- Due to commit fe95cb2e (MDEV-16125),
InnoDB master thread does not need to call srv_resume_thread()
and therefore there is no need to wake up the thread.
Due to the above patch, InnoDB should remove the following dead code.

srv_check_activity(): Makes the parameter as in,out and returns the
recent activity value

innobase_active_small(): Removed

srv_active_wake_master_thread(): Removed

srv_wake_master_thread(): Removed

srv_active_wake_master_thread_low(): Removed

Simplify srv_master_thread() and remove switch cases, added the assert.

Replace srv_wake_master_thread() with srv_inc_activity_count()

INNOBASE_WAKE_INTERVAL: Removed
