  Document various strtod bugs, with some fixes.
  
  * doc/posix-functions/strtod.texi (strtod): Document bugs with
  "-0x", "inf", "nan", and hex constants.
  * doc/posix-functions/atof.texi (atof): Likewise.
  * modules/stdlib (Makefile.am): Support strtod.
  * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Likewise.
  * m4/strtod.m4 (gl_FUNC_STRTOD): Fit in stdlib framework, and
  detect additional strtod bugs.
  * lib/stdlib.in.h (rpl_strtod): Add declarations.
  * lib/strtod.c (strtod): Return -0.0 on negative underflow.  Use
  bool where appropriate.  Parse 'inf' and 'nan'.
  * tests/test-strtod.c: New file.
  * modules/strtod (Depends-on): Add stdbool, stdlib.
  (configure.ac): Turn on module indicator.
  * modules/strtod-tests: New module.
