Add empty udev rule to disable hid2hci by default

Add empty udev rule to disable hid2hci by default

[Alexander Holler]

Hello.

Almost every distribution gets it wrong and enables hid2hci by default 
(besides Fedora where I already intervened twice).

This is a real problem, because it disables Bluetooth keyboards and/or 
mice which aren't paired with bluez, thus many Live-CDs and default 
installs aren't usable when only a Bluetooth keyboard is connect.

An easy solution to disable that behaviour would be to install an empty 
rule in /etc/udev/rules.d named the same as the one in 
/lib/udev/rules.d. It could just contain a comment like

# Delete this file in order to activate hid2hci.
#
# You might need to pair your Bluetooth keyboard and/or mouse
# in order to still use it when hid2hci is enabled.

This (empty) rule would then be used by udev instead of the one in 
/lib/udev/rules.d and thus would be an easy to use configuration switch.

I would appreciate it, if the default bluez install would install such 
an empty rule too, if configure was called with --enable-hid2hci.

I think otherwise that problem will never go away. It's really 
unbelievable how many distributions got this wrong and thus how many 
Live-CDs and default installations are unusable when only a Bluetooth 
keyboard is used with a hid-aware Bluetooth dongle.

Unfortunately that isn't a very practical idea, as the rule(-file) would 
likely become installed again with every upgrade or reinstall. :(

So another idea seems to be necessary to either educate distributions 
(or their package maintainers) that they should build a distinct package 
for hid2hci and don't install that package by default, or some mechanism 
which enables the user to enable/disable hid2hci (as it was the case 
before the udev-rule went to /lib),
