C99 bfd configury

Certain library headers and functions are required by C99.  This
removes configure tests for them.  The patch also removes AC_ISC_POSIX
and AC_HEADER_DIRENT, which the autoconf manual states are obsolescent.
sys/time.h is no longer tangled up with time.h so it can be handled by
the gprof configure.

	* configure.ac: Don't check for long long or long double type.
	Don't check for alloca.h, limits.h, stddef.h, stdlib.h, string.h,
	strings.h, time.h, wchar.h, wctype.h or sys/time.h.  Don't check
	for strtoull, free, malloc, realloc, getenv, strstr, snprintf,
	vsnprintf, strlen or setitimer.  Sort AC_CHECK_DECLS.
	(AC_ISC_POSIX): Don't invoke.
	(AC_HEADER_TIME, AC_HEADER_DIRENT, ACX_HEADER_STRING): Likewise.
	* sysdep.h: Remove many HAVE_*_H checks and fallback declarations.
	Do test HAVE_SYS_TYPES_H.  Don't include sys/time.h.  Reorder
	header order as per automake AC_INCLUDES_DEFAULT.
	* bfd-in.h: Include inttypes.h unconditionally.
	* bfd.c (_bfd_doprnt, _bfd_doprnt_scan): Assume long long and
	long double are available.
	(bfd_scan_vma): Assume long long and strtoull are available.
	* elflink.c: Include limits.h unconditionally.
	* elfnn-riscv.c: Likewise.
	* wasm-module.c: Likewise.
	* hpux-core.c: Include dirent.h unconditionally.
	* trad-core.c: Likewise.
	* hosts/x86-64linux.h: Include stdlib.h unconditionally.
	* peXXigen.c: Remove HAVE_WCHAR_H and HAVE_WCTYPE_H checks.
	* elf32-m68hc1x.c: Don't include alloca-conf.h.
	* elf64-hppa.c: Likewise.
	* som.c: Likewise.
	* wasm-module.c: Likewise.
	* xsym.c: Likewise.
	* bfd-in2.h: Regenerate.
	* config.in: Regenerate.
	* configure: Regenerate.
