Sanitize obsolete modprobe and udev rules during upgrades, unload the removed module when possible, and expand Bluetooth diagnostics for stale configuration. Continues the cleanup for #44 and #53.
This branch already switched to standard btusb (commit 86aa95f), but
several pieces still pointed back at the removed aic_btusb module:
- drivers/aic8800/aic_btusb/ source tree (no longer in build)
- modprobe/aic8800-bt.conf installed to /etc/modprobe.d/, which
softdep'd btusb to a nonexistent aic_btusb and aliased AIC BT
interfaces to it. This caused btusb to load without firmware
having been uploaded, producing HCI_Reset timeout -110 on hci0.
- install.sh still copied that conf into /etc/modprobe.d/
- diagnose_bt.sh still told users to modprobe aic_btusb
diagnose_bt.sh rewritten to flag the residual /etc/modprobe.d/aic8800-bt.conf
on already-installed systems and to advise the correct flow
(aic_load_fw uploads BT firmware, btusb takes over).
