I deem branch ts-cdtext-fix ready for inclusion.

The ABI compatible variant of multi-extent still has to be developed.

By introducing a new "v2" API part, it should be possible to avoid breaking
the ABI of the existing iso0660_stat "v1" API and ABI.

Yeah. "Gol da alemanha !". What glorious times.

Yes. That's the plan.

In my own scheme of .so numbering, the current development would be
  libcdio.so.18.1.0
  libiso9660.so.11.1.0
with the warning that the newly introduced parts of this API are still
prone to changes.

The next release would then install
  libcdio.so.18.2.0
by
  libcdio_la_CURRENT = 20
  libcdio_la_REVISION = 2
  libcdio_la_AGE = 0
and
  libiso9660.so.11.2.0
by
  libiso9660_la_CURRENT = 13
  libiso9660_la_REVISION = 2
  libiso9660_la_AGE = 0
with the promise that the new API parts will be kept stable in future.


It will probably last a few days until my proposal of iso9660_statv2 is
ready. Then it will need heavy testing.
(I could reduce the risk of regressions by leaving the old iso9660_stat
 implementation as is and using a copy of it for deriving v2. But that
 would lead to ugly code duplication and future maintainance pitfalls.)


Have a nice day :)
