cppmagic: Tweak testcase to work on older clang versions
clang version 3.4, for whatever reason, expands a few of the testcases
in cppmagic with slightly different whitespace from what we expect. Since
this was changed in later clang versions, it was probably a compiler bug,
but it turns out an extra space in the testcase can make it pass on clang
3.4 as well. This means we finally have clang builds working in Travis.

time: Change TIME_HAVE_MONOTONIC to be 0/1 rather than defined/undefined

ccanlint: Alter meaning of --summary option
--summary (used by make check) causes ccanlint to only ever print a
one-line summary of the results. When one of the tests fails, this isn't
very useful, because it doesn't say why it failed, or even which test
failed. This is particularly frustrating for failures in Travis CI builds
where it's not always straightforward to reproduce a similar enough build
environment to check the failure manually for a particular module.
--summary does have one purpose which is vital for make check, though: it
suppresses any attempt to interactively correct / improve the module
printing only results.
This changes --summary to only have the second effect, not the first. This
won't change the output in the case of passing modules, but will give more
useful information in the case of failing modules.

Makefile: First try at rewriting the ccan Makefile.
This change contains a simpler Makefile replacement with only 62 lines
of directives, 10 rules, and a 13 line support script for dependencies. The
build dependencies have been minimised and in some cases, corrected.
FEATURES:
* All targets can be built from a clean tree in one invocation.
* Parallel builds (tested with -j32 on 8 cores).
* Auto discovery of modules via _info files.
* Hopefully complete dependencies via a simplified generator.
* CFLAGS are respected and appended to compile flags.
* LINTFLAGS can be set to add check options (e.g. LINTFLAGS=-v).
* 'make clean' doesn't build anything before cleaning now.
* 'make quiet=1' builds quietly. 'make check quiet=1 -j N' produces
summary output like the former summary target.
* Non-phony test targets; tests are rebuilt only when dirty. Targets are:
check, fastcheck and fullcheck, the latter runs in non-summary mode.
* 'make <module>.[check|fastcheck|fullcheck]' runs tests for single modules.
TODO:
* Support Makefile-web and any other scattered targets
NOTES:
* The changes to dependency generation expose a circular
dependency between asort and order which is not fixed here.
* Tests always run their dependent tests. With -j support and
minimised rebuilds via tighter dependencies, its not worth avoiding.
* Some targets have been dropped as uneeded (e.g. distclean, tools).

Currently the functions to add data of various sizes/endianness have not

hex: Simplify hex_encode
The documentation for hex_encode indicates that it returns simply true or
false. The old implementation was returning the written length on success,
cast to boolean. This will elicit a warning under MSVC.
On further examination, there is no need to check/modify the length inside
the loop, since we can check it once before starting. As a result the code
can be simplified a bit.
A side affect of this change is that nothing will be written at all if the
length is incorrect, vs the previous code writing characters until the length
available is exhausted. I prefer the new semantics but YMMV.

sha256: Move 'bytes' to the end of sha256_ctx and make it a size_t
The code already assigns to/from bytes as a size_t, so make it
official (and better on platforms with a 32 bit size_t).
Moving bytes makes it act as a canary in the event that there is a rogue
write/off by one somewhere - since it ends up in the hash we are
more likely to detect this should we corrupt it. This also makes the
working buffer better aligned which can't hurt.
Also, initialise the buffer to zero while we are changing the initialisation
macro anyway. It costs little compared to the hashing overhead, should be
optimised away if redundant in most cases, and it removes a warning from both
gcc and clang about unititialised struct members.
