Lars-Peter Clausen f18e0db3b8 demo: Handle the case when zero analog or logic channels were requested
The demo device has support for specifying the number of analog and logic
channels it should have. Currently this does not work correctly if one of
them is set to zero. Being able to set the number of channels to zero for
one of the channel types is quite useful for corner case testing though.

Make the following modifications to handle it correctly:

1) If the channel count is zero no channel group for that channel type
should be created since a channel group needs at least one channel.

2) Drop the check if logic_unitsize is less or equal to zero in
prepare_data() since this condition will always be true if the number of
logic channels is zero and it is not possible to create a demo device with
only analog channels.

README

-------------------------------------------------------------------------------
README
-------------------------------------------------------------------------------

The sigrok project aims at creating a portable, cross-platform,
Free/Libre/Open-Source signal analysis software suite that supports various
device types (such as logic analyzers, oscilloscopes, multimeters, and more).

libsigrok is a shared library written in C which provides the basic API
for talking to hardware and reading/writing the acquired data into various
input/output file formats.


Status
------

libsigrok is in a usable state and has had official tarball releases.

While the API can change from release to release, this will always be
properly documented and reflected in the package version number and
in the shared library / libtool / .so-file version numbers.

However, there are _NO_ guarantees at all for stable APIs in git snapshots!
Distro packagers should only use released tarballs (no git snapshots).


Requirements
------------

Requirements for the C library:

 - git (only needed when building from git)
 - gcc (>= 4.0) or clang
