ANSI compatible strtol and strtoul, and ANSI styled other functions.

because they are defined in missing.h.
* missing.h, missing/strchr.c, missing/strstr.c: ANSI styled.

rb_exit(). [ruby-dev:26347]
* eval.c (rb_thread_signal_exit): a new function to exit on main
thread.
* eval.c (rb_thread_switch): exit status should be retrieved from
ruby_errinfo.
* eval.c (rb_f_exit): ensure exit(0) should call
exit(EXIT_SUCCESS).
* missing/mkdir.c: remove. [ruby-core:05177]
* hash.c (env_aset): do not treat nil as key-removing value.
[ruby-list:40865]
* parse.y (method_call): allow aref expression ([]) to take a
block.
* parse.y (block_dup_check): a function to check duplication of
a block argument and an actual block.
* lib/delegate.rb (SimpleDelegator::__setobj__): need check for
recursive delegation. [ruby-core:04940]
* lib/cgi.rb: add underscore aliases CGI::escape_html,
CGI::unescape_html, CGI::escape_element, CGI::unescape_element.
[ruby-core:05058]
* misc/ruby-mode.el (ruby-expr-beg): fix looking point drift.

* defines.h, rubysig.h, signal.c: removed macro handling which
should be done in configure.
* configure.in (intrinsics.h): check if present.
* ruby.h: include intrinsics.h if available.
* bignum.c, marshal.c: include ieeefp.h if available.
* missing.h (isinf): define as a macro if finite() and isnan()
are available. [ruby-core:02032]

* eval.c (ruby_finalize): no longer need to turn off $DEBUG in the
finalizer. (ruby-bugs-ja PR#473)

asin, acosh, atanh, log, log10 and sqrt.
* eval.c (rb_add_method): initialize should always be private.
* parse.y (expr): add rescue modifier rule.
* parse.y (command_call): return, break and next with argument is
now part of this rule.
* parse.y (yylex): "a" in "a /5" should be considered as a local
variable. [experimental]

* eval.c (set_method_visibility): should have clear cache forq
updated visibility.
* numeric.c (flo_to_s): default format precision to be "%.16g".
* util.c (ruby_strtod): use own strtod(3) implementation to avoid
locale hell. Due to this change "0xff".to_f no longer returns 255.0
* eval.c (avalue_to_yvalue): new function to distinguish yvalue
(no-arg == Qundef) from svalue (no-arg == Qnil).
* eval.c (rb_yield_0): use avalue_to_yvalue().
* eval.c (assign): warn if val == Qundef where it means rhs is
void (e.g. yield without value or call without argument).
* parse.y (value_expr): need not to warn for WHILE and UNTIL,
since they can have return value (via valued break).
