b5b8b59870 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE). 
Update the long comment explaining it.

m4_require no longer writes an ``is required by'' line to the
execution stack.  It contains only one bit of non-redundant
information: that the macro was required, not called.  And even
this bit is useless in most situations: have you ever met a macro
which both calls and requires the same macro?

* lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
(_m4_defun_pro_outer): ... only via this macro, for the outermost
  macro.
(_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
(m4_expansion_stack_pop): Remove the misplaced comment.
(m4_require): Don't put the ``is required by'' line to the
  execution stack; slightly improve the out-of-a-defun error message.
(_m4_divert_grow): New macro, counter for the temporary diversions.
(_m4_require_call): Use it.
* tests/m4sugar.at (m4_require): Expect output without the
  ``is required by'' messages.
