Subject: [PATCH] lircd: Remove use of functions killed in kernel 4.8.0

From 4.8.0 the kernel no longer supports LIRC_NOTIFY_DECODE,
LIRC_SETUP_START/LIRC_SETUP_END and several constants related
to initiating filters. Remove corresponding calls from lircd.

[baruch: move DRVCTL_NOTIFY_DECODE into lircd.cpp]
