Fix bootstrapping problems.

Use the system locale to specify Emacs locale defaults.

* international/mule-cmds.el (global-map):
Do not use backquote, because that makes a bootstrapping
problem if you need to recompile all Lisp files using interpreted code.
* international/mule.el (charset-id, charset-bytes,
charset-dimension, charset-chars, charset-width,
charset-direction, charset-iso-final-char,
charset-iso-graphic-plane, charset-reverse-charset,
charset-short-name, charset-long-name, charset-description,
charset-plist): Likewise.
* subr.el (save-match-data): Likewise.

* international/mule-cmds.el
(set-display-table-and-terminal-coding-system): New function,
containing code migrated out of set-language-environment.
(set-language-environment, set-locale-environment): Use it.
(locale-translation-file-name): Moved here from startup.el.
(locale-language-names, locale-preferred-coding-systems):
New vars.
(locale-name-match, set-locale-environment): New functions.

* language/japan-util.el (setup-japanese-environment-internal):
Prefer japanese-iso-8bit if the system-type is usg-unix-v.

* startup.el (iso-8859-n-locale-regexp): Remove.
(locale-translation-file-name): Move to mule-cmds.el.
(command-line): Move locale-stuff into set-locale-environment.
