Added unit-test insert_with_bindString_invalid_bool_value in order to verify check constraints are working

Fixed bug in MysqlStmt::do_bind_results() where bind[i].is_unsigned was not being set to true for uint64_t

Permanently removed the concept of rdbms::UnexpectedSemicolon.  The rdbms package should avoid trying to parse SQL, at least for now.

Added the new method Rset::isEmpty() - I am guessing that the migration work of Michael would have loved to have had this method

Added XRDSITE=cern_tape_archive_ci to eos sysconfig file in order to tell clients that there is a CTA backend

rdbms::Rset::next() now releases the underlying resources of a result set when there are no more rows to be fetched.

Added much needed comment to the setting of the CLIENT_FOUND_ROWS flag when making a MySQL database connection.

MysqlConn constructor now sets the CLIENT_FOUND_ROWS flag so that the reported number of rows affected by a DML statement matches that of Oracle, PostgreSQL and SQLite

Binary blobs containing zeros are now handled correctly.

Should be more efficient as it's a single copy operation instead of one
character at-a-time, but still requires 2 copies of the blob to convert
it from occi::Bytes to std::string (as it needs an intermediate char*
array).

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