[ion] 24673: - Implement NtRequestWaitReplyPort. This is a simple implementation that doesn't support Callback LPC Messages yet (Since we don't make use of them). SMSS can now send API messages on the Sb Port. - With these APIs we now have a skeleton NTLPC that is fully NT-compatible. Thanks to ea's (Emanuele)'s smss work which he strived to make portable, building with NTLPC = 1 will also build a compatible smss that now works. - CSRSS requires some changes since it was not written to be NTLPC

[ion] 24665: - Implement the rest of Hard Error support. - Kernel support is complete (except temporary LPC hack), and CSRSS properly receives the event and sends it off to win32csr's hard error handler (much like on NT). However, the handler doesn't call NtUserHardErrorControl nor do much of the complex sequence of events that NT does, instead, we only display a hello-world style message box. Anyone up for implementing the rest is welcome.
