If PAM is configured to read user-specified environment variables
and UseLogin=yes in sshd_config, then a hostile local user may
attack /bin/login via LD_PRELOAD or similar environment variables
set via PAM.

refactor canohost.c: move functions that cache results closer
to the places that use them (authn and session code). After this, no state is
cached in canohost.c

In preparation for some updates to external/openssh to make it work with
BoringSSL, this change updates the code to a recent version. The current
version (5.9p1) is coming up on four years old now.
* Confirmed that f5c67b478bef9992de9e9ec91ce10af4f6205e0d matches
OpenSSH 5.9p1 exactly (save for the removal of the scard
subdirectory).
* Downloaded openssh-6.8p1.tar.gz (SHA256:
3ff64ce73ee124480b5bf767b9830d7d3c03bbcb6abe716b78f0192c37ce160e)
and verified with PGP signature. (I've verified Damien's key in
person previously.)
* Applied changes between f5c67b478bef9992de9e9ec91ce10af4f6205e0d and
OpenSSH 5.9p1 to 6.8p1 and updated the build as best I can. The
ugliest change is probably the duplication of umac.c to umac128.c
because Android conditionally compiles that file twice. See the
comment in those files.

Replace <sys/param.h> with <limits.h> and other less
dirty headers where possible. Annotate <sys/param.h> lines with their
current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1,
LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of
MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution.
These are the files confirmed through binary verification. ok guenther,

move authfd.c and its tentacles to the new buffer/key
API; ok markus@

make internal handling of filename arguments of "none"
more consistent with ssh. "none" arguments are now replaced with NULL when
the configuration is finalised.
Simplifies checking later on (just need to test not-NULL rather than
that + strcmp) and cleans up some inconsistencies. ok markus@

Add support for Unix domain socket forwarding. A remote TCP port
may be forwarded to a local Unix domain socket and vice versa or
both ends may be a Unix domain socket. This is a reimplementation
of the streamlocal patches by William Ahern from:
http://www.25thandclement.com/~william/projects/streamlocal.html

This may require changes to other code, such as fastbootd, which relies on this
service. sshd is not currently, used, however, so this change will force any
such code to be changed.
