liba2dp: Fix timeout computation in wait_for_start()HEADandroid-sdk-tools_r2android-sdk-1.6_r2android-sdk-1.6_r1android-sdk-1.6-docs_r1android-1.6_r2android-1.6_r1.5android-1.6_r1.4android-1.6_r1.3android-1.6_r1.2android-1.6_r1.1android-1.6_r1mastermaindonut-release2donut-releasedonut

Also increase a2dp_write timeout from 100ms to 500 ms
to avoid losing the first fraction of a second of a song
when streaming starts.
