In preparation to using LMDB as a wallet database, migrate the

transactions.

Adds a `BufWrite` around each file that gets incrementally written
to in the MMR store main types. Should speed up a few operations
quite a bit, but particularly flushing the remove log. Saving

block syncs a lot faster.

* updating grin/chain to include removelogs
* integration of flatfile structure, changes to chain/sumtree to start using them
* tests on chain, core and store passing
* cleaning up api and tests
* formatting
* flatfiles stored as part of PMMR backend instead
* all compiling and tests running
* documentation
* added remove + pruning to flatfiles
* remove unneeded enum
* adding sumtree root struct
* Util to zip and unzip directories
* First pass at sumtree request/response. Add message types, implement the exchange in the protocol, zip up the sumtree directory and stream the file over, with necessary adapter hooks.
* Implement the sumtree archive receive logicGets the sumtree archive data stream from the network and write it to a file. Unzip the file, place it at the right spot and reconstruct the sumtree data structure, rewinding where to the right spot.
* Sumtree hash structure validation
* Simplify sumtree backend buffering logic. The backend for a sumtree has to implement some in-memory buffering logic to provide a commit/rollback interface. The backend itself is an aggregate of 3 underlying storages (an append only file, a remove log and a skip list). The buffering was previously implemented both by the backend and some of the underlying storages. Now pushing back all buffering logic to the storages to keep the backend simpler.
* Add kernel append only store file to sumtrees. The chain sumtrees structure now also saves all kernels to a dedicated file. As that storage is implemented by the append only file wrapper, it's also rewind-aware.
* Full state validation. Checks that:
- MMRs are sane (hash and sum each node)
- Tree roots match the corresponding header
- Kernel signatures are valid
- Sum of all kernel excesses equals the sum of UTXO commitments
minus the supply
* Fast sync handoff to body sync. Once the fast-sync state is fully setup, get bacj in body sync
mode to get the full bodies of the last blocks we're missing.
* First fully working fast sync
* Facility in p2p conn to deal with attachments (raw binary after message).
* Re-introduced sumtree send and receive message handling using the above.
* Fixed test and finished updating all required db state after sumtree validation.
* Massaged a little bit the pipeline orphan check to still work after the new sumtrees have been setup.
* Various cleanup. Consolidated fast sync and full sync into a single function as they're very similar. Proper conditions to trigger a sumtree request and some checks on receiving it.
* Tried but failed to fix `cargo build` complaint about unused #[macro use]. See also 7a803a8dc1
* Compiler complaints be-gone
* Give sumtree tests method-tagged folder names so they don't overwrite each others' files
Fixes#658
Without a backup, the in-memory data structure stays truncated
even if the rewind is abandoned. Also add some logging on our
most problematic block in case it still is problematic.
Fixes buffer misalignment when reading back pruning data.
Everything after the buffer length (8000 bytes) was badly read on
restart, leading to accepting double spends.
The MMR storage has a buffer for all changes so they can either
be discarded without side effects or committed to disk. Pruning
can also happen in the buffer if an input directly spends an
output in a block (not likely), or a fork has an input spending
a previous output within it.
When the buffer gets flushed to storage, the pruned element was
just skipped, causing an offset within the underlying storage and
a shorter file than expected. This fix writes zeroes instead, so
the size is consistent. Note that the zeroes will be removed with
all other pruned elements on next compaction.
Fixes#444
Only the temporary remove log for the last block was written to
disk, and then overwritten for every block. The fix writes the
temp remove log (just last block) to the permanent remove log,
and saves that to disk.
