ldb:utf8: ldb_ascii_toupper() avoids real toupper()

If a non-lowercase ASCII character has an uppercase counterpart in
some locale, toupper() will convert it to an int codepoint. Probably
that codepoint is too big to fit in our char return type, so we would
truncate it to 8 bit. So it becomes an arbitrary mapping.

It would also behave strangely with a byte with the top bit set, say
0xE2. If char is unsigned on this system, that is 'â', which
uppercases to 'Â', with the codepoint 0xC2. That seems fine in
isolation, but remember this is ldb_utf8.c, and that byte was not a
codepoint but a piece of a long utf-8 encoding. In the more likely
case where char is signed, toupper() is being passed a negative
number, the result of which is undefined.

ldb-samba: ldif-handlers: make ldif_comparison_objectSid() accurate

This function compares blobs that might be SID strings or might be SID
structures. Until now, if they were both (seemingly) strings, they were
compared as strings, otherwise if either was a string it was converted to
a structure blob, then the blobs were compared. This had two big problems:

1. There is variety in the way a SID can be stringified. For example,
   "s-1-02-3" means the same SID as "S-1-2-3", but those wouldn't compare
   equal.

2. SID comparison was crazily non-transitive. Consider the three values
     a = "S-1-2-3-4-5",
     b = "S-1-9-1",
     c = SID("S-1-11-1"), where c is a struct and the others are string.

   then we had,
     a < b, because the 5th character '2' < '9'.
     a > c, because when converted to a structure, the number of sub-auths
            is the first varying byte. a has 3, c has 0.
     b < c, because after the sub-auth count comes the id_auth value
            (big-endian, which doesn't matter in this case).

That made the function unreliable for sorting, AND for simple equality
tests. Also it leaked.

ctdb-scripts: Do not de-duplicate the interfaces list

Using xargs with sort -u to de-duplicate this list was my idea and
causes a couple of things to go wrong.  The use of xargs causes
double-quotes to be lost.  The resulting $public_ifaces value also
contains newlines.  The newlines could be removed with an additional
xargs at the end of the pipeline... but that would add an extra level
of quote stripping.

I have unsuccessfully tried to find an alternative, but still elegant,
command pipeline that de-duplicates the list, while maintaining
quoting.

So, just drop the de-duplication.

This might make interface_ifindex_exists_with_options() slightly less
efficient.  However, that function walks the whole list, only
terminating early when a match is found on both interface and options,
so at least it will be correct.

Include an extra testcase.
