[patch] cc-mode 5.30.3; function for `c-init-language-vars'

[Wedler, C. <chr...@sa...>]

Hi Martin,

I really like the changes you made since v5.28 of cc-mode, they are
especially useful for me as the author of a derived mode (antlr-mode,
see <http://antlr-mode.sourceforge.net/>, we had a discussion about such
changes a year ago).

Of the two changes between v5.29 and v5.30, I find one very useful, and
would appreciate if you could make some modification of the other one
(e.g., by applying the appended patch):

 1. The introduction of `c-basic-common-init' is very useful as I don't
    have to care about internal changes of cc-mode.

 2. The introduction of `c-init-language-vars' (already in v5.29) is
    also very useful, it eliminates a dependency between the source code
    of my antlr-mode and cc-mode.

    Unfortunately, having it as a macro (as opposed to v5.29) now
    introduces a dependency between the byte code of my antlr-mode and
    cc-mode.  (This is especially bad for XEmacs, where there are
    different pre-compiled packages: there is a cc-mode package,
    antlr-mode is part of the prog-modes package.)

    Therefore, I would really like if you could offer a *function* to
    initialize the variables of the "built-in" languages of cc-mode.
    (This function is called `c-init-language-vars-for' in my patch, any
    other name, including the name of the macro which is then to be
    renamed, is fine with me.  Splitting this function into one for each
    mode would also be fine.)

The patch (for cc-mode.el only) is appended, it is vs v5.30.3.

Thanks and best regards,
