5ac317e2b6 build: unify and fix endian tests
Unify the endian tests out of lib/ccan/wscript into wafsamba since
they're almost cross-compile friendly.
While at it fix them to be so by moving the preprocessor directives out
of main scope since that will fail.
And keep the WORDS_BIGENDIAN, HAVE_LITTLE_ENDIAN and HAVE_BIG_ENDIAN
defines separate because of different codebases.

0d9bb86293 build: find FILE_OFFSET_BITS via array
This makes cross-compiling happy, use a trick similar to autoconf's
AC_CHECK_SIZEOF macro.
Basically we make an array:

static int array[1 - 2 * !(((long int)(sizeof(off_t))) < 8)];

This gives -1 multiplied by the negation of the condition
(sizeof(off_t) < 8) cast to a long int.
So if the condition is true it gives array[(-1 * 0)] (remember the
condition is cast and negated) thus passing a build test with a 0-sized
array.
If it's false it gives array[(-1 * 1)] thus failing with a
negative-sized array.

8150f69dc4 ccan: make it a grouping library.
Andrew Bartlett pointed out that making CCAN a non-library will break
the build in a different way in future: when two separate private
libraries start using the same CCAN module, the symbol duplicate
detection will fire (since private libaries don't use any symbol
hiding).  That doesn't happen yet, but it will surely happen
eventually.

So, for now at least, we build as a private library again.  This
unfortunately means the top-level build creates a libccan.so, which
contains all the ccan modules whether you need them or not.  Given the
size of the library, I don't think this is a win.  But it's simple.

f3862b9171 ccan: we're subsystems, not a library.
Don't expose a libccan.so; it would produce clashes if someone else
does the same thing.  Unfortunately, if we just change it from a
SAMBA_LIBRARY to a SAMBA_SUBSYSTEM, it doesn't create a static library
as we'd like, but links all the object files in.  This means we get
many duplicates (eg. everyone gets a copy of tally, even though only
ntdb wants it).

So, the solution is twofold:
1) Make the ccan modules separate.
2) Make the ccan modules SAMBA_SUBSYSTEMs not SAMBA_LIBRARYs so we don't
   build shared libraries which we can't share.
3) Make the places which uses ccan explicit.

35a2d020a0 ccan: Only build ccan-failtest when we are in developer mode
From: Andrew Bartlett <abartlet@samba.org>

This code is incredibly useful, but is only needed in test code and may not be
perfectly portable.  It has compiled on all systems bar Solaris so far, but
rather than make it a requirement to build Samba, just keep it for development.

We weren't testing for this, and without it, typesafe_cb just casts
its function argument.  This is why I didn't get a warning when one of
my patches amended a function incorrectly.
