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.
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.
Modify the NTMakefile rules for tests so that a failed test does
not prevent subsequent tests from being executed.

The library delay loads bcrypt.dll so that it can run on versions of
Windows older than Vista. Remove the compile time checks.

kadmin should not permit a modify that stores invalid keys into the
database. Accepting bad key data into the database will result in
errors when those keys are eventually used.
This change does not address the general case. It does address the
specific case of the kadmin client attempting to store the magic
bogus key since that is trivial to check for and can be unintentionally
returned to kadmind by a 1.6rc2 or prior client. This can happen when
a user has get privilege but lacks the new get-keys privilege.

Introduce kadm5_all_keys_are_bogus() and kadm5_some_keys_are_bogus()
which will be used in later changes.

krb5_get_credentials_with_flags() and krb5_get_creds() do not store
obtained TGTs if the KRB5_GC_NO_STORE flag is set.

In get_cred_kdc_capath_worker() if the credentials obtained by
get_cred_kdc_address() does not exactly match the requested service
principal discard them and return KRB5KC_ERR_S_PRINCIPAL_UNKNOWN.

Prior to this change _krb5_get_cred_kdc_any() would include TGTs obtained
via KDC referrals in the "*ret_tgts" array returned to the caller. The
caller typically stores these TGTs in the active credential cache.
However, referrals TGTs must not be cached or reused for any request
beyond the one it was issued for. The referral is for a specific service
principal and the resulting TGT could include service specific AuthData.
The referral might also direct the client along a transitive path that
is specific to this service and not applicable in the general case.
This change removes the *ret_tgts parameter from get_cred_kdc_referral()
so that the obtained TGTs are never returned to its caller. This also
prevents these TGTs from being used by any subsequent call to
get_cred_kdc_capath().

Prior to this change hdb_unseal_keys_kvno() could return successfully (0)
if the choice_HDB_extension_data_hist_keys extension was found but the
hist_keys list was empty. As a side effect callers would believe that the
provide hdb_entry keys were unsealed when they weren't. This could cause
the KDC or kadmin to report invalid key size errors.
If the extension is present and the history list is empty attempt to
unseal the provided hdb_entry using hdb_unseal_keys_mkey().

In gsskrb5_accept_delegated_token() it is wrong to store the delegated
credentials in the default ccache by default. When the caller does not
provide a target credential handle, we just do nothing and return success.
Test the return value of gsskrb5_accept_delegated_token() against
GSS_S_COMPLETE, rather than 0.
Delegated or other explicit credentials were mishandled, the code only
worked correctly when processing default credentials. In particular
this caused root's default credential cache to be accessed when accepting
delegated credentials in SSH:
ssh_gssapi_accept_ctx() ->
ssh_gssapi_getclient() ->
gss_inquire_cred_by_mech()
When /tmp/krb5cc_0 contained expired tickets, cascaded credentials
stopped working for non-root users!
