Please take a look at tools/v8windbg/README.md for an overview of what
v8windbg can do and how it's structured. This platform-specific
debugging plugin makes use of the data provided by the V8 postmortem
debugging API in tools/debug_helper.

Note: This code began as https://github.com/billti/v8dbg and then moved
into the Edge repository, where I added features gradually and got code
reviews for individual changes. Now, taken in its entirety, it's an
obnoxiously large CL. I'm open to breaking it up into a few chunks if
that would be preferable.
