This patch replaces if chain that selects the message with
2 dimensional array of format strings and arguments.

This patch is unrelated with previous one, but related to GSoC.
So I don't know if I should create new thread for this patch.
Compare with original construction
Pros:
1) Remove if chain.
2) Single table contains all messages with arguments in one contruction.
3) Less code duplication.
Cons:
1) Harder to associate the case with message.
2) Harder for compiler to warn the programmer about not
enough arguments for format string.
3) Harder to add non-string argument to messages.
If !!(x) is out of the coding guide, then message_id construction
can be rewritten in several other ways.
The guideline tells that !!(x) is not welcome and should not be
unless needed. But looks like this is normal place for it.
P.S.
Thanks to comments I got, so
I've read more GNU gettext manual to get info
about translation workflow. When I posted a first patch
I've passed the same message format strings to gettext /*_()*/
as in original, to save the context of the message. And they
will be translated if every possible string combination
will be marked separately for translation. Because of
xgettext can extract string from source automatically,
it ruins the idea to generate message from parts. Even if the
exaclty same message format string is passed to gettext.
