Transactions can have token information before the output-script,
as such we add the filter and only go for the data we actually want.
This code is written by Telegram user @John_Galts_Gulch.
If for some reason there are a massive amount of orphaned headers, we
don't just keep them around until they are resolved as that is
detrimental to the operation of the node.
Special case this for a reindex and simply skip all orphans fur the
duration.
As we moved most of the creation of a BufferPool to be via the
Streaming::pool() method, which uses a thread-local, it makes sense
to start cleaning up the design and make it more modern C++.
The above mentioned method would return a reference and you'd see
loads of places use `auto &pool =` which is less than ideal.
As the number of places where we actually instantiate a BufferPool
goes down, the usage of some sort of smart pointer makes more sense.
This now makes all APIs use BufferPool be wrapped in a shared_ptr.
Version.h held mostly stuff for protocol.h, which is a hub-specific file.
The only thing that we actually use is the PROTOCOL_VERSION in our code
and as such that one moved to the interfaces dir.
These are technically static libs, but not in any way shared libs.
They are used solely only by this repo and really only by the hub.
Most important, no header files are installed and basically none of
the normal rules for reusable libraries are applied to these files.
