2023-10-10 r/6777 fix(tvix/castore): handle Directory::size overflow explicitlyedef2-9/+90
We use checked arithmetic for computing the total size, and verify that size is in-bounds in Directory::validate. If an out-of-bounds size makes it to the "unchecked" size method, we either panic (in debug mode), or silently saturate to u32::MAX. No new panic sites are added, since overflows in debug mode already panic at the language level.

2023-10-10 r/6773 chore(tvix/nar-bridge): move to Export from storev1pbFlorian Klink8-335/+49
This removes the Export method in nar-bridge, and updates all users to the version now in storev1pb. It moves the roundtrip test to the importer crate, and some of the utility functions into a separate util_test.go file.

2023-10-10 r/6772 feat(tvix/store/protos): add ExportFlorian Klink10-79/+387
Export will traverse a given PathInfo structure, and write the contents in NAR format to the passed Writer. It uses directoryLookupFn and blobLookupFn to resolve references. This is being moved over from nar-bridge. We need to keep the code there around until we can bump go.mod to storev1 with this merged, but the tests can already be moved entirely.

Consistent error messages, and slightly nicer code layout. We avoid printing the input data, since we primarily want to point out the specific violated invariant. In the one place where we do want to, we use BStr's Debug implementation, since byte slices don't print nicely.

Without the examples, some behaviour of the merge operator might not be clear from the previous description. Due to how pervasively the operator is used, I think it warrants a separate section.
