WL#5363: Thread Pool Service Interface
In order to allow thread schedulers to be dynamically loaded, it is necessary to make the following changes to the server: - Two new service interfaces - Modifications to InnoDB to inform the thread scheduler of state changes. - Changes to the VIO subsystem for checking if data is available on a socket. - Elimination of remains of the old thread pool implementation. The two new service interfaces introduces are: my_thread_scheduler A service interface to register a thread scheduler. thd_wait A service interface to inform thread scheduler that the thread is about to start waiting. In addition, the patch adds code that: - Add a call to thd_wait for table locks in mysys thd_lock.c by introducing a set function that can be used to set a callback to be used when waiting on a lock and resuming from waiting. - Calling the mysys set function from the server to set the callbacks correctly.
