Firstly, with Samba AD this looks a little weird because we log the same
message 5 times (once for every partition). If we log that we're doing
this to records in different partitions, hopefully someone with a little
Samba knowledge can figure out what's going on.
Secondly, the info about what partitions are actually changing might be
useful. E.g. if we hit a fatal error repacking the 3rd partition, and
the transaction doesn't abort properly, then it would be useful to know
what partitions were repacked and which ones weren't.
There doesn't appear to be a useful name for the partition
(ldb_kv->kv_ops->name() doesn't seem any more intelligible to a user),
so just log the first record that we update. We can use that to infer
the partition database).

This adds a direct conversion hook using libicu to perform NFC <-> NFD
conversion on UTF8 strings. The defined charset strings are "UTF8-NFC" and
"UTF8-NFD", to convert from one to the other the caller calls smb_iconv_open()
with the desired source and target charsets, eg
smb_iconv_open("UTF8-NFD", "UTF8-NFC");
for converting from NFC to NFD.

Avoid parenthesising an unsigned subtraction that can be negative and,
therefore, underflow. There is no need for the parentheses and
removing them results in an expression that is evaluated left-to-right
and can not underflow.
It isn't clear that the underflow matters. lp <= ls, so if (li - lp)
underflows then ls + (li - lp) will always overflow. This should
produce the correct answer. However, depending on this seems wrong.
