[RELEASE] Released version 1.3.9 with the following changes :

    - modularized the polling mechanisms and use function pointers instead
      of macros at many places
    - implemented support for FreeBSD's kqueue() polling mechanism
    - fixed a warning on OpenBSD : MIN/MAX redefined
    - change socket registration order at startup to accomodate kqueue.
    - several makefile cleanups to support old shells
    - fix build with limits.h once for all
    - ev_epoll: do not rely on fd_sets anymore, use changes stacks instead.
    - fdtab now holds the results of polling
    - implemented support for speculative I/O processing with epoll()
    - remove useless calls to shutdown(SHUT_RD), resulting in small speed boost
    - auto-registering of pollers at load time
