manual name request when a new connection gets created (for whatever

So far userspace has been responsible for this extra name request but
tighter control is needed in order not to flood Bluetooth controllers
with two many commands during connection creation. It has been shown
that some controllers simply fail to function correctly if they get too
many (almost) simultaneous commands during connection creation. The
simplest way to acheive better control of these commands is to move
their sending completely to the kernel side.

This patch inserts name requests into the sequence of events that the
kernel performs during connection creation. It does this after the
remote features have been successfully requested and before any pending
authentication requests are performed. The code will work sub-optimally
with userspace versions that still do the name requesting themselves (it
shouldn't break anything though) so it is recommended to combine this
with a userspace software version that doesn't have automated name
requests.
