meson: gtkdoc support

Bunch of neat improvements:

- xml generates correctly depend upon the test binaries
- no need to re-run autogen.sh when new chapters/functions get added,
  all handed by meson

Still one issue:

- the gtkdoc target doesn't depend upon the custom_target yet, hacked
  around using build_by_default: true

  This is an issue known to upstream already:

  https://github.com/mesonbuild/meson/issues/2148

v2: Bump meson version to 0.42, since that's the first release which
adds the build dir when running the gtkdoc tools, and hence allows
including generated files.

v2:
- Undo the bump, it's only needed for generated source files. Other
  generated files as input should work with 0.40 already.

- Generate version.xml from version.xml.in, which allows us to keep
  the &version; entity.

v3: Add github issue link.

v4:
- Resurrect lost KEYWORDS (Petri)
- Fix issue when running with a clean build, files() doesn't work on generate
  files (Petri).
