Add type checking for static and dynamic sysctls using scalar types.

The code is turned off until the tree is fixed up so it compiles.
__FreeBSD_version was already bumped once today, so skip the bump, but
add an entry to UPDATING.

Note that __DESCR() is used in the SYSCTL_OID() macro and so is not
needed in macros that invoke it.  This use was inconsistent in the
file and I have made it consistent any lines already being changed.
