Spans are more flexible and can be constructed from any contiguous
container (such as small_vector), or a subrange of such a container.
This can save allocations, so change the signature to accept a span.
Spans cannot be constructed from std::initializer_list, so one such
call site is changed to use construct a span directly from the single
argument.
Now that we don't accept cql protocol version 1 or 2, we can
drop cql_serialization format everywhere, except when in the IDL
(since it's part of the inter-node protocol).
A few functions had duplicate versions, one with and one without
a cql_serialization_format parameter. They are deduplicated.
Care is taken that `partition_slice`, which communicates
the cql_serialization_format across nodes, still presents
a valid cql_serialization_format to other nodes when
transmitting itself and rejects protocol 1 and 2 serialization\
format when receiving. The IDL is unchanged.
One test checking the 16-bit serialization format is removed.
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
Eliminate not used includes and replace some more includes
with forward declarations where appropriate.

As reproduced in cql-pytest/test_json.py and reported in issue #7911,
failing fromJson() calls should return a FUNCTION_FAILURE error, but
currently produce a generic SERVER_ERROR, which can lead the client
to think the server experienced some unknown internal error and the
query can be retried on another server.
This patch adds a new cassandra_exception subclass that we were missing -
function_execution_exception - properly formats this error message (as
described in the CQL protocol documentation), and uses this exception
in two cases:
1. Parse errors in fromJson()'s parameters are converted into a
function_execution_exception.
2. Any exceptions during the execute() of a native_scalar_function_for
function is converted into a function_execution_exception.
In particular, fromJson() uses a native_scalar_function_for.
Note, however, that functions which already took care to produce
a specific Cassandra error, this error is passed through and not
converted to a function_execution_exception. An example is
the blobAsText() which can return an invalid_request error, so
it is left as such and not converted. This also happens in Cassandra.
All relevant tests in cql-pytest/test_json.py now pass, and are
no longer marked xfail. This patch also includes a few more improvements
to test_json.py.
Fixes#7911

Every native scalar function is already tagged whether they're pure or
not but because we don't implement the is_pure() function, all functions
end up being advertised as pure. This means that functions like now()
that are *not* pure, end up being evaluated only once.
Fixes#571.

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.
Change function argument types and return values to bytes_opt.
Note: a comment in the code says that NULL arguments are not supported,
but it seems prudent to prepare for the day they will be.
The Functions class wants to store functions in a map and hand them out later,
so we need a shared_ptr.
(could have had a map of name -> function factory, maybe one day)
