[PATCH v2 0/1] MR7906: vwin32.vxd: Add support for VxDCall() 0x0010 and 0x002a services

[Pali Rohár (＠pali)]

VxDCall vwin32 service id 0x0010 provides int21 dispatch functionality and
VxDCall vwin32 service id 0x002a provides int41 dispatch functionality.

All of these vwin32 services together with existing service id 0x0029
(for int31/dpmi functionality) have same API, first VxDCall() argument is
value for EAX register and second argument is value for ECX register.

VxDCall vwin32 service id 0x0010 is used by applications in Andrew
Schulman's book Unauthorized Windows 95. For example by CHGDIR for
getting PSP.
