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.
Closes#9937
A trichotomic comparator returning an int an easily be mistaken
for a less comparator as the return types are convertible.
Use the new std::strong_ordering instead.
A caller in cql3's update_parameters.hh is also converted, following
the path of least resistance.
Ref #1449.
Test: unit (dev)
Closes#8323
The keys classes (partition_key et al) already use managed_bytes,
but they assume the data is not fragmented and make liberal use
of that by casting to bytes_view. The view classes use bytes_view.
Change that to managed_bytes_view, and adjust return values
to managed_bytes/managed_bytes_view.
The callers are adjusted. In some places linearization (to_bytes())
is needed, but this isn't too bad as keys are always <= 64k and thus
will not be fragmented when out of LSA. We can remove this
linearization later.
The serialize_value() template is called from a long chain, and
can be reached with either bytes_view or managed_bytes_view.
Rather than trace and adjust all the callers, we patch it now
with constexpr if.
operator bytes_view (in keys) is converted to operator
managed_bytes_view, allowing callers to defer or avoid
linearization.
Currently, we cannot select more than 2^32 rows from a table because we are limited by types of
variables containing the numbers of rows. This patch changes these types and sets new limits.
The new limits take effect while selecting all rows from a table - custom limits of rows in a result
stay the same (2^32-1).
In classes which are being serialized and used in messaging, in order to be able to process queries
originating from older nodes, the top 32 bits of new integers are optional and stay at the end
of the class - if they're absent we assume they equal 0.
The backward compatibility was tested by querying an older node for a paged selection, using the
received paging_state with the same select statement on an upgraded node, and comparing the returned
rows with the result generated for the same query by the older node, additionally checking if the
paging_state returned by the upgraded node contained new fields with correct values. Also verified
if the older node simply ignores the top 32 bits of the remaining rows number when handling a query
with a paging_state originating from an upgraded node by generating and sending such a query to
an older node and checking the paging_state in the reply(using python driver).
Fixes#5101.
and replace all dht::global_partitioner().decorate_key
with dht::decorate_key
It is an improvement because dht::decorate_key takes schema
and uses it to obtain partitioner instead of using global
partitioner as it was before.

1. Move tests to test (using singular seems to be a convention
in the rest of the code base)
2. Move boost tests to test/boost, other
(non-boost) unit tests to test/unit, tests which are
expected to be run manually to test/manual.
Update configure.py and test.py with new paths to tests.
