Added MEDIA_TYPE and VENDOR columns to TAPE table and upgraded xrootd-ssi-protobuf-interface to v0.29

DataTransferSessionTapeFullMigration and DataTransferSessionTapeFullOnFlushMigration now count the first files archived to tape as opposed to relying on the values of the archive file IDs

The tape write task not lister anymore to the memory manager for zero length files.

A retry might sneak into the session (depending of end of sessions and reporting speeds).
Relaxed the test criteria for this case.

We now leave a placeholder on the tape and carry on in this case. The errors will eventually clear the
archive request.

The disk read task hangs in this case. The tape write taks is still created, will leave a placeholder on the
tape (to be implemented) and count an error for the request.

Modified CMakeLists.txt files to apply -Wno-unused-function for GCC 6 and above.  It was GCC 7 and above before.

This setup allows reproducing a but seen in system tests.

This is validated in a unit test.

The catalogue can receive polymorphic items as input for recording.
The strict sequencing of fSeqs is still enforced.
Currently, 2 items types are recorded: files and placehoders.
Files are recorded to the tape catalogue, while place holders are not,
but they are used to enforce the fSeq sequencing.

When no data is received for a given file, the tape server will
leave a placeholder on tape an carry on with the writing of the
following files, avoiding a tape unmount.

Updated unit test.

This should ease the contention on the object store.

The error(s) gets recorded at failure time, and the list is printed at
job deletion time.

This version is not data safe as the request is created late, right after
referencing the job to the queue.

The top half goes as far as when the request is safe in the object store.
At that point, the bottom half is launched in a new thread, and success is returned
the called. This will enable lower latency for the users while retaining
the same data safety.

This version is experimental aas it spans an undetermined number of threads. A more controlled
version with a work queue should be implenented on the long run.

This allows attaching a debugger to the main process.

Moved SourcedParameter<FetchReportOrFlushLimits>::set() from SourcedParameter.cpp to TapedConfiguration.cpp

SourcedParameter.cpp is the "common" CTA directory, in other words
CTA/commIit is located at on/SourcedParameter.cpp.  The
SourceParameter.cpp file should therefore not contain any code
specific to a particular CTA daemon such as cta-taped.

The jobs will now remain attached to the agent of the drive process. The garbage collector
process will now requeue them instead of drive process. This will allow the drive process
to restart faster for a new session and the drive process to requeue the jobs faster a it
processes jobs in bulk.

Successful retrieve requests are asynchronously deleted as soon as they
are complete. Then from time to time (every 500), the requests get removed from
process ownership in bulk.
