s3:winbindd: pass a NULL ccache to kerberos_return_pac() for a MEMORY ccache
It means kerberos_return_pac() will use smb_krb5_cc_new_unique_memory().
...
Before that commit cc was never NULL as generate_krb5_ccache()
returned "MEMORY:winbindd_pam_ccache" as fallback.
So we called ads_kdestroy("MEMORY:winbindd_pam_ccache").
Now we have cc == NULL if user_ccache_file == NULL.
and kerberos_return_pac() uses smb_krb5_cc_new_unique_memory()
and krb5_cc_destroy() internally.
It means unless user_ccache_file != NULL we should not
call ads_kdestroy(cc) as cc is NULL and means we would destroy
any global default krb5 ccache.

Rather than probing for icu-i18n, icu-uc, and icudata libraries
separately, only probe for icu-i18n, and icu-uc, as direct dependencies
This avoids overlinking with icudata, and allows the package

When checking for shared libraries, only name the target library

Once the library is confirmed by CHECK_LIB, append the library if

This avoids a memcpy, and level 3 debug verbosity from

In other places we have something like `|| in->data[1] != '-'`, but
that is not useful here -- the value is either a string SID, or a

want to get messages about.

If two strings are invalid UTF-8, the string is first compared with
memcmp(), which compares as unsigned char.
If the strings are of different lengths and one is a substring of the
other, the memcmp() returns 0 and a second comparison is made which
assumes the next character in the shorter string is '\0' -- but this
comparison was done using SIGNED chars (on most systems). That leads
to non-transitive comparisons.
Consider the strings {"a\xff", "a", "ab\xff"} under that system.
"a\xff" < "a", because (char)0xff == -1.
"ab\xff" > "a", because 'b' == 98.
"ab\xff" < "a\xff", because memcmp("ab\xff", "a\xff", 2) avoiding the
signed char tiebreaker.
(Before c49c48afe0, the final character
might br arbitrarily cast into another character -- in latin-1, for
example, the 0xff here would have been seen as 'ÿ', which would be
uppercased to 'Ÿ', which is U+0178, which would be truncated to
'\x78', a positive char.
On the other hand e.g. 0xfe, 'þ', would have mapped to 0xde, 'Þ',
remaining negative).

This is unused because it does things badly, by just guessing and
not allowing valid sids that start with "s-". All the places that used
to use it were calling ldif_read_objectSid() or similar which correctly
check for string SIDs by actually trying to parse them. That begins
with looking for the "S-"/"s-", so this shortcut is not saving any real
work.

9 hex-digit subauths like '0xABCDef123' will not fit in 32 bits, so
should be rejected on parsing.
In other situations, such as defaultSecurityDescriptor, overflowing
SID subauths on Windows will saturate to 0xffffffff, resulting in a
valid but probably meaningless SID. It is possible that in previous
testing we saw that here, but it is more likely I got confused. In any
case, now I see them being rejected, and that is good.

S-1-5-32-545 (DOMAIN_ALIAS_RID_USERS) is surely going to exist,

That changes some of the assertions, making some NO_SUCH_OBJECTs
