* Fix some subtle timing issues with gpio.pulse
* Add the pulse:update method
* Allow getstate to work on stopped pulsers
* Make gpio.mode(, gpio.OUTPUT) actually set the output mode
* Added some more documentation
* Add support of counting of interrupts
* Update the timestamp when interrupt happens during dispatch. Also
clear out interrupts when setting up a new callback
* Check the return code of the read function when doing crypto.fhash so that we don't pass negative lengths to the hashing functions
* Fix various assert failures in the LVM arising from rotables. No functional change
* Add the gpio interrupt time to the callback (and pass it from the interrupt handler)
* Get the PC right in the perf module
* Make the headers static in the websocket module
* Fix the documentation
