This:
- Allows `.*btc` amounts (without post-decimal)
- Avoids creating decimals when amount is 0 btc
- Corrects our handling of the suffixes (memeqstr would
sometimes return false because of null-termination)
Changelog-Fixed: We are now able to parse any amount string (XXXmsat, XX.XXXbtc, ..) we create.

It returns NULL, so you can simply `return fromwire_fail(...)`
if you want to return NULL in this case. Use that more.

We did this originally because these types are referred to in the bolts, and we
had no way of injecting the correct include lines into those. Now we do, so
there's less excuse for this.

I tried to fundchannel 0.01btc, and of course it wanted 8 decimals exactly.
If I can't get this right, it's probably a bad idea.
I still don't allow whole number of btc though, since that's probably a mistake
and you're not supposed to put that much in c-lightning yet :)

They're generally used pass-by-copy (unusual for C structs, but
convenient they're basically u64) and all possibly problematic
operations return WARN_UNUSED_RESULT bool to make you handle the
over/underflow cases.
The new #include in json.h means we bolt11.c sees the amount.h definition
of MSAT_PER_BTC, so delete its local version.
