4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

6a26b0c18d gossipd: increase randomness in route selection.
We have a seed, which is for (future!) unit testing consistency.  This
makes it change every time, so our pay_direct_test is more useful.

I tried restarting the noed around the loop, but it tended to fail
rebinding to the same port for some reason?

8375857116 common: absorb remaining files from daemon/
Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':',  not '/' too).
