mp_msg: remove gettext() support

Was disabled by default, was never used, internal support was
inconsistent and poor, and there has been virtually no interest in
creating translations.

And I don't even think that a terminal program should be translated.
This is something for (hypothetical) GUIs.

-#ifdef CONFIG_GETTEXT
-    /* gettext expects the global locale to be set with
-     * setlocale(LC_ALL, ""). However doing that would suck for a
-     * couple of reasons (locale stuff is badly designed and sucks in
-     * general).
-     *
-     * First, setting the locale, especially LC_CTYPE, changes the
-     * behavior of various C functions and we don't want that - we
-     * want isalpha() for example to always behave like in the C
-     * locale.
-
-     * Second, there is no way to enforce a sane character set. All
-     * strings inside MPlayer must always be in utf-8, not in the
-     * character set specified by the system locale which could be
-     * something different and completely insane. The locale system
-     * lacks any way to say "set LC_CTYPE to utf-8, ignoring the
-     * default system locale if it specifies something different". We
-     * could try to work around that flaw by leaving LC_CTYPE to the C
-     * locale and only setting LC_MESSAGES (which is the variable that
-     * must be set to tell gettext which language to translate
-     * to). However if we leave LC_MESSAGES set then things like
-     * strerror() may produce completely garbled output when they try
-     * to translate their results but then try to convert some
-     * translated non-ASCII text to the character set specified by
-     * LC_CTYPE which would still be in the C locale (this doesn't
-     * affect gettext itself because it supports specifying the
-     * character set directly with bind_textdomain_codeset()).
-     *
-     * So the only solution (at least short of trying to work around
-     * things possibly producing non-utf-8 output) is to leave all the
-     * locale variables unset. Note that this means it's not possible
-     * to get translated output from any libraries we call if they
-     * only rely on the broken locale system to specify the language
-     * to use; this is the case with libc for example.
-     *
-     * The locale changing below is rather ugly, but hard to avoid.
-     * gettext doesn't support specifying the translation target
-     * directly, only through locale.
-     * The main actual problem this could cause is interference with
-     * other threads; that could be avoided with thread-specific
-     * locale changes, but such functionality is less standard and I
-     * think it's not worth adding pre-emptively unless someone sees
-     * an actual problem case.
