[reactos] 02/02: [NTOS:KE/MM] Some bug-fixes in the bugcheck code.

Indeed, this latter function patches in place the bugcheck resource message to trim any trailing newlines before displaying the message on screen. See also https://github.com/osresearch/uxen/blob/83bad53/dm/introspection-win7.c#L286 that mentions it too. This fixes bugcheck text display (e.g. the MANUALLY_INITIATED_CRASH one) when using (at least) MSVC-built ReactOS, avoiding a Page-Fault exception during the bugcheck. - Cover KeGetBugMessageText() in SEH since we are accessing kernel resources that could also be corrupted in bugcheck scenarii, and we don't want to further bugcheck. - Fix newline trimming loop. - KiDoBugCheckCallbacks(): * Wrap the bugcheck CallbackRoutine call in SEH. * Add a FIXME concerning the need of further memory validation of CurrentRecord. - Add a FIXME concerning the need to run the bugcheck-reason callbacks with the KbCallbackReserved1 reason, in KeBugCheckWithTf().
