* cygwin.din: Add symbols for getrlimit' and setrlimit'.

Browse Source 
* exceptions.cc (stackdump): Avoid creating stackdump when
        `rlim_core' is 0.
        * resource.cc: New global variable `rlim_core'.
        (getrlimit): New function.
        (setrlimit): Ditto.
        include/cygwin/version.h: Bump minor API version to 32 due to
        adding `getrlimit' and `setrlimit'.
        include/sys/resource.h: Add defines, types and prototypes for
        `getrlimit' and `setrlimit'.
