bum version number
add new macro PA_API_VERSION for preprocessor level conditional compiling add new native APIs: - counter - cork & flush for record streams - add flags parameters to pa_stream_connect_xx() - new prebuf command - time api, and total latency calculator - return sample spec ability to cork source output streams dump server status on SIGHUP to syslog show sink input/source outputs status in cli-text.c don't flush esound output buffer when client disconnects move version api to polyplib-version.h git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@240 fefdeb5f-60dc-0310-8127-8f9354f1896f
