Replaced the map of tape files with a list as the assumption that we have one copy per copyNb is no more valid with repack.

Modified MysqlCatalogue.cpp to use autocommitMode default of Stmt::executeQuery() and Stmt::executeNonQuery()

Modified RdbmsCatalogue to use autocommitMode default of Stmt::executeQuery() and Stmt::executeNonQuery()

Please note that OracleCatalogue::filesWrittenToTape() now updates the TAPE
table row with AUTOCOMMIT_ON before going on to handle the individual file
entries.  This can be improved when Conn:setAutocommit() becomes available.

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

This reverts commit 613808d9.

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

This reverts commit 8f7bd42f.

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

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

Renamed rdbms::AutocommitMode::ON and rdbms::AutocommitMode::OFF to rdbms::AutocommitMode::AUTOCOMMIT_ON and rdbms::AutocommitMode::OFF respectively

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.

cta/CTA#212 Verify the tape catalogue enforces the rule that all tape copies have the same file size and checksum.

Fixed.

Moved maxTriesToConnect parameter to CatalogueFactory::create().

Done

This commit does two things.  Firstly it puts back the call from:

    XrdCtaFile::xCom_deletearchive()

to:

    Scheduler::deleteArchive()

Secondly it moves the reponsibility of logging the
"Archive File Deleted" message from the CTA front-end (XrdCtaFile)
to the CTA catalogue.

Please note that Scheduler::deleteArchive() still does not call
SchedulerDatabase::deleteArchiveRequest().
