6 years agooutput/wav: change default for scale factor from 0.0 to 1.0

output/wav: change default for scale factor from 0.0 to 1.0

The WAV output module supports an optional 'scale' factor, in its
absence the samples will pass unmodified. The builtin help text is
unexpected, and reads:

  $ sigrok-cli -O wav --show

    scale: Scale values by factor (default 0.0)

output/vcd: assume packed input data image, unbreak 2nd+ channel

channels, and "saw no changes" after emission of the initial value for
channels on positions that followed a disabled channel.

Assume that the received data from the session bus communicates the bits
of enabled channels in a packed representation. Skip the mapping of
output bit indices to sigrok channel numbers.

This fixes the remaining part of bug #519.

  $ sigrok-cli -d demo -C D1,D3,D6 -c samplerate=2M --samples 2500 -O vcd -o trace.vcd

provide a dense bit field, all of the mapping logic can get removed
here. This commit just quickly disables the logic.
