39f303b1f3 fix sandbox on OSX Lion 
sshd was failing with:

ssh_sandbox_child: sandbox_init: dlopen(/usr/lib/libsandbox.1.dylib, 261):cw
  image not found [preauth]

caused by chroot before sandboxing. Avoid by explicitly linking libsandbox
to sshd. Spotted by Darren.

907091acb1 Make Solaris privs code build on older systems. 
Not all systems with Solaris privs have priv_basicset so factor that
out and provide backward compatibility code.  Similarly, not all have
PRIV_NET_ACCESS so wrap that in #ifdef.  Based on code from
alex at cooperi.net and djm@ with help from carson at taltos.org and
wieland at purdue.edu.

d3e2aee414 Check if realpath works on nonexistent files. 
On some platforms the native realpath doesn't work with non-existent
files (this is actually specified in some versions of POSIX), however
the sftp spec says its realpath with "canonicalize any given path name".
On those platforms, use realpath from the compat library.

In addition, when compiling with -DFORTIFY_SOURCE, glibc redefines
the realpath symbol to the checked version, so redefine ours to
something else so we pick up the compat version we want.

408f4c2ad4 Look for '${host}-ar' before 'ar'. 
This changes configure.ac to look for '${host}-ar' as set by
AC_CANONICAL_HOST before looking for the unprefixed 'ar'.
Useful when cross-compiling when all your binutils are prefixed.

Patch from moben at exherbo org via astrand at lysator liu se and
bz#2352.

e50e8c97a9 Add null declaration of AI_NUMERICINFO. 
Some platforms (older FreeBSD and DragonFly versions) do have
getaddrinfo() but do not have AI_NUMERICINFO. so define it to zero
in those cases.

72ef7c148c support --without-openssl at configure time 
Disables and removes dependency on OpenSSL. Many features don't
work and the set of crypto options is greatly restricted. This
will only work on system with native arc4random or /dev/urandom.

Considered highly experimental for now.

3d673d103b - (djm) [openbsd-compat/explicit_bzero.c] implement explicit_bzero() 
using memset_s() where possible; improve fallback to indirect bzero
