tuple: refactor flags Before this patch struct tuple had two boolean bit fields: is_dirty and has_uploaded_refs. It is worth mentioning that sizeof(boolean) is implementation depended. However, in code it is assumed to be 1 byte (there's static assertion restricting the whole struct tuple size by 10 bytes). So strictly speaking it may lead to the compilation error on some non-conventional system. Secondly, bit fields anyway consume at least one size of type (i.e. there's no space benefits in using two uint8_t bit fields - they anyway occupy 1 byte in total). There are several known pitfalls concerning bit fields: - Bit field's memory layout is implementation dependent; - sizeof() can't be applied to such members; - Complier may raise unexpected side effects (https://lwn.net/Articles/478657/). Finally, in our code base as a rule we use explicit masks: txn flags, vy stmt flags, sql flags, fiber flags. So, let's replace bit fields in struct tuple with single member called `flags` and several enum values corresponding to masks (to be more precise - bit positions in tuple flags).

datetime: fix set with hour=nil We did not retain correctly `hour` attribute if modified via `:set` method attributes `min`, `sec` or `nsec`. ``` tarantool> a = dt.parse '2022-05-05T00:00:00' tarantool> a:set{min = 0, sec = 0, nsec = 0} -- - 2022-05-05T12:00:00Z ... ``` Closes #7298 NO_DOC=bugfix

vinyl: rotate active memory index in vy_squash_process if necessary If vy_point_lookup called by vy_sauash_process yields (doing disk read), a dump may be triggered bumping the L0 generation counter, in which case we would insert a statement to a sealed vy_mem, as explained in #5080. Let's check the generation counter and rotate the active vy_mem if necessary after vy_point_lookup to avoid that. Closes #5080 NO_DOC=bug fix NO_TEST=complicated, need stress/perf test to catch bugs like this
