* add new field "read_only" to memory blocks * add new API function pa_context_get_server() * filter capture data through mcalign on client * make module-tunnel use pa_socket_client_new_string() instead of using pa_resolve_server() directly. * remove pa_resolve_server() * remove debug.h and replace it by a macro definition on the gcc command line * some strbuf cleanups * small fixes in pa_stream for cleanup when server dies * new CLI command "load-sample-dir-lazy" * send FQDN as part of server info * rework mcalign, this time with memory block merging * fix iochannel cleanup when connection dies * check getaddrinfo() results git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@286 fefdeb5f-60dc-0310-8127-8f9354f1896f
