winedbg & output functions

[Eric Pouech]

this patch mainly gets rid of all ugly winedbg internals for printing... 
and use either pure Win32 console output or wine regular debug channels 
for all other outputs

ChangeLog:
- get rid of winedbg internal channels for output
- move all standard (old MESG channel) output to stdout
- move all other outputs (TRACE, WARN...) to a new wine debugging 
channel (winedbg)
- replaced quite a few #ifdef:ed out output to new channels (mainly in 
symbol management area...)
- added a new maintenance commands to ease up debugging
- updated documentation accordingly

A+
