4670ba90e5 scripts: remove git-archive-all
since we don't build the rpm/deb packages from source tarball anymore,
instead we build the rpm/deb packages from precompiled relocatable
package. there is no need to keep git-archive-all in the repo. in this
change, the git-archive-all script and its license file are removed.
they were added for building rpm packages from source tarball in
f87add31a7.

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

383a9c6da9 Add abseil as a submodule
This adds the https://abseil.io library as a submodule. The patch
series that follows needs a hash table that supports heterogeneous
lookup, and abseil has a really good hash table that supports that
(https://abseil.io/blog/20180927-swisstables).

The library is still not available in Fedora, but it is fairly easy to
use it directly from a submodule.

f14e6e73bb Add ZStandard compression
This adds the option to compress sstables using the Zstandard algorithm
(https://facebook.github.io/zstd/).
To use, pass 'sstable_compression': 'org.apache.cassandra.io.compress.ZstdCompressor'
to the 'compression' argument when creating a table.
You can also specify a 'compression_level'. See Zstd documentation for the available
compression levels.
Resolves #2613.

102cf40bb7 Add xxhash (fast non-cryptographic hash) as submodule
Signed-off-by: Duarte Nunes <duarte@scylladb.com>

Note:
  xxhash repo should be cloned to Scylla organization, and that
  git url should be used instead.

77cb2b452f Merge "CQL 3.3.1 support" from Pekka
"This patch series adds support for CQL 3.3.1. The changes to CQL are listed
here:

  https://github.com/apache/cassandra/blob/cassandra-2.2/doc/cql3/CQL.textile#changes

The following CQL features are already supported by Scylla:

  - TRUNCATE TABLE alias
  - Double-dollar string literals
  - Aggregate functions: MIN, MAX, SUM, and AVG

This series adds the following CQL features:

  - New data types: tinyint, smallint, date, and time
  - CQL binary protocol v4 (required by the new data types)
  - Advertise Cassandra 2.2.8 version from Scylla so that drivers correctly
    detect the presence of CQL 3.3.1

The following CQL features are not supported by Scylla:

  - Role-based access control (issue #1941)
  - JSON data type
  - User-defined functions (UDFs)
  - User-defined aggregates (UDAs)

The following CQL binary protocol v4 changes are not implemented by this
series:

  - Read_failure and Write_failure error codes are not implemented.
    They error codes not used by the smart drivers but as they are
    propagated to application code, we eventually need to wire them up
    to our storage proxy implementation.
  - Function_failure error code is only used by user-defined functions
    and the fromJson function, which are not implemented by Scylla.

Fixes #1284."

041b0a65ac Implement intrusive set using rbtree_algorithms
This new implementation takes less memory because it
does not store comparator.

It also uses tree nodes optimized for size. This means
that instead of storing an enum field |color| they embed
this information inside pointer to parent.

1d9ee358f1 Revert "Merge "Reduce the size of mutation_partition" from Piotr"
This reverts commit aa392810ff, reversing
changes made to a24ff47c637e6a5fd158099b8a65f1191fc2d023; it uses
boost::intrusive::detail directly, which it must not, and doesn't compile on
all boost versions as a consequence.

cc17c44640 Move seastar to a submodule

subdirectory (as a submodule) and use seastar.pc/libseastar.a to link
with it.
