  m4: rework silent-rules macros to avoid double expansion
  
  Fixes automake bug https://bugs.gnu.org/32868.
  
  The AM_SILENT_RULES macro defines all the silent-rules related setup.
  It's also called by users to change the default verbosity level.  This
  leads to a quirk where automake calls it, expands the full context,
  and then users call it, and it's fully expanded again.
  
  Instead, let's rename AM_SILENT_RULES to _AM_SILENT_RULES and move the
  initialization logic to late in the configure stage.  This allows the
  user-centric AM_SILENT_RULES call to expand into a single line to set
  the default verbosity.
  
  * m4/init.m4: Switch to _AM_SILENT_RULES.
  * m4/silent.m4: Rename AM_SILENT_RULES to _AM_SILENT_RULES.  Delay
  evaluation of AM_SILENT_RULES to the end.  Define new AM_SILENT_RULES to
  set default rules verbosity.
  * t/silent-defaults.sh: New tests.
  * t/list-of-tests.mk: Add t/silent-defaults.sh.
