  Support several gnulib-tool invocations under the same configure.ac.
  
  Reported by Reuben Thomas <rrt@sc3d.org> in
  <https://lists.gnu.org/archive/html/bug-gnulib/2021-04/msg00104.html>.
  
  This is done by defining the Gnulib module indicator variables per
  gnulib-tool invocation. So that a generated .h file is no longer
  influenced by the set of modules used in other gnulib-tool invocations.
  
  * gnulib-tool (func_compute_include_guard_prefix): Set
  module_indicator_prefix.
  (func_emit_lib_Makefile_am, func_emit_tests_Makefile_am): Use it to
  modify $(GNULIB_*) variable references in the Automake snippets.
  (func_emit_initmacro_start): Push macro definitions for GL_MACRO_PREFIX
  and GL_MODULE_INDICATOR_PREFIX.
  (func_emit_initmacro_end): Pop these macro definitions.
  * pygnulib/GLConfig.py (GLConfig.getIncludeGuardPrefix): New method.
  * pygnulib/GLEmiter.py (GLEmiter.initmacro_start): Push macro
  definitions for GL_MACRO_PREFIX and GL_MODULE_INDICATOR_PREFIX.
  (GLEmiter.initmacro_end): Pop these macro definitions.
  (GLEmiter.lib_Makefile_am, GLEmiter.tests_Makefile_am): Use the module
  indicator prefix to modify $(GNULIB_*) variable references in the
  Automake snippets.
  * m4/gnulib-common.m4 (gl_MODULE_INDICATOR_INIT_VARIABLE,
  gl_MODULE_INDICATOR_SET_VARIABLE): Use the value of
  GL_MODULE_INDICATOR_PREFIX.
  * m4/arpa_inet_h.m4: Use new idiom for header files that contain
  references to Gnulib module indicator variables:
  - Define the main macro through AC_DEFUN_ONCE.
  - Define a macro gl_*_H_REQUIRE_DEFAULTS that initializes the Gnulib
    module indicator variables (each prefixed with
    GL_MODULE_INDICATOR_PREFIX).
  - Invoke this macro in the gl_*_MODULE_INDICATOR macro.
