* uri.c parser.c: some warning removal on Igor's patch
* tree.c: seems I messed up with #106788 fix
* python/libxml.c: fixed some base problems when Python provides
  the resolver.
* relaxng.c: fixed the interleave algorithm
  found 373 test schemas: 364 success 9 failures
  found 529 test instances: 525 success 4 failures
  the resulting failures are bug in the algorithm from 7.3 and
  lack of support for params
