When looking for a ticket, use the capath codepath first when we know
the service's realm: because we might have local policy as to how to get
there.
Then, if that doesn't work, try referrals. (For now unconditionally.)
On Windows if the compiler and C RTL is >= 1400 then the rand_s()
function is available. rand_s() unlike rand() makes use of the
RtlGenRandom() API to produce a random number between 0 and UINT_MAX.
If rand_s() is not available or fails, fallback to rand().
One of the benefits of rand_s() is that no initialization is required
so it will provide random output even if rk_random_init() is not called.

gss_add_cred() with GSS_C_NO_CREDENTIAL as the input_cred_handle should
act like gss_acquire_cred() with desired_mechs containing just the
desired_mech.
This utility, inspired by the old SunOS 4.x intr(8) utility, will be
used to start daemons with --detach and a timeout, like this:
intr -t 5 kdc --detach || { echo failed to start kdc; exit 1 }
This will allow tests to stop having to sleep poll for "started" output
from the daemons they start, allowing them to run faster and to impose a
reasonable timeout on daemon startup.
The default timeout is 3 seconds.
Tests that start daemons have to "wait" for them to start.
This commit makes Heimdal daemons prep to detach (when requested) by
forking early, then having the child signal readiness to the parent when
the child really is ready. The parent exits only which the child is
ready. This means that tests will no longer need to wait for daemons.
However, tests will still need a pidfile or such so they can stop the
daemons.
Note that the --detach options should not be used on OS X from launchd,
only from tests.
