external/openssh: update to 6.8p1.
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.
