Revert "FS-10304: [mod_callcenter] Prevent infinite logging when a stale queue member in found in the database"

This reverts commit 5d4ee9a8.

Conflicts:
	src/mod/languages/mod_lua/mod_lua_wrap.cpp

Clears SSL error state.

Updates tport_tls.c to clear the SSL error state after an error occurs.

OpenSSL puts errors into a queue that is kept in thread local storage.
In some cases, such as when SSL_ERROR_SSL is returned by SSL_get_errror(),
OpenSSL will queue multiple errors for a single event. When this occurs,
OpenSSL will report an error the next time I/O is performed if the queue
is not cleared first, which can result in TLS connections being torn down
prematurely.

In case of outbound_redirect_fatal=true none of the redirect variables are
set. This makes it impossible for ESL applications to extract any information
related to the "302 Moved Temporarily" reply.

Revert "FS-10299 [mod_callcenter] Removing global lock on all cc_execute_sql functions when executing database queries"

This reverts commit faf87feb.

FS-10304: [mod_callcenter] Prevent infinite logging when a stale queue member in found in the database

Having a member from a queue that is no longer found on the current system
causes infinite logging about skipping a member.

There is already cleanup code for abandoned calls in same function, but it can
never be reached for this case, because there is no queue.

If the queue is never found again in the system, the logging would continue
forever or until the stale record gets removed from the database.
