V4L/DVB (4879): budget-ci IR: integrate with ir-common 

This converts the budget-ci driver so that it uses ir-common for some of its
IR processing. In particular, the keymap for the Nova-T (sub 13c2:1011) is
switched to the Hauppauge grey/black keymap, of which the keys on the
supplied R808 remote control form a subset.
The old budget-ci keymap is moved to ir-keymaps.c and is used for other
remotes.
The debounce logic for buggy remotes (i.e. Zenith) is made conditional the
new debounce parameter and defaults to off (so that repeat keypresses aren't
ignored for all working remotes).
Some parts are based on Darren Salt's dvb-ir patchset.
