Fix space flag when Inf/NaN and width==3

	* sprintf.c (rb_str_format): while `"% 2f"` and `"% 4f"` result in
	  `" Inf"` and `" Inf"` respectively, `"% 3f"` results in
	  `"Inf"` (no space).
	Refactor "%f" % Inf/NaN

	* sprintf.c (rb_str_format): as for non-finite float, calculate
	  the exact needed size with the space flag.

Use PRIuSIZE instead of PRIdSIZE. This fixes the exception message shown
on too large xmalloc2. This commit also fixes other incorrect use of
PRIdSIZE in other functions; though most of them are debug print.

* gc.c (heap_extend_pages, get_envparam_size, ruby_malloc_size_overflow,
  gc_profile_dump_on): Use PRIuSIZE instead of PRIdSIZE as the passed
  value is size_t, not ssize_t.

* iseq.c (get_line_info, rb_iseq_disasm_insn): Ditto.

* sprintf.c (rb_str_format): Ditto.

* thread_win32.c (native_thread_create): Ditto.

* vm.c (get_param): Ditto.

* ext/objspace/objspace_dump.c (dump_append_string_content,
  dump_object): Ditto.

* ext/socket/raddrinfo.c (host_str, port_str): Ditto.

* include/ruby/ruby.h (RB_INTEGER_TYPE_P): new macro and
  underlying inline function to check if the object is an
  Integer (Fixnum or Bignum).

* [Feature #12005] Unify Fixnum and Bignum into Integer

* include/ruby/ruby.h (rb_class_of): Return rb_cInteger for fixnums.

* insns.def (INTEGER_REDEFINED_OP_FLAG): Unified from
  FIXNUM_REDEFINED_OP_FLAG and BIGNUM_REDEFINED_OP_FLAG.

* vm_core.h: Ditto.

* vm_insnhelper.c (opt_eq_func): Use INTEGER_REDEFINED_OP_FLAG instead
  of FIXNUM_REDEFINED_OP_FLAG.

* vm.c (vm_redefinition_check_flag): Use rb_cInteger instead of
  rb_cFixnum and rb_cBignum.
  (C): Use Integer instead of Fixnum and Bignum.

* numeric.c (fix_succ): Removed.
  (Init_Numeric): Define Fixnum as Integer.

* bignum.c (bignew): Use rb_cInteger instead of Rb_cBignum.
  (rb_int_coerce): replaced from rb_big_coerce and return fixnums
  as-is.
  (Init_Bignum): Define Bignum as Integer.
  Don't define ===.

* error.c (builtin_class_name): Return "Integer" for fixnums.

* sprintf.c (ruby__sfvextra): Use rb_cInteger instead of rb_cFixnum.

* ext/-test-/testutil: New directory to test.
  Currently it provides utilities for fixnum and bignum.

* ext/json/generator/generator.c: Define mInteger_to_json.

* lib/mathn.rb (Fixnum#/): Redefinition removed.
