It was only used in one place, which did not use va_list.
Looking at the original issue, my guess was whatever this was meant to
work around was an issue in DevilutionX code at the time.
`DVL_ERROR_HANDLE_EOF` was defined incorrectly on Windows.
These error codes are used and returned by Storm. Moves them
from `miniwin.h` to `storm.h`.
Also adds `STORM_ERROR_FILE_NOT_FOUND`, to be used in a follow-up PR.
SErrGet/SetLastError were not propagating errors from 3rdParty/StormLib
because StormLib uses native Windows functions on Windows and defines
its own on Linux.
Also removes storm_full.h
