When accepting a pairing request which fulfills the SSP auto-accept
criteria we need to push the request all the way to the user for
confirmation. This patch adds a new hint to the user_confirm_request
management event so user space can know when to show a numeric
comparison dialog and when to show a simple yes/no confirmation dialog.

Some test systems require an arbitrary delay to the auto-accept test
cases for Secure Simple Pairing in order for the tests to pass.
Previously when this was handled in user space it was worked around by
code modifications and recompilation, but now that it's on the kernel
side it's more convenient if there's a debugfs interface for it.

This patch adds automated negative and positive (auto-accept) responses
for Secure Simple Pairing user confirmation requests. The responses are

High security level for pre v2.1 devices requires combination link key
authenticated by at least 16 digit PIN code.
It's also necessary to update key_type and pin_length when the key
exists and is sufficently secured for the connection as there will be
no link key notify event in that case.

If authentication fails the security level should stay as it was set
before the process has started. Setting BT_SECURITY_LOW can hide real
security level on a link eg. having BT_SECURITY_MEDIUM on the link,
re-authenticate with failure to get BT_SECURITY_HIGH, as a result we
get BT_SECURITY_LOW on the link while the real security is still medium.

This patch adds start_discovery and stop_discovery commands to the
management interface. Right now their implementation is fairly
simplistic and the parameters are fixed to what user space has
defaulted to so far.
This is the very initial phase for discovery implementation into
the kernel. Next steps include name resolution, LE scanning and
bdaddr type handling.

The locking with SMPS requests means that the
debugs file should lock the mgd mutex, not the
iflist mutex. Calls to __ieee80211_request_smps()
need to hold that mutex, so add an assertion.
This has always been wrong, but for some reason
never been noticed, probably because the locking
error only happens while unassociated.

In the teardown path the reset command is sent to the controller,
this event causes the command timer to be reactivated.
So the timer is removed in two situations, when the adapter isn't
marked as UP and when we know that some command has been sent.
