assert() is traditionally disabled in release builds, but not in
scylladb. This hasn't caused problems so far, but the latest abseil
release includes a commit [1] that causes a 1000 insn/op regression when
NDEBUG is not defined.
Clearly, we must move towards a build system where NDEBUG is defined in
release builds. But we can't just define it blindly without vetting
all the assert() calls, as some were written with the expectation that
they are enabled in release mode.
To solve the conundrum, change all assert() calls to a new SCYLLA_ASSERT()
macro in utils/assert.hh. This macro is always defined and is not conditional
on NDEBUG, so we can later (after vetting Seastar) enable NDEBUG in release
mode.

thrift support was deprecated since ScyllaDB 5.2
> Thrift API - legacy ScyllaDB (and Apache Cassandra) API is
> deprecated and will be removed in followup release. Thrift has
> been disabled by default.
so let's drop it. in this change,
* thrift protocol support is dropped
* all references to thrift support in document are dropped
* the "thrift_version" column in system.local table is
preserved for backward compatibility, as we could load
from an existing system.local table which still contains
this clolumn, so we need to write this column as well.
* "/storage_service/rpc_server" is only preserved for
backward compatibility with java-based nodetool.
* `rpc_port` and `start_rpc` options are preserved, but
they are marked as "Unused". so that the new release
of scylladb can consume existing scylla.yaml configurations
which might contain these settings. by making them
deprecated, user will be able get warned, and update
their configurations before we actually remove them
in the next major release.

get0() dates back from the days where Seastar futures carried tuples, and
get0() was a way to get the first (and usually only) element. Now
it's a distraction, and Seastar is likely to deprecate and remove it.
Replace with seastar::future::get(), which does the same thing.
Split long running test_aggregate_functions to one case per type.
This allows test.py to run them in parallel.
Before this it would take 18 minutes to run in debug mode. Afterwards
each case takes 30-45 seconds.

The expression system uses managed_bytes_opt for values, but result_set
uses bytes_opt. This means that processing values from the result set
in expressions requires a copy.
Out of the two, managed_bytes_opt is the better choice, since it prevents
large contiguous allocations for large blobs. So we switch result_set
to use managed_bytes_opt. Users of the result_set API are adjusted.
The db::function interface is not modified to limit churn; instead we
convert the types on entry and exit. This will be adjusted in a following
patch.
these warnings are found by Clang-17 after removing
`-Wno-unused-lambda-capture` and '-Wno-unused-variable' from
the list of disabled warnings in `configure.py`.

Schema related files are moved there. This excludes schema files that
also interact with mutations, because the mutation module depends on
the schema. Those files will have to go into a separate module.
Closes#12858
We have enabled the command line options without changing a
single line of code, we only had to replace old include
with scylla_test_case.hh.
Next step is to add x-log-compaction-groups options, which will
determine the number of compaction groups to be used by all
instantiations of replica::table.

In order to propagate exceptions as values through the CQL layer with
minimal modifications to the interfaces, a new result_message type is
introduced: result_message::exception. Similarly to
result_message::bounce_to_shard, this is an internal type which is
supposed to be handled before being returned to the client.
Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.

This is another boring patch.
One of schema constructors has been deprecated for many years now but
was used in several places anyway. Usage of this constructor could
lead to data corruption when using MX sstables because this constructor
does not set schema version. MX reading/writing code depends on schema
version.
This patch replaces all the places the deprecated constructor is used
with schema_builder equivalent. The schema_builder sets the schema
version correctly.

The min/max aggregators use aggregate_type_for comparators, and the
aggregate_type_for<timeuuid> is regular uuid. But that yields wrong
results; timeuuids should be compared as timestamps.
Fix it by changing aggregate_type_for<timeuuid> from uuid to timeuuid,
so aggregators can distinguish betwen the two. Then specialize the
aggregation utilities for timeuuid.
Add a cql-pytest and change some unit tests, which relied on naive
uuid comparators.

This detaches *like_operator*, *group_by*, *functions*
and *large* cases into own files. The split is not
uniform -- the resulting 4 tests run less that 3 minutes
each, what's left in the origin runs ~11 minutes. But
since the goal was to get out of 14 minutes threshold
and this file contains 126 cases (the champion) so I
just did "wildcard" selection that worked.
It also required moving require_rows() helpers into a
local header.
