* Also adds info messages for scanning.

Tidies up silent vs quiet vs verbose by adding logLevel as an option.

* Notes that we need to consolidate all the various CompilerOptions
  interfaces before they get too much further out of hand.
* Cleans up a couple of other minor TODO items.

In order to match existing behaviour with the legacy KeymanWeb compiler,
we should use quoted numbers for row ids. This behaviour can probably be
changed over to the new model in the future, but for now this prevents
unit tests from causing us grief.

feat(developer): Rewrite of KeymanWeb compiler in Typescript

Co-authored-by: Joshua Horton <joshua_horton@sil.org>

auto: increment master version to 17.0.121

fix(android/engine): Re-enable KMManager tests

fix(linux): Fix title of reference page and links

chore(linux): Move some files to keyman-config

chore(core): look for emcc.py, not emcc

auto: increment master version to 17.0.120

Fixes help.keyman.com#725

This extracts common code in a separate function.

chore(linux): Fix lintian warnings

chore(developer): ensure kmcmplib messages are all UTF-8

Relates to #8913.

auto: increment master version to 17.0.119

- add rudimentary man page for keyman-system-service
- remove hashbang for bash completion files
- reword description for keyman-system-service

This fixes these lintian warnings:
keyman-system-service: description-is-pkg-name Keyman system service
keyman: bash-completion-with-hashbang /usr/bin/env bash
        [usr/share/bash-completion/completions/km-config:1]
keyman-system-service: no-manual-page
        [usr/libexec/keyman-system-service]

Some of the configuration files are useful for other distributions
as well. So this change moves them out of `debian/` to
`linux/keyman-config` so that they will be included in the source
tar ball.

Also remove zero-width space from one file.

Closes #8880.
