#20 Make serial receiver more reliable

[Ian]

Because the timing in done on the CPU, if CPU usage is high, decoding will fail completely.

void CIRDriver::ThreadProc(void)
should be given real time priority

The handle must have the THREAD_SET_INFORMATION access right.

The transmit part of the source messes with the priorities.

The decoding thread can also fail under high CPU load. In my audiocapture plugin I buffer the data until I think the end of the signal has been reached, and then I kick off decoding. This might help the serial plugin and decoding, or may not :)

Fixed in r244.

If the decoding is still unreliable, it might be because winlirc did not have enough privileges to boost its priority class to Realtime (non-admins only get High). To fix this, either winlirc must be started as admin or task manager (or orher tool) be used to set the process priority to Realtime.
