Subject: bus: sync with kdbus.git (ABI break)
X-Git-Tag: v219.0~621
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=00d053d3cacab6628405d704c5049274e1be297e

bus: sync with kdbus.git (ABI break)

This syncs up the new KDBUS_CMD_CONN_INFO behavior:
 - attach-flags are passed in .attach_flags, instead of directly merged
   with the command flags.
