commit a9d558f144f106a3b1f5069d4eab37e636c59f09
Merge branch 'master' of ssh://vault.foobar.fi/srv/src/libreswan
documentation: minor edits in ipsec.conf.in
pluto: Removed IKE_ALG define - it could not be disabled
pluto: Removed KERNEL_ALG define - it could not be disabled
updated changes
pluto: Clarified kernel_alg_esp_auth_ok() calls

It's an "ugh" call, it returns err_t so returning NULL means
success, and non-NULL is the error string.
ipsec_xform.h: Add a comment to show we left out 1des on purpose
Merge branch 'master' of ssh://vault.foobar.fi/srv/src/libreswan

fix dist_cert special keys/certs and paths
testing - allow a "post" script to run after both I/R run scripts
complete, just before running final on both. Good for testing
whack after tunnel establishment.

They are used by placing commands in eastpost1.sh/westpost2.sh or
westpost1.sh/eastpost2.sh. The script with '1' will run before '2'
for order control.
testing: Converted the loopback/labeled ipsec testcases to KVM

They are still showing a problem of not being able to find the PSK
for localhost in the secrets file.
_stackmanager: Move iptables mangle rules to MAST only section

Also only try to clear when the mangle table is actually loaded.
Add support for IPv6 mangle tables
_stackmanager: modprobe for timeriomem-rng and tpm-rng at startup
MAST: Add support for IPv6 iptables mangle table in updown.mast
scripts: Don't load nat/mangle kernel modules just for listing (rhbz#954249)

If the tables are not loaded already, don't load them just to list
empty tables.
_stackmanager: fix shellscript syntax - line continuation must be marked
