Ls(1) now caches login (or group) names to speed up `ls -l' in directories
with files owned by several users (like /tmp).  When run on a moderately
busy system, it typically runs at twice the speed for /tmp.

At the same time, the code was changed to use several library routines
including the directory scanning routines, mtorwx(3) and warning(3) and
error(3).  The use of the last two results in slightly different, but
more informative diagnostics.  The use of the directory scanning routines
was not suitable for the `-f' option, so ls now punts to bls(1) for
this function.

Stay tuned for an even better caching scheme.
