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
