Delete openscreen backend. The environment variable ADB_MDNS_OPENSCREEN no longer has any effect. The only mDNS backend is libadbmdns.
Add trace level. ADB_TRACE format now accepts a log level (for example: usb:v, services:w).
Linux: Improve USB hotplug system. Rely on udev netlink events instead of kernel to avoid race conditions with udev.
Add blame for the kill-server command. The adb server will print out the process command line chain which requested its termination.
Windows: Improve mDNS backend. Load wlanapi.dll lazily to allow adb to run on Windows Server that doesn't include wlanapi.dll.
Introduce libadbusb to replace libusb. libadbusb can be disabled by setting the ADB_USB_LEGACY environment variable to 1.
MacOS: Disable libusb. Use legacy USB backend instead. libusb can be enabled by setting the ADB_LIBUSB environment variable to 1.
