Move initialization code of protocol decoders from the constructor to a
new reset() helper method. The libsigrokdecode backend could run this
method several times to clear the decoder's internal state, before new
data from another acquisition gets fed to decode() calls.
|

This allows frontends to set the assumed initial pins (i.e., the assumed
state of the pins before the first sample of a capture) to user-specified
values.
The assumed initial pins can be either low, or high, or "use same value
as the first sample of the capture".
The special self.initial_pins decoder attribute is now removed.

Use the same scale.

Instead of only measuring the timing from any edge to any edge, provide
a mode to measure the times from falling->falling and rising->rising
edges. This works better to monitor timing of an IRQ pin for instance,
that drives one direction under hardware, and is only cleared by
software reading a value.
Include time delta measurements as an optional annotation to help track
jitter in measurements.

The extra row of the average isn't always useful. Allow it to be
disabled by setting the average window to zero.

Remove the FSF postal address as it might change (it did in the past).
Reference the gnu.org website instead which is more stable.

The previous **kwargs some PDs had is not actually ever used, so drop it.
