[lldb-dev] Refactoring in LLDB Windows Plugin

I have no objection to moving in that direction (enabling remote
debugging).  Zach just pointed out that we'd first have to port lldb-server
to Windows.  Offhand, I don't know how much of an effort that would be.

In the near-term, I'm focused on postmortem debugging, so this wouldn't be
a priority for me for a while.

The "unfactoring" I mentioned in this email is essentially done, though I'm
planning to move some files to eliminate an unnecessary subdirectory from
the source paths.
