      Added "pool-of-threads" handling (with libevent) · 4fe34250
      Michael Widenius authored
      This is a backport of code from MySQL 6.0 with cleanups and extensions
      
      The following new options are supported
      configure options:
        --with-libevent                  ; Enable use of libevent, which is needed for pool of threads
      
      mysqld options:
      --thread-handling=pool-of-threads  ; Use a pool of threads to handle queries
      --thread-pool-size=#               ; Define how many threads should be created to handle all queries
      --extra-port=#                     ; Extra tcp port that uses the old one-thread-per-connection method
      --extra-max-connections=#          ; Number of connections to accept to 'extra-port'
      --test-ignore-wrong-options        ; Ignore setting an enum value to a wrong option (for mysql-test-run)
