     [cipher.c cipher.h kex.c kex.h kexgexc.c]
     Add a special case for the DH group size for 3des-cbc, which has an
     effective strength much lower than the key size.  This causes problems
     with some cryptlib implementations, which don't support group sizes larger
     than 4k but also don't use the largest group size it does support as
     specified in the RFC.  Based on a patch from Petr Lautrbach at Redhat,
     reduced by me with input from Markus.  ok djm@ markus@

  - (djm) [configure.ac sandbox-capsicum.c sandbox-rlimit.c] Disable
    RLIMIT_NOFILE pseudo-sandbox on FreeBSD. In some configurations,
    libc will attempt to open additional file descriptors for crypto
    offload and crash if they cannot be opened.
 - (djm) [configure.ac] correct AC_DEFINE for previous.
