Title: lirc_rpi: Added inverted transmitter support

This adds an invert parameter to the transmitting code, which analogous to the sense parameter for the receiving code. It is specifically useful for the Pioneer SR control bus but may be useful for other unusual transmit circuits. With this patch the pi can connect directly to the SR bus through a level shifter.
