(15:27:11) joeyadams: ccanlint's handle_no_tests apparently has a bug.  It makes the test directory with 
0600 permissions, so it can't be used.  the x bit provides directory listing privilege
(15:27:25) joeyadams: this gives me Permission denied when I try to run it
(15:28:34) joeyadams: Changing the opcode to 0700 makes the creation of run.c work

Given the types used (uint32_t and uint64_t) many of the masks are unnecessary.
But mainly moving the bit extraction into separate inline functions means the
code is a bit clearer, and we only need to bracket one place.
But because these helpers shared the same names, I split the 32 and 
64-bit tests.

(1) Include ilog.h header first (checks that it doesn't need anything else)
(2) Include ilog.c (only api tests don't need this).

Makes the idempotent header check more liberal, and
specifically allows it to also recognize

#if !defined(someheader)
#define someheader (1)

or other similar variants.

Fixes the example module documentation ccanlint outputs. The
missing \n meant that it would not validate its own example as valid
documentation (with no explanation of why it was invalid... but that
would be a much larger patch).

We no longer use libccan for tests, but explicit object lists.  This 
will catch missing dependencies.  API tests *do* get the module object
linked in now.
In addition, makefiles now correctly rebuild when a dependency changes
(gcc's -MD here), and when _info.c changes.

Mutate whole triangles sometimes for better results.

Remove test that never ran properly anyway (still bug in current talloc 
testsuite).
