Last change on this file since 73348 was 73348, checked in by vboxsync, 6 years ago

DBGF,DBGC,GIMHv: Added some basic windows bug check formatting (DBGFR3FormatBugCheck). Extended DBGFEventGenericWithArgs and DBGFEVENT to hold up to 6 64-bit arguments, so that we can pass all the bug check arguments to the debugger.
