  sys_time: use link-warning
  
  Modernize replacement header, to allow another GNULIB_POSIXCHECK
  opportunity.
  
  * m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H_BODY): Split defaults...
  (gl_HEADER_SYS_TIME_H_DEFAULTS): ...into new macro.
  (gl_SYS_TIME_MODULE_INDICATOR): New macro.
  * modules/sys_time (Depends-on): Add warn-on-use.
  (Makefile.am): Always build replacement.
  (configure.ac): Update substitutions.
  * m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY)
  (gl_FUNC_GETTIMEOFDAY_CLOBBER): Include defaults, and no longer
  bother with SYS_TIME_H.
  * modules/gettimeofday (configure.ac): Declare indicator.
  * lib/sys_time.in.h (gettimeofday): Warn if gnulib module is not
  in use.
