Add notes about userspace ABI/API modifications, including the
fact that we decided that API submissions should come with a
driver implementation.

* This header file defines the userspace API to the wireless stack. Please
* be careful not to break things - i.e. don't move anything around or so
* unless you can demonstrate that it breaks neither API nor ABI.
* Additions to the API should be accompanied by actual implementations in
* an upstream driver, so that example implementations exist in case there
* are ever concerns about the precise semantics of the API or changes are
* needed, and to ensure that code for dead (no longer implemented) API
* can actually be identified and removed.
* Nonetheless, semantics should also be documented carefully in this file.
