConfBridge under load. ...

Under load it was possible for the bridging API, and thus ConfBridge, to get
channels that may have hung up stuck in it. This is because handling of state
transitions for a bridged channel within a bridge was not protected and simply
set the new state without regard to the existing state. If the existing state
had been hung up this would get overwritten.

This change adds locking to protect changing of the state and also
takes into consideration the existing state.

We have faced situation when using CDR and CEL by sqlite3 modules. With system having high load (~100 concurrent calls created by sipp) we found many cdr and cel records missed. There is special finction in sqlite3, that make able to fix this situation - sqlite3_wait_timeout, that also can replace awful code cdr_sqlite3 ad cel_sqlite3 modules. Also this function can be used for aastdb and res_config_sqlite3 to avoid missed writes to sqlite db.
