eb682c1bf4 Fix weight zero entries when ordering SRV RR results.
In lib/roken/resolve.c, we find rk_dns_srv_order() which re-orders
the results of an SRV RR lookup by the algorithm in RFC2782.  We
note that the algorithm doesn't behave according to the RFC w.r.t.
entries of weight zero.  We solve this by scaling out the remaining
weights by the number of zeros we find at a particular priority
level and acting like the zero weights have a weight of one.

44a1a2a273 Fix bias in ordering SRV RR results by weight.
In lib/roken/resolve.c, we find rk_dns_srv_order() which re-orders
the results of an SRV RR lookup by the algorithm in RFC2782.  We
fix a bias in the random weight sorting by changing the order of
operations when selecting rnd.  rnd should be a non-zero random
number less than the sum of the weights at a particular priority,
but zero was included as a legitimate output thus biasing the
selection process.  rk_random() % sum is still biased as a 32
bit int modulo a number which doesn't divide 2^32 does not have
a uniform distribution, but the bias should be small enough to
live with for our purposes here.

Commit efed5633 (r24759) prefixed some symbols with rk_, but
introduced 6 duplicate symbols in the version script (because the
rk_-prefixed versions of the symbols were already present).

0acef7729f roken: fix append_string "%.s" non-nul termination
It should be possible to pass a format string of "%.s" to permit
a non-nul terminated string to be used as input.  The test of remaining
precision and the test for NUL needs to be reversed to permit this
behavior to function correctly.

4cf66ae8e4 roken: use Win32 rand_s() for rk_random() when available
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.

b48bed5f42 Daemons detach atomically to avoid having to wait
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.

8485250989 roken: Add memset_s implementation
Add an implementation of memset_s to roken.

Some optimising compilers may remove the memset() instruction when it
is used immediately before a free, which defeats its purpose if the
intention is to zero memory before returning it to the heap or stack.

C11 added memset_s, provide a fallback in roken so that memset_s can
be used on all platforms.

017e502089 roken: win32 dlopen use LoadLibraryEx AltSearchPaths
LoadLibrary() is unable to load DLLs which are being loaded from
a global side by side assembly directory.   Instead, use

  LoadLibraryEx() with LOAD_WITH_ALTERED_SEARCH_PATH

This permits a DLL to be loaded from the WinSxs tree when a fully
qualified path is provided.

3e74e2e3bb Fix some DLL hell: use dladdr() to find plugin dir
Normally one would dlopen() a shared object's basename, not its absolute
path.  However, lib/krb5/plugin.c, in an effort to be zero-conf-ish,
wants to readdir() to find plugins to load, and in the process it ends
up defeating the RTLD's search-the-caller's-rpath.

This commit partially addresses this by allowing the use of $ORIGIN in
plugin_dir values and using them for the default (except on OS X).

This allows multiple Heimdal versions installed on the same host, but
with different plugin ABIs, to co-exist.  A step forward for doing make
check on hosts where Heimdal is installed.

For now we hardcode $ORIGIN/../lib/plugin/krb5 (linux, Solaris, *BSD),
or $ORIGIN (Windows; for assemblies objects need to be in the same
directory) and we eval $ORIGIN by using dladdr() (Linux, Solaris) or
GetModuleHandleEx() (Win32, via a dladdr() wrapper in libroken) to find
the path to libkrb5 whose dirname to use as $ORIGIN.  For Windows,
because we need the plugins to be in the same directory as libkrb5, we
require a prefix on plugin DLLs ("plugin_krb5_") to distinguish them
from other objects.

We should add a special token to mean "look in $ORIGIN, sure, but
dlopen() the plugin basenames only (so the RTLD can search the rpath)".

The Windows version of mkdir() does not share the same signature

on Windows but a future implementation could provide the required
