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.

As was pointed out to me on irc by Maxim, this is actually due to using ir_raw_event_store_with_filter without having set up a timeout value. The hardware has a timeout value we're now reading and storing, which properly enables the transition to idle in the raw event storage process, and makes IR decode behave correctly w/o keybounce. Also remove no-longer-used ir_raw_event struct from mceusb_dev struct and add as-yet-unused enable flags for carrier reports and learning mode, which I'll hopefully start wiring up sooner than later. While looking into that, found evidence that 0x9f 0x15 responses are only non-zero when the short-range learning sensor is used, so correct the debug spew message, and then suppress it when using the standard long-range sensor.

Rather it creates it as virtual device. As a result, udev cannot use the USB device information to create persistent device names for event and lirc devices associated with the rc device. Not having persistent device names makes it more difficult to make use of the devices in userspace as their names can change.

The leak if we try to read an invalid length is the main concern because it could be triggered over and over. If the copy_to_user() failed, then the original code returned the number of bytes remaining. read() is supposed to be the opposite way, where we return the number of bytes copied. I changed it to just return -EFAULT on errors. Also I changed the debug output from "-EFAULT" to just "" because it isn't -EFAULT necessarily. And since we go though that path if the length is invalid now, there was another debug print that I removed.

Looking back over the old lirc driver, tx_mask_inverted was set to 0 if the device was in tx_mask_list. Now we have a tx_mask_inverted flag set to 1 for all the devices that were in the list, and set tx_mask_inverted to that flag value, which is actually the opposite of what we used to set, causing set_tx_mask to use the wrong mask setting option. Since there seem to be more devices with inverted masks than not (using the original device as the baseline for inverted vs. normal), lets just call the ones currently marked as inverted normal instead, and flip the if/else actions that key off of the inverted flag. Note: the problem only cropped up if a call to set_tx_mask was made, if no mask was set, the device would work just fine, which is why this managed to slip though w/o getting noticed until now. Tested successfully by myself and Dennis Gilmore.
