sprint() recently became more strict, throwing on sprint("%s", 5). Replace

After the new in-memory representation of cells was introduced there was
a regression in atomic_cell_or_collection::operator<< which stopped
printing the content of the cell. This makes debugging more incovenient
are time-consuming. This patch fixes the problem. Schema is propagated
to the atomic_cell_or_collection printer and the full content of the
cell is printed.
Fixes#3571.

Readers for SST3 return a bit more precise range tombstones
when reader is slicing. Namely, SST2 readers return whole
range tombstones that overlap with slicing range but SST3
trim those range tombstones to slicing range.

Currently timeout is opt-in, that is, all methods that even have it
default it to `db::no_timeout`. This means that ensuring timeout is used
where it should be is completely up to the author and the reviewrs of
the code. As humans are notoriously prone to mistakes this has resulted
in a very inconsistent usage of timeout, many clients of
`flat_mutation_reader` passing the timeout only to some members and only
on certain call sites. This is small wonder considering that some core
operations like `operator()()` only recently received a timeout
parameter and others like `peek()` didn't even have one until this
patch. Both of these methods call `fill_buffer()` which potentially
talks to the lower layers and is supposed to propagate the timeout.
All this makes the `flat_mutation_reader`'s timeout effectively useless.
To make order in this chaos make the timeout parameter a mandatory one
on all `flat_mutation_reader` methods that need it. This ensures that
humans now get a reminder from the compiler when they forget to pass the
timeout. Clients can still opt-out from passing a timeout by passing
`db::no_timeout` (the previous default value) but this will be now
explicit and developers should think before typing it.
There were suprisingly few core call sites to fix up. Where a timeout
was available nearby I propagated it to be able to pass it to the
reader, where I couldn't I passed `db::no_timeout`. Authors of the
latter kind of code (view, streaming and repair are some of the notable
examples) should maybe consider propagating down a timeout if needed.
In the test code (the wast majority of the changes) I just used
`db::no_timeout` everywhere.

test_streamed_mutation_forwarding_is_consistent_with_slicing already has
a REQUIRE() for the mutation read with the slicing reader. Add another
one for the forwarding reader. This makes it more consistent and also
helps finding problems with either the forwarding or slicing reader.
Caused assert failure when collection cells were so large as to
require fragmentation. Currently collection cells are not fragmented,
and deserialization asserts that.

that's required after fa5a26f12d on because sstable write fails when sharding
metadata is empty due to lack of keys that belong to current shard.
make_local_key* were moved to header to avoid compiling sstable_utils.cc into
all those tests that rely on simple_schema.hh, which is a lot.

BOOST_TEST_MESSAGE() is not logged by default, and for some tests we

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."
