[OpenSIPS-Devel] [opensips] ASYNC_CHANGE_FD status + db engine async state parameter + db_virtual async (#715)

[Ionut Ionita]

This pull requests adds the following:

* added a new status - ASYNC_CHANGE_FD which allows changing the file descriptor in the reactor if something goes wrong in the resume function, such that you can do failover
* added a state parameter for database async query - database engines can now use a parameter to hold state between the async call (async_raw_query) and the async resume (async_raw_resume)
* adapted sipcapture and avpops to the new functionalities
* db_virtual can now use the async raw query functionality; since mysql is the only engine that supports this, it will be the only one supported
