std/stdarg.di and std/c/stdarg.di need alias void* va_list for tangobos compatibility

Description (Last modified by baxissimo)

Tangobos uses 'va_list' in a couple of places. In Tango's version stdarg.di this only gets defined for version(GNU).

The Tangobos block used in both cases contains: 

version(GNU) {
 ...
} else {
    alias void* va_list;
}

The issue arises from the fact that Tangobos and Tango both have copies of std.stdarg and std.c.stdarg. When installing using dsss one's version gets copied over the other's. If you re-install tango subsequent to installing Tangobos then Tango's versions will overwrite Tangobos's, and things like std.stdio will stop working because they use va_list.

There are other differences between the Tangobos and Tango versions of stdarg. They need to be resolved. Ideally, Tangobos shouldn't need to have its own versions of these files at all since they are included with Tango. But Tango's versions at least need to get the va_list alias for that to be possible.

You have gotten the symptoms right, but the reasons behind are different. Tango only has std.stdarg because it is hardcoded into GDC - it is not needed, nor used, for DMD, and shouldn't be for GDC. Problems in std.* can be rectified by importing tango.core.Vararg instead of std.stdarg. That should in a problem only for those applications using std.stdarg in the event that Tango is re-installed after Tangobos is installed.

Got some unexpected results when I tested a few things - will get back to this soon.

Ok, this is fixed. Will make sure Tangobos follows suit.

This is further tracked in #1001, but bottom line is - this is not resolved.
