Replace XQTS with FOTS

[Chris Hillery]

When FOTS is complete from the W3C (or at least nearly complete), we need to replace our XQTS infrastructure in Zorba with FOTS. This means at least:

1. Remove XQTS download scripts.
2. Remove all the "plumbing" in CMakeLists that set up XQTS test runs.
3. Introduce new processess/scripts to generate conformance reports for FOTS.
4. Have a mechanism to run FOTS (with new XQXQ-based testdriver) on validation queue, tied in correctly to the EXPECTED_FAILURE() mechanism.

The FOTS will indeed be added to the remote queue but the old XQTS will still remain for now at least.

XQTS checks XQuery 1.0 conformance and FOTS checks the XQuery 3.0 conformance.

Marking the bug as "Won't fix".

[Sorin Marian Nasoi (sorin.marian.nasoi)]

Ghislain confirmed that all XQTS test-cases were imported into FOTS.

We need to update FOTS driver such that it can generate separate conformance reports for XQuery 1.0 and XQuery 3.0.

[Sorin Marian Nasoi (sorin.marian.nasoi)]

QT driver can create separate reports for XQuery 1.0 and XQuery 3.0.

At this moment the only reason preventing us to remove the XQTS scripts is the support for XQueryX 1.0.
XQ test-suite does not contain any XQueryX test-cases, only the old XQTS does.

Marking this issue as "Fix committed".
