[media] mceusb: fix up reporting of trailing space
We were storing a bunch of spaces at the end of each signal, rather than a single long space. The in-kernel decoders were actually okay with this, but lirc isn't. As suggested by David Härdeman, switch to storing samples using ir_raw_event_store_with_filter, which auto-merges the consecutive space samples for us. This also allows us to bypass having to store rawir samples in our device struct, further simplifying the buffer parsing state machine. Both in-kernel decoders and lirc are happy again with this change. Also included in this patch is proper parsing of 0x9f 0x01 commands, the removal of some magic number usage and some printk spew fixups.
