[Info-vax] the document describing the system service transfer vector

[hb]

Hi Camiel,

https://vmsbug.eng.vmssoftware.com/mediawiki/index.php/File:ModularExecutive.docx 
is the document. As I said, I think it should be updated.

As explained in the document, the linker leaves 64 bytes for writing the 
actual transfer vector in the system service loader. The additional code 
to touch the stack should fit in.
