Michael Widenius 4fe3425009 Added "pool-of-threads" handling (with libevent)
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)

To build libevent, type
$ ./configure && make
(If you got libevent from the subversion repository, you will
first need to run the included "autogen.sh" script in order to
generate the configure script.)
Install as root via
# make install
You can run the regression tests by
$ make verify
Before, reporting any problems, please run the regression tests.
To enable the low-level tracing build the library as:
CFLAGS=-DUSE_DEBUG ./configure [...]
