This patch replaces some non-inclusive terms based on the appropriate
language mapping table compiled by the Bluetooth SIG:
https://specificationrefs.bluetooth.com/language-mapping/Appropriate_Language_Mapping_Table.pdf
Specifically, these terms are replaced:
master -> initiator
slave -> responder

When an MGMT_EV_DEVICE_CONNECTED event is reported back to the user
space we will set the flags to tell if the established connection is
outbound or not. This is useful for the user space to log better metrics

An issue was found, where if a bluetooth client requests a broadcast
advertisement with scan response data, it will not be properly
registered with the controller. This is because at the time that the
hci_cp_le_set_scan_param structure is created, the scan response will
not yet have been received since it comes in a second MGMT call. With
empty scan response, the request defaults to a non-scannable PDU type.
On some controllers, the subsequent scan response request will fail due
to incorrect PDU type, and others will succeed and not use the scan
response.
This fix allows the advertising parameters MGMT call to include a flag
to let the kernel know whether a scan response will be coming, so that
the correct PDU type is used in the first place. A bluetoothd change is
also incoming to take advantage of it.
To test this, I created a broadcast advertisement with scan response
data and registered it on the hatch chromebook. Without this change, the
request fails, and with it will succeed.

For advertising, we wish to know the LE tx power capabilities of the
controller in userspace, so this patch edits the Security Info MGMT
command to be more generic, such that other various controller
capabilities can be included in the EIR data. This change also includes
the LE min and max tx power into this newly-named command.
The change was tested by manually verifying that the MGMT command
returns the tx power range as expected in userspace.

This patch adds support for the new advertising add interface, with the
first command setting advertising parameters and the second to set
advertising data. The set parameters command allows the caller to leave
some fields "unset", with a params bitfield defining which params were
purposefully set. Unset parameters will be given defaults when calling
hci_add_adv_instance. The data passed to the param mgmt command is
allowed to be flexible, so in the future if bluetoothd passes a larger
structure with new params, the mgmt command will ignore the unknown
members at the end.
This change has been validated on both hatch (extended advertising) and
kukui (no extended advertising) chromebooks running bluetoothd that
support this new interface. I ran the following manual tests:
- Set several (3) advertisements using modified test_advertisement.py
- For each, validate correct data and parameters in btmon trace
- Verified both for software rotation and extended adv
Automatic test suite also run, testing many (25) scenarios of single and
multi-advertising for data/parameter correctness.

Emit controller suspend and resume events when we are ready for suspend
and we've resumed from suspend.
The controller suspend event will report whatever suspend state was
successfully entered. The controller resume event will check the first
HCI event that was received after we finished preparing for suspend and,
if it was a connection event, store the address of the peer that caused
the event. If it was not a connection event, we mark the wake reason as
an unexpected event.
Here is a sample btmon trace with these events:
@ MGMT Event: Controller Suspended (0x002d) plen 1
Suspend state: Page scanning and/or passive scanning (2)
@ MGMT Event: Controller Resumed (0x002e) plen 8
Wake reason: Remote wake due to peer device connection (2)

For new advertising features, it will be important for userspace to
know the capabilities of the controller and kernel. If the controller
and kernel support extended advertising, we include flags indicating
hardware offloading support and support for setting tx power of adv
instances.
In the future, vendor-specific commands may allow the setting of tx
power in advertising instances, but for now this feature is only
marked available if extended advertising is supported.
This change is manually verified in userspace by ensuring the
advertising manager's supported_flags field is updated with new flags on
hatch chromebook (ext advertising supported).

Currently it is not possible to determine if the static address is used
by the controller. It is also not possible to determine if using a
static on a dual-mode controller with disabled BR/EDR is possible or
not.
To address this issue, introduce a new setting called static-address. If
support for this setting is signaled that means that the kernel supports
using static addresses. And if used on dual-mode controllers with BR/EDR
disabled it means that a configured static address can be used.
In addition utilize the same setting for the list of current active
settings that indicates if a static address is configured and if that
address will be actually used.
With this in mind the existing Set Static Address management command
has been extended to return the current settings. That way the caller
of that command can easily determine if the programmed address will
be used or if extra steps are required.
