Fix #1024 by changing decode channel assigment to PDs

When assigning the decoder stack channels to the libsrd
instance's channels, channels that had no signal assigned
to them were still assigned anyway. This patch fixes this bug.

After doing this, another subtle bug became apparent:
The mapping between channels and bits in the data stream sent
to the PD was done via DecodeChannel->id. This is however
insufficient as the channels of the decoder stack have
IDs that may or may not match the ID needed for the data
stream. Example:

A PD has 4 channels: A, B, C and D. In PV, those channels
have the IDs 0, 1, 2 and 3. If the user only assigns A and D,
Decoder::create_decoder_inst() will use the IDs 0 and 3 as
the bit positions of those signals in the data stream sent
to libsrd. This is obviously wrong.

Hence, we now use a separate bit_id for this purpose.

SignalBase: Adjust Schmitt-trigger thresholds

Currently, the thresholds are determined by the minimum
and maximum values of a signal. From those, we derive the
high and low thresholds by using a 10% margin to min/max.

However, this approach doesn't work very well when the
measurement includes reset conditions or similar, causing
spikes that raise the min/max significantly.


This patch changes the thresholds margins to 35%. However,
they are expressed differently: (max-min)/2 is used as the
center line, from which 15% of the amplitude (max-min) is
used as the margin. This way seems a little more intuitive
for me since the percentage given (15) is directly proportional
to the hysteresis.

Decode: Improve signaling

Three issues that were fixed by this:
1) The SignalBase did notify PDs when its conversion changed
and new sample data was generated but this was dismissed as
the samples_cleared() signal was never fired nor used by the
PD stack.

2) The decode_finished() signal was added so that the decode
trace can immediately paint the trace once the PD is done.
Before, a repaint was only triggered when annotations came in,
resulting in a noticeable "unresolved period" visible if the
last stretch of signal didn't contain any annotations as the
trace wasn't repainted quickly enough.

3) The decode trace indirectly looks at the signal's
samples_decoded_ member when drawing the "unresolved period"
bar. Hence we should update this member before triggering the
repaint via new_annotations().

DecodeSignal: Adjust the DecodeChunkLength

The initial 4096 was too low, though it did make the UI
quite responsive. In 9cc264 it was increased to 10*1024*1024
to speed up decoding but that makes the UI stall very badly
under certain circumstances (e.g. when changing the baud rate
for UART by entering digits).
The reason is that every time a decoder property is changed,
the decode is restarted. Restarting the decode means that
the currently running processes need to shut down, so
they're told to do so and the GUI thread waits for them
to finish.
However, the srd_session_send() call is blocking, meaning
that libsrd will happily block the PV GUI thread until it's
done processing the current chunk of data.

For this reason, DecodeChunkLength can't be too high and
256*1024 looks like a reasonable compromise for now.

responsive in return.

Instead, use a one-shot timer with a fixed delay to redraw
the trace after data has been processed. This way, there is
an upper bound to how often we redraw the trace while at the
same time providing a fixed interval at which we update,
regardless of how many annotations came in, making the
trace fill up continuously.

With that in place, we can also remove annotation_count_
