upstream commit

Replace <sys/param.h> with <limits.h> and other less
 dirty headers where possible.  Annotate <sys/param.h> lines with their
 current reasons.  Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1,
 LOGIN_NAME_MAX, etc.  Change MIN() and MAX() to local definitions of
 MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution.
 These are the files confirmed through binary verification. ok guenther,
 millert, doug (helped with the verification protocol)
