Uhm, this should be easy as the code is already there. All output from
libecasound is sent to a debug object. And like many other parts of
ecasound, also debugging system is modular - ie. you can implement
custom debug-objects. There's currently three different versions

1) ecasound/libecasound/eca-debug.cpp
- this is the simplest debug object
- outputs everything to stderr without any ncurses stuff
2) ecasound/ecasound/textdebug.cpp
- this is the ncurses based debug object which is used
  by ecasound itself
3) qtecasound/qtecasound/debug_if.cpp
- this a Qt-based widget used by qtecasound

... ok, so all we need to do is to add a command-line option to ecasound
which will disable the use of (2). Suggestions... hmm, maybe a second
parameter to -d ... so -d:255,0 would use (2) and enable all debug
messages while -d:255,1 would use (1)...?
