* Partial blockchain.transaction.yyy RPC implementations.
* Register RPC service object.
* Move session manager start/stop to a better place.
* Attempt to fill in the details of transaction.get_batch,
including merkle path.
* Correct interpretation of DBStateValue Genesis hash.
* Convert Args.Port to int and validate. Run UDP ping server on JSONRPCPort too.
* Add BlockHeader to HeightHash notification.
* Limit session-based JSON RPC service to IPv4.
Client not ready for IPv6.
* Adapt to new HeightHash struct.
* Fine tune JSON RPC handlers and types to match lbry-sdk expectations.
Implement UnmarshalJSON()/MarshalJSON() for several types.
* Add more special handling of DBStateValue.Genesis hash.
* Set IncludeStop=false generally to avoid returning extra rows.
Other misc fixes.
* Make prefixes_test.go more resilient against garbage left
by a prior crash. Also correct error logging.
* Don't do the ones' complement thing with DBStateValue fields
HistFlushCount, CompFlushCount, CompCursor. Python-herald
doesn't do it, and it presents one more irregular case for
(un)marshalling fields.
* Simplify type-specific partial packing, and simplify dispatch for pack key/value.
* Add struct field annotations and refactor to prepare for
use of "restruct" generic packing/unpacking.
* Add dynamic pack/unpack based on "restruct" module.
Dispatch normal pack/unpack through tableRegistry[] map
instead of switch.
* Add 5 new prefixes/tables (TrendingNotifications..HashXMempoolStatus).
* Undo rename. TouchedOrDeleted -> ClaimDiff.
* Fixup callers of eliminated partial pack functions. Have them use key.PartialPack(n).
* Add pluggable SerializationAPI. Use it in prefixes_test.
Populate PrefixRowKV.RawKey,RawValue when appropriate.
* Undo accidental bump of rocksdb version.
* Add .vscode dir to gitignore.
* Fix ClaimToChannelValue annotation. Implement BlockTxsValue workaround
as I can't find the right annotation to get it marshalled/unmarshalled.
* Strengthen partial packing verification. Fix bugs
in UnpackKey/UnpackValue for new types.
* Remove .DS_Store, and ignore in future.
* Fix MempoolTxKey, TouchedHashXValue. Remove some unneeded struct tags.
* Generate test data and complete the tests for the new tables.
Add Fuzz tests for TouchedHashXKey, TouchedHashXValue with
happy path test data (only).
* Move tableRegistry to prefixes.go and rename it prefixRegistry.
Other minor fixes, comments.
* Add test that runs through GetPrefixes() contents, and verifies
they are registered in prefixRegistry.
