In OSD2r05 draft each attribute list element header was changed
so attribute-value would be 8 bytes aligned. In OSD2r01-r04
it was aligned on 2 bytes. (This is because in OSD2r01 the complete
element was 8 bytes padded at end but the header was not adjusted
and caused permanent miss-alignment.)
OSD1 elements are not padded and might be or might not be aligned.
OSD1 is still supported.
In this code we do all the code re-factoring to separate OSD1/OSD2
differences but do not change actual wire format. All wire format
changes will happen in one patch later, for bisect-ability.

Add support for OSD2 at run time. It is now possible to run with
both OSDv1 and OSDv2 targets at the same time. The actual detection
should be preformed by the security manager, as the version is encoded
in the capability structure.
