cast_const() et. al. are supposed to be a constant expression, so you can do things like:
static char *p = cast_const(char *, (const char *)"hello");
Unfortunately, a cast to intptr_t and arithmetic makes suncc reject it as
a constant expression. We need the cast, because (1) the expression could be
a void *, so we can't just add to it, and (2) gcc complains with -Wcast-qual
without it.
So instead of adding BUILD_BUG_OR_ZERO, we use a ? :, which keeps everyone happy.

This imports licensing clarifications and updates as discussed on
samba-technical ("Subject: Re: ccan code breaks older build farm
systems").
In particular, the recent version have per-file license markers, and
some modules are relicenced more liberally: in particular Simo pointed
out that htable was GPL, and indirectly included by libtdb2, which
would have made that GPL as well.
