OK, I've had lots of people ask for my install patches, so here they
are.  I've included four patches.  The first two are for xinstall.c
and install.1 (the man page).  These can stand by themselves if you
just want the functionality.

In order to make it so your libraries don't get new times each
time you install them, and instead keep the time/date of when they
were last compiled, you need two additional patches, which are the
last two included below.  The bsd.own.mk patch simply adds the -p flag
to the COPY variable (which is kind of a perversion, but if people
think this is worthwhile, I'll take time and fix it right).

The bsd.lib.mk patch adds a command to touch the installed library
with the time from the one in your obj dir.  I discovered while
playing with all this that the installation runs a ranlib on the
library after installing it anyway, nullifying the effect of install
-p in this case.  So, I added a touch as the last thing after
installing a library so it looks like it was last modified when it was
last compiled, even though the SYMDEF table gets updated with the
current time.  Since the SYMDEF time is newer, I don't think this
should cause any problems anywhere.

Remember you have to patch the files in src/share/mk if you want the
last two patches to stick through a build.  Feedback on all this much
encouraged.  Here's the stuff:
