https://perconadev.atlassian.net/browse/PS-10242 Added new template specializations for 'generic_post_header_impl' and 'generic_body_impl' for 'code_type::previous_gtids_log' ('PREVIOUS_GTIDS_LOG' event). 'binsrv::gtids::gtid_set' class is now capable of deserializing binary data from the blob encoded into the 'PREVIOUS_GTIDS_LOG' event. Introduced 'binsrv::gtids::gtid_set_storage' typedef - a vector-like container with 96 bytes SBO (based on 'boost::container::small_vector'). This type is used to store the blob mentioned above. The number 96 is chosen so that the size of the 'binsrv::event::event::body_variant' wouldnt grow. 'binsrv::gtids::gtid_set' interface extended with additional method 'add_interval()' for adding gno ranges. Fixed the way how 'binsrv::gtids::gtid_set' is printed to std::ostream - it now corresponds to the format used by '@@gtid_executed' MySQL system variable. Introduced new class 'binsrv::gtids::uuid' as a wrapper around 'boost::uuids::uuid' that can be constructed from 'binsrv::gtids::uuid_storage'. Unit tests updated to cover new methods in 'binsrv::gtids::gtid_set'. Added new 'test_uuid' unit test.
