If a controller is powered on while the HCI_AUTO_OFF flag is set the
link security setting (HCI_LINK_SECURITY) might not be in sync with the
actual state of the controller (HCI_AUTH). This patch fixes the issue by
checking for inequality between the intended and actual settings and
sends a HCI_Write_Auth_Enable command if necessary.

We will need to create three separate UUID lists in the EIR data (for
16, 32 and 128 bit UUIDs) so the code is easier to follow if each list
is generated in their own function.

The amount of data encoded so far in the create_eir() function can be
calculated simply through the difference between the data and ptr
pointer variables. The eir_len variable then becomes essentially
useless.

There's no need to use two separate loops to generate a UUID list for
the EIR data. This patch merges the two loops previously used for the
16-bit UUID list generation into a single loop, thus simplifying the
code a great deal.

The primary purpose of the UUIDs is to enable generation of EIR and AD
data. In these data formats the UUIDs are split into separate fields
based on whether they're 16, 32 or 128 bit UUIDs. To make the generation
of these data fields simpler this patch adds a type member to the
bt_uuid struct and assigns a value to it as soon as the UUID is added to
the kernel. This way the type doesn't need to be calculated each time
the UUID list is later iterated.

We should be encoding UUIDs to the EIR data in the same order that they
were added to the kernel, i.e. each UUID should be added to the end of
the UUIDs list. This patch fixes the issue by using list_add_tail
instead of list_add for storing the UUIDs.

The LE supported states indicate the states and state combinations that
the link layer supports. This is important information for knowing what
operations are possible when dealing with multiple connected devices.
This patch adds reading of the supported states to the HCI init

To be able to make the appropriate decisions for some LE procedures we
need to know the LE features that the local controller supports.
Therefore, it's important to have the LE Read Local Supported Features

The Block/Unblock Device Management commands should return Command
