This now works because we no longer call out to masterd or bitcoind to verify
the channels. It's also rather quick and silent so we can just process all
stored messages until we're done.

Messages from peers and messages from the gossip_store now have completely
different entrypoints, so we don't need to trace their origin around the message
handling code any longer.
This stores and reads the channel_announcements in the wrapping message which
allows us to store associated data with the raw channel_announcements.
The gossip_store applies channel_announcements directly but it also returns it,
and it gets discarded as a duplicate. In the next commit we'll have gossip_store
apply all changes, bypassing verification, so the duplication is only temporary.

Since we now store additional data along with the original messages they exceed
the length of the peer wire protocol messages.

If we have a non-empty file and the version doesn't match, then we truncate and
write our own version. If the file is empty we write our version and the
truncate becomes a no-op

Since we may want to extend the on-disk format by adding custom information we
may as well just go the extra mile and reuse the serialization primitives we
already have.

Moves any modifications based on an incoming gossip message into its own
function separate from the message verification. This allows us to skip
verification when reading messages from a trusted source, e.g., the
gossip_store, speeding up the gossip replay.

When we read from the gossip_store we set store=false so that we don't duplicate
messages in the store.

As proposed by @rustyrussell this makes it a bit easier to truncate and sync on
read errors.

Ee will be replaying gossip messages from the gossip_store soon. This means that
not all messages originate from a peer, so we move the queuing of error messages
up into the peer message handler.

* build: update INSTALL.md to include Fedora #1028
* doc: Add TOC to INSTALL.md
* doc: Use lower case for anchors in TOC and minor changes
- anchors require lower case
- TOC doesn't work with dots, using OS names
* doc: improving FreeBSD doc
- Add missing packages: gmp and asciidoc
- Include step gmake install
But only if we're actually going to change the feerate, otherwise we'd
log every time.

Naively, this would be 250 satoshi per sipa, but it's not since bitcoind's
fee calculation was not rewritten to deal with weight, but instead bolted
on using vbytes.
The resulting calculations made me cry; I dried my tears on the thorns
of BUILD_ASSERT (I know that makes no sense, but bear with me here as I'm
trying not to swear at my bitcoind colleagues right now).

This bug is a classic case of being lazy:
1. peer_accept_channel() allocated its return off the input message,
rather than taking an explicit allocation context. This concealed the
lifetime nature of the return.
2. The context for sanitize_error was the error itself, rather than the
more obvious tmpctx (connect_failed does not take).
The global tmpctx removes the "efficiency" excuse for grabbing a random
object to use as context, and is also nice and explicit.
