This patch moves int25 and int26 to winedos and creates functions
DOSVM_RawRead and DOSVM_RawWrite. The plan is to make int21 use these
functions instead of DRIVE_RawRead and DRIVE_RawWrite. These two
DRIVE_ functions are used only by int25, int26 and int21 handlers.
Changelog:
Moved handlers for int25 and int26 to winedos.
Files msdos/int25.c and msdos/int26.c can be removed after this patch.
