Finding typos using codespell

[Bruce Cran]

There's a new tool that can be used to find spelling mistakes in code: codespell 
from http://www.politreco.com has already been used to find mistakes in both 
Linux and LLVM. I ran it on sys/ and it found lots of potential typos - the 
full diff (which I know does contain some incorrect changes) can be found at 
http://www.cran.org.uk/~brucec/freebsd/codespell_sys.diff .
