port this dos interrupt to windows api

[NOVARSEG]

Ok this is a really important dos interrupt!

It allows file pointer operations on files up to 2^32 - 2 bytes

 QB64 could in theory handle any dos interrupt

If you need file pointers and such, just use _UNSIGNED _OFFSETs or _INTEGER64.  Then you have access to 2 ^ 64 bytes.  Why limit yourself to 32-bits when you can easily work with 64?

As for the 2^32 file size, you can just use an _UNSIGNED LONG to hold values that large.
