When doing a CTDB standalone build we don't want to use dynconfig,
since this introduces a lot of unwanted complexity. To avoid this,
either:
* charset needs to be nobbled to avoid loading the case tables, since
this depends on dynconfig; or
* charset needs to be avoid completely, so some functions need to be
replaced with their ASCII counterparts.
The 2nd options seems more honest and less error-prone.

samba-util depends on Samba-specific code. Exclude this code from
samba-util-core. When told to, via SAMBA_UTIL_CORE_ONLY, only build
samba-util-core and dependencies. When SAMBA_UTIL_CORE_ONLY is not
defined then the behaviour should be unchanged.
Standalone builds of CTDB will be done against samba-util-core to
avoid pulling in Samba-specific code.
An alternative would be to remove the Samba-dependent code from
samba-util. However, some of it is used by OpenChange.

The include files added to xfile.h are already included
unconditionally elsewhere (replace.h, samba_util.h, ...) so Samba
can't be built without them.
To minimise dependencies, only include specific util headers instead
of samba_util.h.

This is part of an attempt to untangle charset from util.c.
Most of this was moved from util_str.c in commit
55903e6f91. next_token() was moved from
charset to util.c in commit 4be643d4ce
so that it would be alongside next_token_talloc().
Now that util_str.c is in shared lib/util it is no longer necessary to
have these in util.c.

This function depends on genrand.c, which depends on lib/crypto. This
way the other IDR tree code can be used without lib/crypto.
While doing this, create idtree.h and idtree_random.h and clean up the

Compiling utilities with includes.h is confusing because includes.h
could come from source3, source4 or ctdb. Utilities should be
independent of such things.
Add a minimal set of fined-grained includes that attempts to avoid the
catch-all samba_util.h. A comment indicates what is used from
samba_util.h so that future clean-ups are easier.

This makes us fallback to strcasecmp early if any INVALID_CODEPOINT
appears. Without this patch we just continue to compare if both strings
happen to have an INVALID_CODEPOINT in the same spot.

When either string has a bad conversion, we fall back to
doing raw ascii byte comparisons using strcasecmp(). This
is wrong - we should fall back to strncasecmp.
The problem is we've already stepped past the character
that failed the conversion, so we're not re-testing those
characters for comparison. This can have the effect of
causing strncasecmp_m_handle() to report that two strings
are identical when they are not, if the failed conversion
takes place at the end of the string.
The correct behavior is to step back to the point of
the string(s) that failed the conversion, and continue
the test from there.
This is a litle trickier than the previous fix, as
it requires converting the incoming n variable from
remaining characters to compare to remaining bytes to
compare.
As bytes are always the smallest character size
(1 byte) then it's safe to convert the remaining
characters to check by decrementing the source string
by the last character length (in bytes) and incrementing
the remaining bytes to scan by the same value, then
calling strncasecmp() with the stepped back strings
remaining.
