xfs: Enable -Werror, fix all warnings

Define a dedicated OnDiskData structure for each on-disk structure. This
must match the on-disk layout, except for endianness, which is handled
by _SwapEndian methods. These structure are "plain old data" so we can
use offsetof on them. They are wrapped in an easier to use C++ API.

This resolves a lot of problems with the previous code: warnings caused
by the use of offsetof as well as a much simpler instanciation of the
objects from on-disk data.

Also fixed another problem with UUIDs, where the UUIDs were handled by
pointers in a lot of place where it was not necessary. Use references
instead. The V4 structures which don't have an UUID will return a "null"
(zero-filled) one.
