Subject: [PATCH] Bug 871: Rework construction of Wi-Fi rates

This patch attempts to lay some groundwork for enhancements to the Wi-Fi module
by bringing the representation of transmit rates more in line with the
standard.

The key part of the patch is the introduction of a type that corresponds to the
notion of Modulation Class described in IEEE 802.11-2007, Section 9.6.1, Table
9-2.

It also adds coding rate information to the WifiModes and centralises their
construction into a single WifiModeFactory method. The rates are also renamed
with reference to their Modulation Class.

WifiModes no longer have a WifiStandard, but the latter type still exists and is
used to imply the set of WifiModes that a MAC/PHY pair will support.

+     been undertaken with the aim of simplifying the task of
+     supporting further IEEE 802.11 PHYs. This work has been completed
+     under the auspices of Bug 871. A consequence of this work is that

+     simulations which specify rates by name will need updating. The
