and avoid applying header to header PMMR before validation
as this potentially leaves the PMMR in a tricky state to rewind from

We have a method get which returns a Vec, it's used in cases when we can't implement FromLmdbBytes or Readable on a desired type, eg when both traits and type are external for the current crate. This approach requires an extra allocation of a Vec, this PR introduces a method which accepts desirialzer as closure, which allows to desrialize in place without an intermidiate heap allocation.
It's still possible to get a Vec if needed, just pass a Vec constructor to get_with.
We have to make an extra allocation per db get request because key generation function to_key takes Vec. Taking byte slice (AsRef<[u8]> to be precise) also simplifes the code a bit.
Currently Writable accepts trait Write as a type parameter but Readable
takes Read as a trait object, which is not symmetrical and also less performant. This PR changes Readable trait and all places where it's used
* Refactor SyncState
Method sync_error() retrun type was simplified.
update_txhashset_download() was made type safe, which eliminates a runtime enum variant's check, added an atomic status update
* Node API: don't error on missing output
* Propagate errors from get_output*
* Rename is_unspent and small refactor
* Forgot to rename function in tests
* Change Batch get_output_pos_height type signature
* no need to rehash with index to compare output with input spending it
* compare output identifier when checking is_unspent()
* output identifier from cleanup
* first pass at rewind_single_block
and reworking rewind to simply iterate over blocks, rewinding each incrementally
* commit
* commit
* cleanup
* add test coverage for output_pos index transactional semantics during rewind
* commit
* do not store commitments in spent_index
just use the order of the inputs in the block
* compare key with commitment when cleaning output_pos index
* remove unused OutputPos struct
* no need for AsFixedBytes we can just use AsRef<[u8]>
* cleanup FixedLength trait
* revert this change for now
* fix store tests
* cleanup and fix tests after rebase
* fix tests
* update based on PR review
less hard-coded values now
* cleanup
* Refactor to pass batch around explicitly rather than keeping it in the extension.
We would like to be able to pass an extension around and potentially clone it.
* cleanup, pass header around where it makes sense
* Node API v2
* Update gitignore
* Add get_pmmr_indices method
* Add Foreign and Owner API each one with specific secret
* Fix failing tests
* Revert to 'Option<u64>'
* add bitmap accumulator
refactor vec backend so we can use it outside of tests
introduce a "hash only" vec backend for the accumulator
* get core tests passing
* initial test coverage for bitmap_accumulator
* better test coverage for bitmap accumulator and cleanup code
* refactor txhashset roots, call validate() on roots during block validation
* fix store tests
* log the "merged" root when validating roots
* cleanup, revise based on feedback
* cleanup
* rework it to pass explicit size into bitmap accumulator when applying
* fix: split state validation status into kernel and rproof updates. And fix sync status for these two states
* fix: show correct number of leaves for pruned MMR as well as unpruned
* docs: better docs for kernel/range proof validation
* fix: ordering of kernel and rproofs validation in TUI
* fix: typo in rangeproofs api and comments
* add function to retrieve a set of pmmr indices between a given block height range
* typo
* change APU to just return required indices
* change pmmr index retrieval, change new function to only return pmmr indices between blocks
* Verify headers and blocks only when needed
Curretnly we have some lightweigt validation implemented as part of
entity deserialization, which is safer and allows us to not parse the
entire object if some part is invalid. At the same time this logic
always applies when we read an entity, eg when reading from DB.
This PR introduces UntrustedHeader/Block which is used when we read from
the network. It does partial validation during read, then it is supposed
to be converted into regular header/block which doesn't validate itself.
Also this PR adds "lightweight" validation to block header read like we have
for block body, so we don't parse block body if the header is invalid.
Fixes#1642
* Move version validation to untrusted header
* update fuzz tests
