Created subrequest pointer in RepackRequest serialization.
Created initial scheduler database repack request.
Removed duplicate function in Scheduler.

This will prevent trim-against-create fights between 2 processes where a process
trying to create a new queue to push abandons after 5 retries.

Conflicts:
	scheduler/SchedulerTest.cpp

RequestMessage::processTape_Ch() now calls m_catalogue.modifyTapeMediaType() and m_catalogue.modifyTapeVendor() so that 'cta-admin tape ch' now supports '--mediatype' and '--vendor'

Upgraded to EOS 4.4.18-20181211213834git95c105 in order to get a version of EOS that uses v0.29 of xrootd-ssi-protobuf-interface which provides the renewable resources option

Upgraded to EOS 4.4.18-20181211164351git06ae732 in order to get fixes for FSTs not reporting failed close calls when used with CTA and for problems with prepare permissions

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

This promotion is controlled so that only a limited number a requests
are in the
state ToExpand or Starting at any point in time. This ensures both the
availabality
of repack file requests to system while preventing an explosion of file
level requests.

Created a one-round popping from the container (algorithms) with status
switching.
  - Used for repack requests switching from pendig to to expand

Added ElementStatus to algorithms.

Implemented promotion interface in Scheduler and OstoreDb. The actual
decision is taken at
the Scheduler level. The function itself is called by the
RepackRequestManager.

Promotion is tested in a unit test.

Various code maintenance:
Switched to "using"-based constructor inheritance.
Fixed privacy of function in cta::range.

Upgraded to EOS 4.4.17-20181204103742gitf66a3fa for added crosstalk protection between EOS/CTA instances and to have an FST that does not send the MGM close and sync::close events

Revert "Replaced the configuration of the asynchronous sys.workflow.closew.retrieve_written event with the synchronous one, i.e. sys.workflow.sync::closew.retrieve_written"

This reverts commit d591b0de.

Replaced the configuration of the asynchronous sys.workflow.closew.retrieve_written event with the synchronous one, i.e. sys.workflow.sync::closew.retrieve_written

The archive_failed and retrieve_failed events between the CTA tape server and EOS are now synchronous

Added chown daemon:root /var/eos/config to continuousintegration/docker/ctafrontend/cc7/opt/run/bin/ctaeos-mgm.sh

Corrected buildtree_runner/README.md by puttting 'sudo' in front of ./recreate_buildtree_running_environment.sh

Added the yum-plugin-versionlock package to continuousintegration/buildtree_runner/vmBootstrap/bootstrapSystem.sh

Added the manually specified cmake variable named NoAcs.  Please note that this variable currently has no effect when building the CTA rpms

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

Removed the need for a deferred transaction from SQLiteCatalogue::getNextArchiveFileId() and getNextStorageClassId()

Moved autocommitMode parameter from Stmt constructor to Stmt::executeQuery() and Stmt::executeNonQuery()
