Some printfs and other instrumentation to improve resync of muroad.
merged bugfix when removing render clients to branch
added some cmake packages
merged some changes from master
added log4cplus config file
fixed a sync error (typo in name of audio device in one out of two
places, it should be just on place)
Merge branch 'sync-fix' of ssh://github.com/martinrunge/muroa into sync-fix

Conflicts:
	.gitignore
	aux/cmake/arm-ct-ng-cross.cmake
	libstreamsrv/.cproject
	muroad/cplayloop.cpp
	muroad/log.properties
add .gitignore to resamplertest
why does .gitignore nor ignore .wav and .png files?

it was a tailing space :-(
stream can be started. Balanced out soundcard buffer size and num
periods to store there before start.
starting a fresh stream is now pretty much in shape. Nearly no crank
sound.
further sync improvements: start muroad while stream is running and case
of buffer underrun (still needs improvement)
starting and restarting a stream and playing in sync works well.
code cleanup
Adding and removing render clients from the GUI working again.
Sync fixes applied to a large degree, prepare to merge back.
