Switch VEH to VCH and allow disabling of SEH completely.
Exception handling on Windows is unfortunately a bit complicated.
But essentially the VEH Handlers we currently have are running too
early.
This was a problem as it ran so early it also swallowed C++ exceptions
and other software exceptions which the system could have very well
recovered from.
So instead we use a sequence of chains to for the exception handlers to
run as late as possible. You really can't get any later than this.
Please read the comment in the patch for more details.
I'm also providing a switch to allow people to turn off the exception
handling entirely. In case it does present a problem with their code.
