Some tests have strict requirements on the filesystem permissions
for certain files and directories. This adds a regress/check-perm
tool that copies the relevant logic from sshd to exactly test
the paths in question. This lets us skip tests when the local
filesystem doesn't conform to our expectations rather than
continuing and failing the test run.

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.

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.
rsa-sha2-512,rsa-sha2-256 cannot be selected explicitly
in *KeyTypes options yet. Remove them from the lists of algorithms for now.

since these pages now clearly tell folks to avoid v1,
normalise the docs from a v2 perspective (i.e. stop pointing out which bits
are v2 only);

va_start was added in 0f754e29dd, however
it has the wrong number of args and it's not usable in non-variadic
functions anyway so it breaks things (for example Solaris 2.6 as
reported by Tom G. Christensen).i ok djm@
Add a function to enable security-related malloc_options.

refactor activation of rekeying
This makes automatic rekeying internal to the packet code (previously
the server and client loops needed to assist). In doing to it makes
application of rekey limits more accurate by accounting for packets
about to be sent as well as packets queued during rekeying events
themselves.
Based on a patch from dtucker@ which was in turn based on a patch

Only check errno if read() has returned an error. EOF is
not an error. This fixes a problem where the mux master would sporadically
fail to notice that the client had exited. ok mikeb@ djm@
