Log:
Patch by Anton Yarotsky:
[NTOSKRNL]: Implement basic Headless support in the kernel. Implement missing InbvPort
routines based on WinLdrPort (using cportlib). Add header for Hdl. Terminal initializes
now on COM2. Added misisng code to InbvDisplayString to also display on Headless Terminal
(requires unimplemented HeadlessDispatch). Next steps are to implement the kernel log
buffer, and HeadlessCmdPutString to see boot strings.
