[version/info.c] Start of conversion fixes

[Paul Vriens]

Hi,

this patch makes sure that enough space is reserved for the structure. The
patch is based on testing on W2K/XP/W2K3, and this is where the
calculations come from. The extra space is needed for conversion needs.
VerQueryValueA put's ANSI strings (converted from UNICODE if 32bits) into
this area, VerQueryValueW put's UNICODE strings (converted from ANSI if
16bits) into this area. The '#if 0' are there, cause I still haven't
figured how to get rid of the warnings. If warnings would have been
acceptable the patch would make sure that the conversion are indeed placed
in the extra space (instead of in the structure as it is right now).

Changelog
  Reserve extra space for conversions.

Cheers,

Paul.
