Instead of testing (and priming) sudo with "true", prime with
"kill -0 $$" (just test signalling ourselves). If this fails,
we won't be able to kill the openvpn process we're going to
start later on -> thus, SKIP on failure.
This helps with misconfigured setups (especially on the buildbots)
that can correctly start openvpn but then not stop it later on -
leaving openvpn processes dangling around, requiring manual
intervention.

Previously one had to manually define correct values for the
EXPECT_IFCONFIG* variables based on what IPv4 and IPv6 addresses
the test VPN server handed out.
This was a tedious process especially with large number of tests,
as the IPs changed for every test client and for every test. With this
patch t_client.sh figures out the correct IP addresses using an
--up script and caches them to a separate file for later use.

This will check the OpenVPN log file if the process initialized
successfully.
It will check the log file for 30 seconds before aborting the test run.
This also has the advantage of starting the testing quicker if the
initialization goes faster than 10 seconds (which was the old sleep time).
The umask is also set to a more permissive mode to ensure the test
script is capable of reading the OpenVPN PID file, as that will be
created by root.

If the t_client.rc have PREFER_KSU=1 configured, t_client.sh
will check if you have a valid Kerberos ticket and if so it will
do all execution via ksu instead of sudo.
If PREFER_KSU is not set or a Kerberos ticket is not found, it
will fallback to the configured RUN_SUDO approach.
When using ksu it needs the full path to the program being executed,
so there is also additional code to find the full path of true and kill.
[ v2 - Remove $* from RUN_SUDO for ksu config. Old cruft which survived
last review before patch submission.
- Improve known state declaration of PREFER_KSU ]

As discussed with the development team, we should start moving away from
ciphers with a small block size. For OpenVPN in particular this means
moving away from 64-bit block ciphers, towards 128-bit block ciphers.
This patch makes a start with that by moving ciphers with a block
size < 128 bits to the bottom of the --show-ciphers output, and printing
a warning in the connection phase if such a cipher is used.
While touching this function, improve the output of --show-ciphers by
ordering the output alphabetically, and changing the output format
slightly.
[DS: Fixed C89 issues in patch, moving 'int nid' and 'size_t i' declaration
to begining of function instead of in the for-loops. This is also
required to not break building on stricter compiler setups where C99
must be enabled explicitly ]

Commit 40cb4cfc5d added infrastructure to write unit tests using
cmocka. This was implemented using a git submodule to fetch an
up-to-date cmocka test framework.
The issue which appeared was that 'make check' stopped working if
the cmocka submodule was not initialized and updated. As we do not
want this to be a hard depenency, this patch makes running these
unit tests conditional. If cmocka has not been initialized, skip
them or if it has been initialized all unit tests will be run.
[v2 - Also check if cmake is available, as cmocka depends on that
to be built ]

cmocka [1,2] is a testing framework for C. Adding unit test
capabilities to the openvpn repository will greatly ease the
task of writing correct code.
cmocka source code is added as git submodule in ./vendor. A
submodule approach has been chosen over a classical library
dependency because libcmocka is not available, or only
available in very old versions (e.g. on Ubuntu).
cmocka is build during 'make check' and installed in vendor/dist/.

Integration tests run by t_client.sh use sudo to run openvpn as root.
If the t_client.sh script is configured to use sudo then the user
must enter the password quickly because t_client assumes a startup
failure if openvpn does not start quick enough.
If the user is not quick enough, then the tests fails.
This change will refresh the sudo timestamp at the start of the script.

Our "make check" testsuite creates quite a bit of output which is
intended to help pinpointing the exact reason for failure - hidden by
default by automake 1.12 and up, which default to "parallel-tests" which
has no benefit for us. So, just set the automake option to revert to
the old behaviour.

sometimes changes while an OpenVPN test is running, resulting in spurious
failures in the "ifconfig/route must be restored identically after
