In sudo 1.8.4 the UCB fnmatch.c has been replaced with a non-recursive
BSD-licensed version that is copyright VMWare (the same version is
now being used by apr).  Note that this is only used on systems
without a proper fnmatch(), the fnmatch() in glibc is fine.

The missing redblack.c license was an omission on my part dating
back to sudo 1.7.

The main sudo license is still ISC and the other parts are (new)
BSD-style licenses.
