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.

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.
