Added the ArchiveForRepack mountType to the Drive reporting
Transformed the DataTransferSession::mountTypeToString() to add the ArchiveForRepack mountType, transformed the normal "Archive" into "ArchiveForUser"

Update cta::Catalogue::tapeMountedForRetrieve and
cta::Catalogue::tapeMountedForArchive to increase read/write
mount counts.

Add isFromCastor field to the catalogue DB.

CTA only sets this filed to false and respects it in the getTapesForWriting

Sets the ChecksumBlob from the supplied protocol buffer, unless the
protobuf is invalid, in which case it uses the supplied Adler32 checksum
instead.

- Removes assumption that if we have a valid checksumBlob it must
  contain an ADLER32 checksum. (Some of the unit tests have MD5
  checksums only).

tapes

Add read-only tape flag support in the catalogue for the TAPE table.
Add RdbmsCatalogue::setTapeReadOnly method to modify this flag with
  "cta-admin tape ch" command.
Add RdbmsCatalogue::setTapeReadOnlyOnError to set this flag from taped.
Add support for rdonly flag listing for "cta-admin tape ls" and
  "cta-admin sq" command.

Mostly changes to new unit tests.

It isn't necessary to serialize the protobuf to compute the serialized
length, use ByteSizeLong() instead.

Adds support for byte array columns in the DB. Implementation done for
SQLite, the others are placeholders.

- Type of checksumBlob in cta.proto should be bytes not string
- ADLER32 passed into blob as uint32_t not string (conversion to
  bytearray is now handled inside the ChecksumBlob class)

The blob is a set of type/value pairs which can be serialised to a byte
array for storage in the DB.

Redundant as it is always the same as totalBytes

* TapeFile::compressedSize is renamed to fileSize
* TapeFileWritten::compressedSize is removed, as it contains the same
  information as TapeFileWritten::size
