qemu-timer.c: Use upstream version.

This completely modifies the implementation of timers to match upstream,
the only difference is that the oddly-placed qemu_gpoll_ns() function is
disabled (it's not used yet).

Most of the changes here (but not all), were applied through the following
sed script:

+ Disable icount-based clock warping/adjustments. It will be re-enabled in the future
  after cpu emulation has been completely refactored.
