Add linux-topology topic branch 

Solaris recently introduced the idea of drive topology because
where a drive is located does matter.  I have already handled
this with udev/blkid integration under Linux so I'm hopeful
this case can simply be removed but for now I've just stubbed
out what is needed in libspl and commented out the rest here.

From: Brian Behlendorf <behlendorf1@llnl.gov>
Subject: [PATCH] zfs branch
Subject: [PATCH] linux topology
Merged result of all changes which are relevant to both Solaris
and Linux builds of the ZFS code. These are changes where there
is a reasonable chance they will be accepted upstream.
Additionally, since this is effectively the root of the linux
ZFS tree the core linux build system is added here. This
includes autogen.sh, configure.ac, m4 macros, some scripts/*,
and makefiles for all the core ZFS components. Linux-only
features which require tweaks to the build system should appear
on the relevant topic branches. All autotools products which
result from autogen.sh are commited to the linux-configure-branch.
This branch also contains the META, ChangeLog, AUTHORS, TODO,
and README, files.
