For anchors, we need some sats sitting around in case we need to CPFP
a close.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: Config: `min-emergency-msat` setting for (currently experimental!) anchor channels, to keep funds in reserve for forced closes.
We disabled experimental support for opening non-zero-fee anchor
channels (though old nodes may still have such channels if they turned
that on!).
So we simply call this `experimental-anchors`, since this is the variant
which we expect to be used widely.

Changelog-EXPERIMENTAL: protocol: added support for zero-fee-htlc anchors (`option_anchors_zero_fee_htlc_tx`), using `--experimental-anchors`.
Currently only implemented for min-capacity-sat.

This obsoletes the use of --announce-addr-dns which I know Michael
didn't really like either.
Changelog-Deprecated: Config: `announce-addr-dns`; use `--bind-addr=dns:ADDR` for finer control.

This is a major cleanup to how we parse addresses.
1. parse_wireaddr now supports the "dns:" prefix to support dns records (type 5).
2. We are less reliant on separate_address_and_port() which gets confused by
that colon.
3. We explicitly test every possible address type we can get back from
parsing, and handle them appropriately.
We update the documentation to use the clearer HOSTNAME vs DNS prefixes now
we also have `dns:` as a prefix.
Changelog-Added: Config: `bind` can now take `dns:` prefix to advertize DNS records.

Turns out the two bcli replacements I checked (`sauron` and
`trustedcoin`) don't even implement this, and the multiplier makes
more sense in lightningd, especially as we move to bcli just providing
raw feerate estimates.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Since it's not spec-final yet (hell, it's not even properly specified
yet!) we need to put it behind an experimental flag.
Unfortunately, we don't have support for doing this in a plugin; a
plugin must present features before parsing options. So we need to do
it in core.

This switch was not doing anything useful anymore.
We deprecate it anyways to notify the user about the new switch.

The only time underscores aren't special in Markdown is when they appear
in preformatted text. We have gotten away with not escaping underscores
where an asterisk-enclosed span or the paragraph ends before the next
underscore appears, but this is fragile and bad practice. Conversely,
there are many places where we have not escaped underscores but needed
to.
Escape all underscores that do not appear in preformatted blocks or
preformatted spans and are not themselves delineating emphasized spans.
The changes in this commit are exactly the result of executing the
following Bash code:
```bash
e=':x;' # begin loop
e+='s/^' # anchor match at beginning of line
e+='(' # begin capturing subexpression
e+='(' # begin list of alternatives
e+='[^`_\\]|' # any mundane character, or
e+='`([^`\\]|\\.)*`|' # backtick-enclosed span, or
e+='\b_|_\b|' # underscore at boundary, or
e+='\\.' # backslash-escaped character
e+=')*' # any number of the preceding alternatives
e+=')' # end capturing subexpression
e+='\B_\B/\1\\_/;' # escape non-formatting underscore
e+='tx' # repeat loop if we escaped an underscore
escape_underscores=(
sed
# use extended regular expressions
-E
# skip over indented blocks (following an empty line)
-e '/^$/{:i;n;/^( {4,}|\t)/bi}'
# skip over preformatted blocks
-e '/^\s*```/,/^\s*```/{p;d}'
# skip over generated sections
-e '/GENERATE-FROM-SCHEMA-START/,/GENERATE-FROM-SCHEMA-END/{p;d}'
# escape underscores

This broke BTCPayServer, so revert. I originally (accidentally!)
implemented this such that it broadcast both DNS and IP entries, but
Michael reported earlier that they still don't propagage well, so
simply suppress them.

Changelog-Changeed: Config: `announce-addr-dns` needs to be set to *true* to put DNS names into node announcements, otherwise they are suppressed.
Changelog-Deprecated: Config: `announce-addr-dns` (currently defaults to `false`). This will default to `true` once enough of the network has upgraded to understand DNS entries.
It's more natural: we will eventually support dynamic config variables,
so this will be quite nice.

Changelog-Added: Plugins: `autoclean` can now delete old forwards, payments, and invoices automatically.
The old `experimental-accept-extra-tlv-types` is now `accept-htlc-tlv-types`.

Changelog-Added: Config: `accept-htlc-tlv-types` lets us accept unknown even HTLC TLV fields we would normally reject on parsing (was EXPERIMENTAL-only `experimental-accept-extra-tlv-types`).
This is a good sanity check that users understand that if they upgrade
to master mid-cycle they can't go back!

There are no definition lists in Markdown, and lists get mangled if
they follow immediately: they need a line between them.
So use bullets for options, and use an indent so the text gets in the
line below.

`lightningd` has an option --wallet that lets you supply a database dsn
string to connect to a sqlite3/postgres database that's hosted/stored
elsewhere.
This adds the `--bookkeeper-db` option which does the same, except for
the bookkeeping data for a node!
Note that the default is to go in the `lightning-dir` in a database
called `accounts.sqlite3`
It actually only sets the prefix for the lightningd core log messages;
the other logs have their own prefix.
Make it a real, process-wide prefix which actually goes in front of the timestamp.

ChangeLog-Added: With the `sqlite3://` scheme for `--wallet` option, you can now specify a second file path for real-time database backup by separating it from the main file path with a `:` character.
mrkd doesn't like non-ASCII characters in ubuntu:18.04, used for
