The 'scudo' memory allocator set by the 'hardened' profile breaks some
services on 20.09.
The fix for NixOS unstable (https://github.com/NixOS/nixpkgs/pull/104052)
is ineffective on 20.09.
As a workaround, add a custom 'hardened' preset that uses the default allocator.
- Remove redundant option mainchainrpchost.
This option is already provided by bitcoind.
- Set a working default for rpcport and rpcuser.
Enables use without secure-node.
Going without the conditionals (like in secure-node.nix) adds
readability and doesn't reduce evaluation performance (in fact, it
even slightly improves performance due to implementation details
of mkIf).
To avoid errors, remove use of disabled services in secure-node.nix and
nix-bitcoin-webindex.nix.
Previously, systemd-status was broken for all users except root.
Use a 'default' deny policy, which is overridden for group 'proc'.
Add operator to group 'proc'.
Also, remove redundant XML boilerplate.
Mitigates a security issue that allows unprivileged users to read other
unprivileged user's processes' credentials from CGroup using `systemctl
status`.

hiddenService.
- Amends hardcoded lnd ip to lnd-cert
WARNING: Breaking changes for lnd cert. lnd-key and lnd-cert will have
to be deleted and redeployed.

network namespaces.
- Adds listen, rpclisten, and restlisten option to specify host on which
to listen on for peer, rpc and rest connections respectively

instead of lnd to bring in line with clightning.
WARNING: Breaking changes for Tor Hidden Service. Manual migration
necessary.
- Adds clightning to netns-isolation.services

enabled or not.
- Adds bitcoind to netns-isolation.services
- Adds rpcbind and rpcallowip options to allow using bitcoind with
network namespaces
- Adds bind option (defaults to localhost), used as target of hidden service
- Makes bitcoind-import-banlist run in netns
- Adds network namespace instantiation and routing architecture.
- netns-isolation disabled by default. Can be enabled with
configuration.nix FIXME.
- Uses mkMerge to toggle certain options for non netns and netns
systems.
- Adds security wrapper for netns-exec which allows operator to exec
with cap_sys_admin
- User can select the 169.254.N.0/24 addressblock netns's are created in.
- nix-bitcoin-services IpAddressAllow is amended with link-local
addresses
Remove the possible null value for bitcoind.prune and set prune = 0 in
bitcoind as a default. Remove prune = 0 in secure-node.nix and the
mkForce in configuration.nix (bitcoind.prune = lib.mkForce ).

In conjuction with secure-node.nix, this sets sane
RestrictAddressFamilies unless lnd is enabled. Before, we were
constantly exposing unnecessary Address Families, not just when lnd is
enabled.
However, zmqpub* must always be enabled for lnd, even when used
outside of secure-node.nix, so we make this change in the lnd module.
currently, nodeinfo has presets/secure-node.nix as a strict
dependency as it requires onion-chef and the 'operatorName' option.
and nix-bitcoin-webindex.nix has nodeinfo as a dependecy.
so don't add nodeinfo and webindex to modules.nix because they will fail on standalone use.
This fixes these flaws in `copy-root-authorized-keys`:
- When `.vbox-nixops-client-key` is missing, operator's authorized_keys
file is always appended to, growing the file indefinitely.
- Service is always added and not restricted to nixops-vbox deployments.
