Log Message:
Use the comm page to inject events, rather than ioctls, and commit them in
vcpu_run. This saves a few syscalls and copyins.

For example on Windows 10, moving the mouse from the left to right sides of
the screen generates ~500 events, which now don't result in syscalls.

The error handling is done in vcpu_run and it is less precise, but this
doesn't matter a lot, and will be solved with future NVMM error codes.
