[pvrusb2] HVR-1950 IR Support

[Roger]

With the lirc driver compiled statically into the kernel, seems MPlayer is 
pulling IR key/button events straight from the /dev/input/event interface with 
no need for lirc userspace daemon, lirc userspace package or configuring any 
lirc relevant configuration files.

And somewhere, the remote's button events are configured statically for 
triggering MPlayer events.  ~/.lircrc and /etc/lirc/* files appear irrelevant.

I saw one wiki/howto page stating something about blacklisting an lirc core 
module to prevent double key/button detection.  I'm guessing this is required 
if you want to use the lirc userspace package (with devinput driver) and your 
lircrc files.

For now, I'm going to focus on using the kernel lirc module and making mplayer 
recognize the other currently unrecognized remote buttons.

But I'm seeing three methods or interfaces to use the HVR-1950 IR 
receiver/remote device.

1) ir-kbd-i2c (i2c device)

2) devinput (Only requires in kernel lirc module) to work with MPlayer

3) lirc_zilog (Linux Kernel Staging Drivers drivers/staging/linux/lirc) will 
also interface with the pvrusb2 driver.

So many methods, yet devinput seems to be the more future method then the 
others -- yet no method to configure buttons without using lirc userspace?

Confused.  Hate to say it, but this looks like a mess!
