pwm_cycle_time: New module for output pins with dynamic cycle times

Browse source 
Remove support for changing the cycle time of pwm pins from the
output_pin module.  Use a new pwm_cycle_time module that supports
setting dynamic cycle times.  This simplifies the output_pin code and
low-level pin update code.

#### SET_PIN
`SET_PIN PIN=config_name VALUE=<value> [CYCLE_TIME=<cycle_time>]`: Set
the pin to the given output `VALUE`. VALUE should be 0 or 1 for
"digital" output pins. For PWM pins, set to a value between 0.0 and
1.0, or between 0.0 and `scale` if a scale is configured in the
output_pin config section.
Some pins (currently only "soft PWM" pins) support setting an explicit
cycle time using the CYCLE_TIME parameter (specified in seconds). Note
that the CYCLE_TIME parameter is not stored between SET_PIN commands
(any SET_PIN command without an explicit CYCLE_TIME parameter will use
the `cycle_time` specified in the output_pin config section).
