Microsoft SoH Support

Thanks to a lot of work by Phil Mayers, the server now has support for Microsoft SoH in PEAP, normal RADIUS (MS VPN gateway), and in DHCP. The code is in the "v2.1.x" branch, and in the "stable" branch. It will be in 2.1.11, and all later versions of the server. The documentation is in doc/SoH.txt, and in raddb/sites-available/soh. The EAP configuration in eap.conf can also be updated to enable SoH on the server side. See http://git.freeradius.org/ for information on git. Alan DeKok.
