This test case should have been based on CQL instead of creating
artificial update scenarios. It also contains invalid cases
regarding base and view row marker, so it's removed here
and replaced with CQL-based test in this same series.
The bulk materialized-view building processes (when adding a materialized
view to a table with existing data) currently reads the base table in
batches of 128 (view_builder::batch_size) rows. This is clearly better
than reading entire partitions (which may be huge), but still, 128 rows
may grow pretty large when we have rows with large strings or blobs,
and there is no real reason to buffer 128 rows when they are large.
Instead, when the rows we read so far exceed some size threshold (in this
patch, 1MB), we can operate on them immediately instead of waiting for
128.
As a side-effect, this patch also solves another bug: At worst case, all
the base rows of one batch may be written into one output view partition,
in one mutation. But there is a hard limit on the size of one mutation
(commitlog_segment_size_in_mb, by default 32MB), so we cannot allow the
batch size to exceed this limit. By not batching further after 1MB,
we avoid reaching this limit when individual rows do not reach it but
128 of them did.
Fixes#4213.
This patch also includes a unit test reproducing #4213, and demonstrating
that it is now solved.

Branch: next
Switch to the the CMake-ified Seastar
This change allows Scylla to be compiled against the `master` branch of
Seastar.
The necessary changes:
- Add `-Wno-error` to prevent a Seastar warning from terminating the
build
- The new Seastar build system generates the pkg-config files (for
example, `seastar.pc`) at configure time, so we don't need to invoke
Ninja to generate them
- The `-march` argument is no longer inherited from Seastar (correctly),
so it needs to be provided independently
- Define `SEASTAR_TESTING_MAIN` so that the definition of an entry
point is included for all unit test compilation units
- Independently link Scylla against Seastar's compiled copy of fmt in
its build directory
- All test files use the (now public) Seastar testing headers
- Add some missing Seastar headers to source files

Remove the timeout argument to
db::view::view_builder::wait_until_built(), a test-only function to
wait until a given materialized view has finished building.
This change is motivated by the fact that some tests running on slow
environments will timeout. Instead of incrementally increasing the
timeout, remove it completely since tests are already run under an
exterior timeout.

Right now materialized_views_test.cc contains view updating tests,
but the intention is to move mv-related tests from cql_query_test
here and use it for all future unit testing of MV.
sprint() recently became more strict, throwing on sprint("%s", 5). Replace
with the more modern format().
Mechanically converted with https://github.com/avikivity/unsprint.
This is a separate file from view_schema_test because that one is
already becoming too long to run; also, having multiple test files
means they can be executed in parallel.
