This is the implementation of EIP-8070 Sparse Blobpool. It introduces protocol version eth/72 which relays blob transaction cells instead of full blobs. The blobpool now store 'incomplete' transactions, where only some of the cells are provided. The stored cell indexes are taken from the custody bitmap, which is provided by the consensus layer in forkchoiceUpdatedV4. This method will be called once Glamsterdam activates, and the default custody is full custody, so for now there is no change in the amount of stored cells for now. The main entities added are the BlobBuffer and BlobFetcher, which work together to track and fetch missing cells from connected peers. The partial transactions become available for inclusion in blocks when they are covered by enough peers that hold all cells. This change also introduces engine_getBlobsV4, which allows for cell-based responses (and partial blobs with only some of the cells). We maintain backward compatibility with getBlobsV3 which expects full blob responses by recovering the blob from available cells. Since this process is resource-intensive, we proactively cache the conversion so it is ready in time for getBlobsV3 calls. This mechanism will be removed once support for getBlobsV4 is universal across all consensus layer implementations. devp2p tests for eth/72 are not part of this initial change. This is to avoid breaking test success status for execution clients that do not have eth/72 implemented yet. The tests will be added in a subsequent change. --------- Co-authored-by: Felix Lange <fjl@twurst.com>
