Pre-release of Version 2.1.8

[Alan DeKok]

  I've put a pre-release of version 2.1.8 on the web site:

http://git.freeradius.org/pre/

  Please do some sanity checks, and see if it works for you.

  This version is from the new "v2.1.x" branch, which is Version 2.1.7,
plus *only* bug fixes.  The "stable" branch is now planned to become
version 2.2.0 in January.  It will include TCP transport, among other
new features.

  If there are no major issues, we can release 2.1.8 next week.
