Previous patch on deprecation warnings broke use of old options due to function
call with too many arguments. This fixes the arguments so deprecation warnings
are properly traced while preserving old configuration options.
* htop: add some missing meters
* htop: replace individual options with 'settings'
Deprecate all options and introduce `settings` for setting htop configuration
values in Nix configuration.
Use `lib.htop` to provide `fields` and `modes` for easy access to htop's integer
configuration. And `leftMeters` and `rightMeters` functions for building the
separate `*_meters` and `*_meter_modes` attributes.
* htop: add release-notes 21.05 entry
* htop: improve deprecation warnings
Move default configuration into `settings` and make deprecated options default
to `null`. Print deprecation warnings for any option that is non-null --
i.e. only show warnings for explicitly specified deprecated options.
* htop: make self code owner of module
* release notes: fix invalid programs.htop xref
