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.
