Eric Mastro b9e53e182f [marketplace] support freeing of slots and failed state
Support storage contract parameters to free slots after too many proofs missed, as well as fail a contract after too many slots have been freed.

Eric Mastro 372f827982 [marketplace] add/remove proofs for contract state
Add or remove proof requirements when a request contract’s state changes. When a request sale has completed (for a slot), the host who purchased that slot now must provide regular proofs for the data they are contracted to hold. This is now enforced by adding the slotId to the HashSet of Ids for which to require proofs. When a request has been cancelled (not all slots were filled before the request expired), proofs no longer need to be provided and the slotId is removed from teh HashSet.

Add `isCancelled` and `isSlotCancelled` checks to query the contract state without relying the on the state context variable in the contract. Because contract state can only be updated in a transaction, and the client withdrawing funds is responsible for changing the contract state to “Cancelled”, the `isCancelled` and `isSlotCancelled` functions were introduced to check the state regardless of whether or not the client had already withdrawn their funds.

Changes required for reasonable upload/download speed (#265)
Increase blocksize from ~8KiB to ~64KiB and remove useless unbounded prefetching on download
* increased upload/download speed on my Win10 Zen3 box to 50/150 MB/s (with FSStore)
* made manifest files 8x smaller
* two more changes in the tests to make them pass
Closes #263

Eric Mastro 6df5a7cf54 [chore] clean up `array[32, byte]` types
- rename `ContractId` to `SlotId`
- add `RequestId`, `PurchaseId`, `Nonce` types as aliases of `array[32, byte]`
- rename `Proving.contracts` to `Proving.slots`
- change signatures of `isSlotCancelled` and `isCancelled` to use `SlotId` and `RequestId` types, respectively.
- change all references to `RequestId`, `SlotId`, and `PurchaseId`

Download files without padding (#218)
The initial goal of this patch was to allow to download of a file via REST API in exactly the same size as it was uploaded, which required adding fields Chunker.offset and Manifest.originalBytes to keep that size. On top of that, we added more integrity checks to operations on Manifest, and reorganized TestNode.nim to test the actual interaction between node.store and node.retrieve operations.

Note that the wire format of Manifest was changed, so we need to recreate all BlockStores.

* Download without padding
* Fixed chunker tests
* Chunker: get rid of RabinChunker
* Verify offset in the chunker tests
* Use manifest.originalBytesPadded in StoreStream.size
* StoreStream: replace emptyBlock with zeroMem
* Manifest.bytes: compute how many bytes corresponding StoreStream(Manifest, pad) will return
* Manifest: verify originalBytes and originalLen on new/encode/decode
Also set originalBytes in each Manifest creation/update scenario
* Manifest: comments, split code into sections
* Reordered parameters to deal with int64 size in 32-bit builds
* TestNode.nim: combine Store and Retrieve tests
1. Instead of copy-pasting code from node.nim, new test calls node.store() and node.retrieve() in order to check that they can correctly store and then retrieve data
2. New test compares only file contents, manifest contents considered an implementation detail
3. New test chunks at odd chunkSize=BlockSize/1.618 in order to ensure that data retrieved correctly even when buffer sizes mismatch
* TestNode.nim: code refactoring
* Manifest.add: one more test
* Manifest.verify: return Result instead of raising Defect
* Node.store: added blockSize parameter

Michael Bradley, Jr 3d823dcbc6 [stores] update getBlock return type
change return type for `method getBlock` from `Future[?!(?Block)]` to
`Future[?!Block]`

use `type BlockNotFoundError = object of CodexError` to differentiate between
"block not found in the store" and other errors

also make some logic and error handling/messages more consistent across
BlockStore implementations

closes #177
closes #182
closes #210

alternative to #205, #209

WIP: Harmonize BlockStore API (remaining functions) (#123) (#130)
BlockStore API got new return types (rationale in https://github.com/status-im/nim-codex/issues/123#issuecomment-1163797753):
- getBlock: Future[?! (?Block)]
- putBlock/delBlock/listBlocks: Future[?!void]
- hasBlock: Future[?!bool]

Plus refactored readOnce(StoreStream) and check received data in its tests.

And replaced local use of AsyncHeapQueue with seq.sort.

Mark Spanbroek afdb5be2d4 Add TODOs to indicate wanted architecture
As discussed in team:
- Retrieving of blocks that are mentioned in the
  manifest should be moved into a BlockStore.
- Sales should be given an instance of BlockStore,
  and an instance of StorageProofs, instead of the
  onStore, onClear, and onProve callbacks
