fcb8d040e8 treewide: use Software Package Data Exchange (SPDX) license identifiers
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

d768e9fac5 cql3, related: switch to data_dictionary
Stop using database (and including database.hh) for schema related
purposes and use data_dictionary instead.

data_dictionary::database::real_database() is called from several
places, for these reasons:

 - calling yet-to-be-converted code
 - callers with a legitimate need to access data (e.g. system_keyspace)
   but with the ::database accessor removed from query_processor.
   We'll need to find another way to supply system_keyspace with
   data access.
 - to gain access to the wasm engine for testing whether used
   defined functions compile. We'll have to find another way to
   do this as well.

The change is a straightforward replacement. One case in
modification_statement had to change a capture, but everything else
was just a search-and-replace.

Some files that lost "database.hh" gained "mutation.hh", which they
previously had access to through "database.hh".

also convert relation::to_term().

cf10df10f4 cql3: token_relation: convert term::raw to expressions
Change term::raw in token_relation to expressions.

to_term() is not converted, since it's part of the larger relation
hierarchy.

49ddd269ea cql3: rename variable_specifications to prepare_context
The class is repurposed to be more generic and also be able
to hold additional metadata related to function calls within
a CQL statement. Rename all methods appropriately.

Visitor functions in AST nodes (`collect_marker_specification`)
are also renamed to a more generic `fill_prepare_context`.

The name `prepare_context` designates that this metadata
structure is a byproduct of `stmt::raw::prepare()` call and
is needed only for "prepare" step of query execution.

d97605f4f8 cql3: Drop operator_type from the parser
Replace operator_type with the nicer-behaved oper_t in CQL parser and,
consequently, in the relation hierarchy and column_condition.

After this, no references to operator_type remain in live code.

f6e765b70f cql3: pass column_specification via lw_shared_ptr
`column_specification` class is marked as "final": it's safe
to use non-polymorphic pointer "lw_shared_ptr" instead of a
more generic "shared_ptr".

8efb02146f cql3: const cleanups and API de-pointerization
* Pass raw::select_statement::parameters as lw_shared_ptr
 * Some more const cleanups here and there
 * lists,maps,sets::equals now accept const-ref to *_type_impl
   instead of shared_ptr
 * Remove unused `get_column_for_condition` from modification_statement.hh
 * More methods now accept const-refs instead of shared_ptr

Every call site where a shared_ptr was required as an argument
has been inspected to be sure that no dangling references are
possible.

a46f235092 cql3: prefer passing schema as const ref instead of shared_ptr
De-pointerize cql3 code APIs further: change some call sites
to pass `schema` as const-ref instead of `shared_ptr`.

Affected functions known to be expecting always non-null
pointer to schema and don't store or pass the pointer somewhere
else, assuming it's safe to give them just a reference.

e1b22b6a4c cql3: get rid of lw_shared_ptr for variable_specifications
`parsed_statement::get_bound_variables` is assumed to always
return a nonnull pointer to `variable_specifications` instance.

In this case using a pointer is superfluous and can be safely
replaced by a plain reference.

Also add a default ctor and a utility method `set_bound_variables`
to the `variable_specifications` class to actually reset the
contents of the class instance.

aba9a11ff0 cql: pass variable_specifications via lw_shared_ptr
Instances of `variable_specifications` are passed around as
shared_ptr's, which are redundant in this case since the class
is marked as `final`. Use `lw_shared_ptr` instead since we know
for sure it's not a polymorphic pointer.

21d7722594 cql3: Add LIKE relation
Add a new type of relation with operator LIKE.  Handle it in
relation::to_restriction by introducing a new virtual method for it.
The temporary implementation of this method returns null; that will be
replaced in a subsequent patch.

Add abstract_type::is_string() to recognize string columns and
disallow LIKE operator on non-string columns.
