Log:
- Add 'simple' implementation of MmDbgCopyMemory to read/write virtual memory in a
somewhat safe way (still no support for physical memory). Properly implement
KdpCopyMemoryChunks as a wrapper around MmDbgCopyMemory and make most of the remaining
unsafe copies use it instead of RtlCopyMemory. This fixes most of the remaining crashes
during KD debugging as WinDbg/KD relies on the kernel support to handle bad addresses.
- Stub out the remaining missing global variables for the debugger data block -- fixes
some cases of WinDbg failures and gives it a chance to handle errors instead of failing on
a NULL read. Several of these variables are for functionality we don't yet implement,
so I tried to put them where they are "least wrong". Everything besides the
MmLoadedUserImageList variable is left unitialized -- KD should mostly be able to handle
this properly.
- Define correctly sized KDDEBUGGER_DATA64 for our kernel (needs to be done in a better
way).
