Bump the library version numbers for the following libraries:

/lib/{libm,libreadline}
	/usr/lib/{libhistory,libopie,libpcap}

in preparation for doing the same thing to RELENG_5.  HUGE amounts of
help for determining what to bump provided by kris.

Discussed on:	freebsd-current
Approved by:	re (not required for commit but something like this should be)

+20041001:
+	The following libraries had their version number bumped up:
+		/lib/libm.so.2 -> libm.so.3
+		/lib/libreadline.so.4 -> libreadline.so.5
+		/usr/lib/libhistory.so.4 -> libhistory.so.5
+		/usr/lib/libopie.so.2 -> libopie.so.3
+		/usr/lib/libpcap.so.2 -> libpcap.so.3
+	FreeBSD 4.10 versions of these libraries will be added to the
+	compat4x collection.  If you expect to be able to run old 4.X
+	executables you will need to remove the old versions of these
+	libraries.  However note that any 5.X executables you have built
+	will stop working once you remove those old libraries.  You should
+	have all your ports/packages rebuilt before removing the old
+	libraries.

 	The pfil API has gained an additional argument to pass an inpcb.
 	You should rebuild all pfil consuming modules: ipfw, ipfilter
