svn diff for changed kernel files

We use longer usernames for FTP/SSH logins within our webhosting cluster and
have manually been patching this to the kernel source tree for several years
now. It has not caused any instability even under heavy concurrent connections.

The attached diffs double the size of ut_user (include/utmpx.h) and MAXLOGNAME
(sys/sys/param.h)
