BOOST_TEST_MESSAGE() is not logged by default, and for some tests we
don't want to enable that because it's too noisy. But we need to know
the seed to reproduce a failure, so we better to always print it.
query::full_slice doesn't select any regular or static columns, which
is at odds with the expectations of its users. This patch replaces it
with the schema::full_slice() version.

"This changeset is the first step to flatten mutation_reader.
Then it introduces new mutation_fragment types for partition header and end of partition.
Using those a new flat_mutation_reader is defined.
Finally it introduces converters between new flat_mutation_reader and
old mutation_reader."
* 'haaawk/flattened_mutation_reader_v12' of github.com:scylladb/seastar-dev:
Add tests for flat_mutation_reader
Introduce conversion from flat_mutation_reader to mutation_reader
Introduce conversion from mutation_reader to flat_mutation_reader
Introduce flat_mutation_reader
Extract FlattenedConsumer concept using GCC6_CONCEPT
Introduce partition_end mutation_fragment
Introduce a position for end of partition
Introduce partition_start mutation_fragment
Introduce FragmentConsumer
Introduce a position for partition start
streamed_mutation: Extract concepts using GCC6_CONCEPT macro
Those tests run mutation source test for all sources
using conversion to and from flat_mutation_reader.

"When mutation reader enters the partition using index,
streamed_mutation object is returned to the user before the row start
fragment is processed. In that case, when we process the row start, we
should ignore it and not call setup_for_partition() again. That may
override user's fast_forward_to() request."
* 'tgrabiec/fix-initial-fast-forward-to-for-single-key-sstable-readers' of github.com:scylladb/seastar-dev:
tests: mutation_source_test: Test forwarding in single-key readers
sstables: Remove unused code
sstables: mutation_reader: Fix setup_for_partition() being called twice in some cases
sstables: Fix verify_end_state() to tolerate ATOM_START_2 state
The standard serialization API (e.g. in data_value) includes the following methods:
size_t serialized_size() const;
void serialize(bytes::iterator& it) const;
bytes serialize() const;
Align the utils::UUID API with the pattern above.
The only addition is that we are going to make an output iterator parameter of a second method above
a template so that we may serialize into different output sources.

This patch ensures we generate UUIDs using the same randomness source
as all the other values we randomly generator, so that we can get a
deterministic run from the seeds we print.

Tests using random mutation generator should be provided with bot
counter and non-counter mutations to ensure that both cases are
sufficiently covered. However, mixed schemas (with both counter and
non-counter columns) are not allowed so the RMG has to be explicitly
told whether to use counter or non-counter schema.
This reverts commit aa392810ff, reversing
changes made to a24ff47c637e6a5fd158099b8a65f1191fc2d023; it uses
boost::intrusive::detail directly, which it must not, and doesn't compile on
all boost versions as a consequence.
Wrapping ranges are a pain, so we are moving wrap handling to the edges.
Since cql can't generate wrapping ranges, this means thrift and the ring
maintenance code; also range->ring transformations need to merge the first
and last ranges.
