Merge branch 'master' into ng/master

* master:
  automake: stop supporting "%KEY?iftrue:iffalse%" transforms
  am: stop using "%KEY:iffalse?iftrue%" transforms
  tests: minor reorganization of few tests
  fixup: adjust t/list-of-tests.mk for renamed/added tests
  subdirs: enhance coverage, tweak and rename few tests
  sync: update files from upstream with "make fetch"
  py-compile: consistently quote 'like this', not `like this'.
  docs: recursive make considered harmful
  docs: clean rules are not run in reverse order of build rules anymore
  silent: new $(AM_V_P) variable, tell if we're running in silent mode
  refactor: silent rules handling (a little)
  refactor: &define_verbose_var: accept a third optional argument

+ Extra non-trivial edits:

* t/dir-named-obj-is-bad.sh, t/sourcefile-in-subdir.sh: Delete, it's how
the old (and in Automake-NG obsolete and removed) tests 't/subdir3.sh'
and 't/subdir7.sh' have been respectively renamed in mainline Automake.
* t/silent6.sh: Don't disable the 'portability-recursive' warnings, they
are not anymore used nor supported by Automake-NG.
* automake.in: Adjust calls to subroutines '&Automake::Variable::define'
and '&define_variable' to the different Automake-NG APIs and signature.
