[PATCH v8 0/28] MR6621: winebth.sys: Introduce Bluetooth driver.

[Vibhav Pant (＠vibhavp)]

This MR is the first of at least three MRs adding support for the Bluetooth stack API in Wine:

1. The winebth.sys driver, which talks to BlueZ and implements several key IOCTLs for communicating with Bluetooth devices and radios.
2. A bthserv service, which is responsible for keeping track of the authentication agent, and relaying authentication requests and responses to and from the driver.
3. Userspace APIs (bluetoothapis.dll, bthprops.cpl, Windows.Devices.Bluetooth, etc).

winebth.sys is split into two "sub" drivers:

`winebth.sys`: The main entrypoint, loaded by winedevice. It listens for changes to Bluetooth devices and radios and authentication events on BlueZ, passing them on the bthenum. It also handles most IOCTL operations on Bluetooth radio PDOs.

`bthenum`: Responsible for creating nodes for discovered Bluetooth devices and associated services. It also tries to validate any IOCTLs relating to bluetooth devices before passing them to winebth.sys.

The unix code is split between dbus.c, unixlib.c and winebluetooth.c, where winebluetooth is a simple wrapper around unixlib for the sake of organization.
