Implement compression of objects before they are saved into the storage
provider. Each container type can specify which algorithm to use
(currently `none` or `zstd`) and the compression level.
Change byte containers from being just a `using` of the relative class
(e.g. `BytesContainer`) to a full fledged subclass. This has the
following benefits:
* The template arguments are now laid out in the container class body,
making it more readable.
* The creation of a new class creates a new symbol, improving
debuggability as now the container classes have their own name rather
than the expanded base class template.
Make the interface required by `SingleOutputPipe` similar to other
piperuns by requiring a constructor, the use of `PipeRunArgument`s and
the implementation of a non-static `run` function.
After this commit, every non-key field is treated as if it was optional
while every key field (plus every auto-generated `Kind` field) - as if
it was required.
Here we start restructuring the the schemas YAML such that it
contains a top-level `version` field. In this commit we only modify
the YAML, the build system changes will come later, to avoid
enormous commits.
In this commit we instruct the build system to use the unified schema
files instead of collecting the `TUPLE-TREE-YAML` comments.
The fixes to C++ files are necessary because they depend on the order
of the fields in the schema, which was changed.
These schema files are currently generated at build time by
collecting various TUPLE-TREE-YAML comments using the
`extract_yaml.py` script. In this commit we move them to the codebase
but we don't use them yet, this will be done at a later commit for
the sake of readability.
Because of how name builders used to lazy gather namespaces on the first
requested name, the objects were self mutating. As such only non-const
references could be used to pass them around.
Since that is no longer the case, this restores most of lost const
qualifiers.
