rawmidi devices expose the card number via IOCTLs, which allows to find the corresponding device in sysfs.
The sequencer provides no identifing data. Chromium works around this issue by scanning rawmidi as well as sequencer devices and matching them by using assumtions, how the kernel register sequencer devices.
This patch adds support for displaying the sound card number/PID to aconnect.

This patch alone would break the build if alsa-utils is built against the alsa-lib without your patch. So some check is needed.
