The addition of '-p no:pytest_swh_core' in pytest.ini is needed to
prevent pytest from loading the pytest_swh_core plugin which we do not
need here and which would require some more dependencies (e.g.
requests).

Use the new SWHID naming convention instead of SWH PID.

pytest wastes a lot of time in .hypothesis and .git; this commit excludes them.

We may unknowingly pass naive datetimes to the storage through them,
causing the underlying DB to assign them a timezone that might not match
the actual one.

It already happens in swh.model and swh.loader.package tests.

Same as for the field data, it helps for code not yet migrated to use model
object.

Add missing object_type class attributes on MetadataAuthority, MetadataFetcher, and RawExtrinsicMetadata.

It can help in pytest's diffs

to fix a deprecationg warning.

 - Use dia directly to convert from .dia to .svg (inkscape would use dia via a
 plugin anyway)
 - Add proper runes to detect inkscape >= 1 and use the export options for that.

As NamedTuple inherits from tuple, msgpack serializes it like a tuple,
which makes it indistinguishable from a tuple when deserializing,
which is an issue for the RPC API.

It allows easy conversion of Union[ImmutableDict, Dict] to ImmutableDict.

So they are truly immutable now.

This will allow swh-storage to have a signature for *_metadata_add
that is consistent with other *_add endpoints.

Add a new extra_headers attribute on Revision and use it for computing
the revision's id instead of extract it from the metadata field.

Only accept (bytes, bytes) as extra_header.

Add a post init hook to Revision to initialize this new attribute from
given metadata, if any, for bw compat.

Also amend the revision_d hyptothesis strategy to generate extra_headers.
