* demangle.h: Remove uses of PARAMS.
* libiberty.h (ANSI_PROTOTYPES): Remove guard since
ANSI_PROTOTYPES is always assumed.
Remove uses of PARAMS throughout.

prototype.
* argv.c: Remove conditional #includes on ANSI_PROTOTYPES.
(dupargv, freeargv, buildargv, main): Use ISO C prototype.
* atexit.c (atexit): Likewise
* asprintf.c: Remove conditional include on ANSI_PROTOTYPES.
(asprintf): Use ISO C prototype.
* basename.c (basename): Likewise
* bcmp.c (bcmp): Likewise.
* bcopy.c (bcopy): Likewise.
* bzero.c (bzero): Likewise.
* bsearch.c (bsearch): Likewise. Improve const-correctness.
* choose-temp.c (choose_temp_base): Likewise.
* calloc.c: Remove conditional #include on ANSI_PROTOTYPES.
(calloc): Use ISO C prototype.
* clock.c (clock): Likewise.
* concat.c: Remove conditional #include on ANSI_PROTOTYPES.
(vconcat_length, vconcat_copy, concat_length, concat_copy,
