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.

[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@

sys/capability.h exists and cap_rights_limit is in libc. Fixes
build on FreeBSD9x which provides the header but not the libc
support.

Declare it as broken, and document FreeBSD's as the same. ok djm@

platform hardening options: include some long long int arithmatic
to detect missing support functions for -ftrapv in libgcc and
equivalents, actually test linking when -ftrapv is supplied and
set either both -pie/-fPIE or neither. feedback and ok dtucker@

Works around platforms such as FreeBSD 9.1 where it does not interop with

Cast the sizeof to socklen_t so it'll work even if the supplied len is
negative. Suggested by and ok djm, ok deraadt.

[canohost.c addrmatch.c]
Cast socklen_t when comparing to size_t and use socklen_t to iterate over
the ip options, both to prevent signed/unsigned comparison warnings.

optind) are defined in getopt.h already. Unfortunately they are defined as
"declspec(dllimport)" for historical reasons, because the GNU linker didn't
allow auto-import on PE/COFF targets way back when. The problem is the
dllexport attributes collide with the definitions in the various source
files in OpenSSH, which obviousy define the variables without
declspec(dllimport). The least intrusive way to get rid of these warnings
is to disable warnings for GCC compiler attributes when building on Cygwin.
