catch Bluetooth AVRCP media keys and route to mpv if running

Browse Source 
grabkeys() now iterates the full keymap and grabs every keycode that
maps to each bound keysym, instead of relying on XKeysymToKeycode which
returns only one. Bluetooth headsets (e.g. Jaybird X2 AVRCP) register as
a second keyboard with their own keycodes for XF86AudioPlay/Next/Prev,
so the single-keycode grab missed them.

The media-key bindings now try pauseallmpv first (per-instance IPC
control of any running mpv) and fall back to mpc when no mpv socket is
reachable.
