Bluetooth: Add support for remote OOB input of P-256 data

The current management interface only allows to provide the remote
OOB input of P-192 data. This extends the command to also accept
P-256 data as well. To make this backwards compatible, the userspace
can decide to only provide P-192 data or the combined P-192 and P-256
data. It is also allowed to leave the P-192 data empty if userspace
only has the remote P-256 data.

Bluetooth: Add support for local OOB data with Secure Connections

Bluetooth: Add support for local OOB data with Secure Connections

For Secure Connections support and the usage of out-of-band pairing,
it is needed to read the P-256 hash and randomizer or P-192 hash and
randomizer. This change will read P-192 data when Secure Connections
is disabled and P-192 and P-256 data when it is enabled.

The difference is between using HCI Read Local OOB Data and using the
new HCI Read Local OOB Extended Data command. The first one has been
introduced with Bluetooth 2.1 and returns only the P-192 data.

< HCI Command: Read Local OOB Data (0x03|0x0057) plen 0
> HCI Event: Command Complete (0x0e) plen 36
Read Local OOB Data (0x03|0x0057) ncmd 1
Status: Success (0x00)
Hash C from P-192: 975a59baa1c4eee391477cb410b23e6d
Randomizer R with P-192: 9ee63b7dec411d3b467c5ae446df7f7d

The second command has been introduced with Bluetooth 4.1 and will
return P-192 and P-256 data.

< HCI Command: Read Local OOB Extended Data (0x03|0x007d) plen 0
> HCI Event: Command Complete (0x0e) plen 68
Read Local OOB Extended Data (0x03|0x007d) ncmd 1
Status: Success (0x00)
Hash C from P-192: 6489731804b156fa6355efb8124a1389
Randomizer R with P-192: 4781d5352fb215b2958222b3937b6026
Hash C from P-256: 69ef8a928b9d07fc149e630e74ecb991
Randomizer R with P-256: 4781d5352fb215b2958222b3937b6026

The change for the management interface is transparent and no change
is required for existing userspace. The Secure Connections feature
needs to be manually enabled. When it is disabled, then userspace
only gets the P-192 returned and with Secure Connections enabled,
userspace gets P-192 and P-256 in an extended structure.

It is also acceptable to just ignore the P-256 data since it is not
required to support them. The pairing with out-of-band credentials
will still succeed. However then of course no Secure Connection will
b established.

Bluetooth: Add management command for enabling Secure Connections

The support for Secure Connections need to be explicitly enabled by
userspace. This is required since only userspace that can handle the
new link key types should enable support for Secure Connections.

This command handling is similar to how Secure Simple Pairing enabling
is done. It also tracks the case when Secure Connections support is
enabled via raw HCI commands. This makes sure that the host features
page is updated as well.

Bluetooth: Add management command for setting LE scan parameters

The scan interval and window parameters are used for LE passive
background scanning and connection establishment. This allows
userspace to change the values.

These two values should be kept in sync with whatever is used for
the scan parameters service on remote devices. And it puts the
controlling daemon (for example bluetoothd) in charge of setting
the values.

Main use case would be to switch between two sets of values. One
for foreground applications and one for background applications.

At this moment, the values are only used for manual connection
establishment, but soon that should be extended to background
scanning and automatic connection establishment.

Bluetooth: Add management command for setting static address

On dual-mode BR/EDR/LE and LE only controllers it is possible
to configure a random address. There are two types or random
addresses, one is static and the other private. Since the
random private addresses require special privacy feature to
be supported, the configuration of these two are kept separate.

This command allows for setting the static random address. It is
only supported on controllers with LE support. The static random
address is suppose to be valid for the lifetime of the controller
or at least until the next power cycle. To ensure such behavior,
setting of the address is limited to when the controller is
powered off.

The special BDADDR_ANY address (00:00:00:00:00:00) can be used to
disable the static address. This is also the default value.

Bluetooth: Add a new mgmt_set_bredr command

This patch introduces a new mgmt command for enabling/disabling BR/EDR
functionality. This can be convenient when one wants to make a dual-mode
controller behave like a single-mode one. The command is only available
for dual-mode controllers and requires that LE is enabled before using
it. The BR/EDR setting can be enabled at any point, however disabling it
requires the controller to be powered off (otherwise a "rejected"
response will be sent).

Disabling the BR/EDR setting will automatically disable all other BR/EDR
related settings.

Bluetooth: Add new mgmt_set_advertising command

This patch adds a new mgmt command for enabling and disabling
LE advertising. The command depends on the LE setting being enabled
first and will return a "rejected" response otherwise. The patch also
adds safeguards so that there will ever only be one set_le or
set_advertising command pending per adapter.

The response handling and new_settings event sending is done in an
asynchronous request callback, meaning raw HCI access from user space to
enable advertising (e.g. hciconfig leadv) will not trigger the
new_settings event. This is intentional since trying to support mixed
raw HCI and mgmt access would mean adding extra state tracking or new
helper functions, essentially negating the benefit of using the
asynchronous request framework. The HCI_LE_ENABLED and HCI_LE_PERIPHERAL
flags however are updated correctly even with raw HCI access so this
will not completely break subsequent access over mgmt.

Note that the local/remote distinction just determines which side
terminated the low-level connection, regardless of the disconnection of
the higher-level profiles.

This can sometimes be misleading and thus must be used with care. For
example, some hardware combinations would report a locally initiated
disconnection even if the user turned Bluetooth off in the remote side.
