Allows loading the schema for the designated keyspace and table, from
the system table sstables located on disk. The sstable files opened for
read only.
This reverts commit 32fff17e19, reversing
changes made to 164afe14ad.
This series proved to be problematic, the new test introduced by it
failing quite often. Revert it until the problems are tracked down and
fixed.
Allows loading the schema for the designated keyspace and table, from
the system table sstables located on disk. The sstable files opened for
read only.
`load_one_schema()` and `load_schemas_from_file()` are dropped,
as they are neither used by `scylla-sstable` or tested by
`schema_loader_test.cc` . the latter tests `load_schemas()`, which
is quite the same as `load_one_schema_from_file()`, but is more
permissive in the sense that it allows zero schema or more than
one schema in the specified path.

Closes#13003
Schema related files are moved there. This excludes schema files that
also interact with mutations, because the mutation module depends on
the schema. Those files will have to go into a separate module.
Closes#12858
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 tool which can be used to examine the content of sstable(s) and
execute various operations on them. The currently supported operations
are:
* dump - dumps the content of the sstable(s), similar to sstabledump;
* index-dump - dumps the content of the sstable index(es), similar to
scylla-sstable-index;
* writetime-histogram - generates a histogram of all the timestamps in
the sstable(s);
* custom - a hackable operation for the expert user (until scripting
support is implemented);
* validate - validate the content of the sstable(s) with the mutation
fragment stream validator, same as scrub in validate mode;
A utility which can load a schema from a schema.cql file. The file has
to contain all the "dependencies" of the table: keyspace, UDTs, etc.
This will be used by the scylla-sstable-crawler in the next patch.
