This avoids overwriting the ones in git, and generally makes things neater.
We have convenience headers wire/peer_wire.h and wire/onion_wire.h to
avoid most #ifdefs: simply include those.

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.

We need the timestamp for channel_announcement, but this is simplified
because MCP always follows the channel_announcement by a channel_update.

Initialize infd to STDIN_FILENO if the input file argument is missing.

Save some overhead, plus gets us ready for giving subdaemons direct
store access. This is the first time we *upgrade* the gossip_store,
rather than just discarding.
The downside is that we need to add an extra message after each
channel_announcement, containing the channel capacity.

[devtools/create-gossipstore.c:153]: (error) Uninitialized variable: scidsats
scidsats access is gated by csvfile, which means this warning is a false
positive. However, it's cleaner to gate scidsts on itself, rather than
the cmdline option which caused it to be populated, so do that.

added sanity check to make sure scid of csv is the same as scid in gossip.
Revised style, mem allocation, and error checks
