I was wondering why TAGS was missing some functions, and finally
tracked it down: PRINTF_FMT() confuses etags if it's at the start
of a function, and it ignores the rest of the file.
So we put PRINTF_FMT at the end, but that doesn't work for
*definitions*, only *declarations*. So we remove it from definitions
and add gratuitous declarations in the few static places.1

Dynamic plugins were keeping fds open; they should not have these
at all anyway, but worse, they interfere with operation because
we don't notice they're closed.
The symptom was that shutdown of the test_plugin_slowinit and
test_plugin_command was 30 seconds (10 seconds grace to kill each daemon).

Dumb programs which have a --daemon option call fork() early. This is
terrible UX since startup errors get lost: the program exits with
"success" immediately then you discover via the logs that it didn't
start at all.
However, forking late introduced a heap of problems with changing
pids. Instead, fork early but keep stderr and the parent around: if
we fail early on, the parent fails with us. We release our parent
with an explicit action just before the main loop.

configurator failed under clang:
checking for #pragma omp and -fopenmp support... ccan/tools/configurator/configurator: Test for HAVE_OPENMP failed with 32512:
./configurator.out: error while loading shared libraries: libomp.so: cannot open shared object file: No such file or directory

These are generalized from our internal implementations.
The main difference is that 'struct json_escaped' is now 'struct
json_escape', so we replace that immediately.
The difference between lightningd's json-writing ringbuffer and the
more generic ccan/json_out is that the latter has a better API and
handles escaping transparently if something slips through (though
it does offer direct accessors so you can mess things up yourself!).

I decided to try a faster implementation, only to find our crc32c was
not correct! Ouch.
I removed the crc32c functions from ccan/crc, and added a new crc32c
module which has the Mark Adler x86-64-optimized variants.
We bump gossip_store version again, since csums have changed.

Brings in fixes for closing stderr in parent for pipecmd (oops!)
and configurator fix (which we don't need yet)
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Note that this changes the order of arguments to pipecmd to match the
documentation, so we fix all the callers!
Also make configure re-run when configurator changes.

This was from a different series, so I just cherry-picked it.
It adds ccan/membuf as a depenency of ccan/rbuf, though we don't use
it directly yet.

The visible changes are:
1. tal_len() is renamed to tal_bytelen() for clarity.
2. tal allocations *always* know their length.
3. tal/str routines always set the length to strlen() + 1.

structeq() is too dangerous: if a structure has padding, it can fail
silently.
The new ccan/structeq instead provides a macro to define foo_eq(),
which does the right thing in case of padding (which none of our
structures currently have anyway).
Upgrade ccan, and use it everywhere. Except run-peer-wire.c, which
is only testing code and can use raw memcmp(): valgrind will tell us
if padding exists.
Interestingly, we still declared short_channel_id_eq, even though
we didn't define it any more!

In particular, this gets some MacOS fixes from #1327.
It also includes a major intmap update which fixes corner cases in traversals,
and requires ccan/bitops.

This gives us a slew of -Wextra fixes (not all of them though!) but
we're actually doing it for the monotonic version of timers.
This breaks some stuff, so we fix that up next.
