This fixes the count of Adv monitor upon monitor removal.

console and observe a MGMT_EV_ADV_MONITOR_REMOVED event on the other.

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)

Here we make sure we properly report the number of supported
advertising slots when we are using hardware offloading. If no
hardware offloading is available, we default this value to
HCI_MAX_ADV_INSTANCES for use in software rotation as before.
This change has been tested on kukui (no ext adv) and hatch (ext adv)
chromebooks by verifying "SupportedInstances" shows 5 (the default) and
6 (slots supported by controller), respectively.

For some reason they tend to squat on the very first CSR/
Cambridge Silicon Radio VID/PID instead of paying fees.
This is an extremely common problem; the issue goes as back as 2013
and these devices are only getting more popular, even rebranded by
reputable vendors and sold by retailers everywhere.
So, at this point in time there are hundreds of modern dongles reusing
the ID of what originally was an early Bluetooth 1.1 controller.
Linux is the only place where they don't work due to spotty checks
in our detection code. It only covered a minimum subset.
So what's the big idea? Take advantage of the fact that all CSR
chips report the same internal version as both the LMP sub-version and
HCI revision number. It always matches, couple that with the manufacturer
code, that rarely lies, and we now have a good idea of who is who.
Additionally, by compiling a list of user-reported HCI/lsusb dumps, and
searching around for legit CSR dongles in similar product ranges we can
find what CSR BlueCore firmware supported which Bluetooth versions.
That way we can narrow down ranges of fakes for each of them.
e.g. Real CSR dongles with LMP subversion 0x73 are old enough that
support BT 1.1 only; so it's a dead giveaway when some
third-party BT 4.0 dongle reuses it.
So, to sum things up; there are multiple classes of fake controllers
reusing the same 0A12:0001 VID/PID. This has been broken for a while.
Known 'fake' bcdDevices: 0x0100, 0x0134, 0x1915, 0x2520, 0x7558, 0x8891

When scheduling TX packets, send all SCO/eSCO packets first, check for
pending SCO/eSCO packets after every ACL/LE packet and send them if any
are pending. This is done to make sure that we can meet SCO deadlines
on slow interfaces like UART.
If we were to queue up multiple ACL packets without checking for a SCO
packet, we might miss the SCO timing. For example:
The time it takes to send a maximum size ACL packet (1024 bytes):
t = 10/8 * 1024 bytes * 8 bits/byte * 1 packet / baudrate
where 10/8 is uart overhead due to start/stop bits per byte
Replace t = 3.75ms (SCO deadline), which gives us a baudrate of 2730666.
At a baudrate of 3000000, if we didn't check for SCO packets within 1024
bytes, we would miss the 3.75ms timing window.

This commit makes the kernel not send the next queued HCI command until
a command complete arrives for the last HCI command sent to the
controller. This change avoids a problem with some buggy controllers
(seen on two SKUs of QCA9377) that send an extra command complete event
for the previous command after the kernel had already sent a new HCI
command to the controller.
The problem was reproduced when starting an active scanning procedure,
where an extra command complete event arrives for the LE_SET_RANDOM_ADDR
command. When this happends the kernel ends up not processing the
command complete for the following commmand, LE_SET_SCAN_PARAM, and
ultimately behaving as if a passive scanning procedure was being
performed, when in fact controller is performing an active scanning
procedure. This makes it impossible to discover BLE devices as no device
found events are sent to userspace.
This problem is reproducible on 100% of the attempts on the affected
controllers. The extra command complete event can be seen at timestamp
27.420131 on the btmon logs bellow.
