[svn-r2815]

Purpose:
    Bugfix
Description:
    Detect whether the 'struct socklen_t' type is defined in the
    system include header files.
Solution:
    Added an AC_TRY_COMPILE test for 'struct socklen_t' to the configure
    script. This test is only executed if the Stream VFD is configured.
    Also added detection of <sys/types.h> and <sys/socket.h> system
    header files.
Platforms tested:
    Solaris 2.6 and 2.7
    IRIX64
    Linux
    Windows NT (command line configure with gcc and cl)
