[hypermail] printf and i18n

Did we ever sort it out how we should deal with localized strings? IMHO, it is a good thing to be able to generate pages using different languages, but I think we should keep the diagnostics and general hypermail strings in english.

On the related subject of doing correctly output strings, we might need fully supported %N$s-style print formats to modify in which order arguments are used. The file src/mprintf.c was added by me for printf() portability reasons a long time ago (including snprintf). Now, there has been a few bugs discovered in that file since it was imported to hypermail, and there's even a separate sub-project now that works on the portable printf() issue: Trio.

I suggest that we incorporate Trio instead, and remove the src/mprintf.c.

(Note: I am co-authoring the Trio package and I wrote a fair part of the src/mprintf.c implementation too.)
