Patch: Prepare for some cleanups of 802.11ad

[Richard Sharpe <realrichardsharpe () gmail com>]

Hi folks,

As part of fixing some problems in the 802.11ad dissector that I am
aware of I want to define some constants and a convenience macro in
wiretap/wtap.h.

Here are the first changes. If anyone has any criticisms let me know.
I will likely push this to Gerrit later in the weekend.
