46f1d17c74 libdm: implement search for device names for older kernels 
Kernels <2.6.27 don't have /sys/dev dir - add code for looking
out device name via longre seach in /sys/block

This makes commands like 'dmsetup dep -o blkdevname' working.

I wrote dbg_malloc before we had valgrind.  These days there's just
no need.

ccc35e2647 device-mapper: Fork libdm internally. 
The device-mapper directory now holds a copy of libdm source.  At
the moment this code is identical to libdm.  Over time code will
migrate out to appropriate places (see doc/refactoring.txt).

The libdm directory still exists, and contains the source for the
libdevmapper shared library, which we will continue to ship (though
not neccessarily update).

All code using libdm should now use the version in device-mapper.
