Prepared LIST statements were not calculating metadata in PREPARE path, and sent empty string hash to client causing problematic behaviour where metadat_id was not recalculated correctly.
This patch moves metadata construction into get_result_metadata() for the affected LIST statements and reuse that metadata when building the result set.
This gives PREPARE a stable metadata id for LIST ROLES, LIST USERS, LIST PERMISSIONS and the service-level variants.
This patch also adds a new boost test that verifies that when an EXECUTE request carries an empty result metadata id while the server has a real metadata id for the result set, the response is marked METADATA_CHANGED and includes the full result metadata plus the server metadata id.
This covers the recovery path for clients that send an empty or otherwise unusable metadata id instead of a matching cached one.
they are part of the CQL type system, and are "closer" to types.
let's move them into "types" directory.
the building systems are updated accordingly.
the source files referencing `types.hh` were updated using following
command:
```
find . -name "*.{cc,hh}" -exec sed -i 's/\"types.hh\"/\"types\/types.hh\"/' {} +
```
the source files under sstables include "types.hh", which is
indeed the one located under "sstables", so include "sstables/types.hh"
instea, so it's more explicit.

Closes#12926
After fcb8d040 ("treewide: use Software Package Data Exchange
(SPDX) license identifiers"), many dual-licensed files were
left with empty comments on top. Remove them to avoid visual
noise.
Closes#10562
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
This moves sstring copies from the callers to the constructor
implementation.
While at it, move the implementation out-of-line.

There's no benefit to using C include guards so switch to pragma once
everywhere for consistency.

Also replace derived types (map_type, collection_type, etc.).
As we'll change data_type's definition, this reduces the number of places
that need to be modified later, and is more readable.
In Origin, some places in CQL3 package treat ColumnDefinition as
ColumnSpecification. Origin solves that by making ColumnDefinition
extend ColumnSpecification.
I find it much simpler to provide an external adapter, which is cached
as a field for efficiency. Another, more important, reason for this
solution is that column_specifications are passed around as
shared_ptrs and I don't want to add unnecessary indirection to
column_definition accesses just because of that, to make it inherit
from column_specification.
