Also catch missing services for more complex searches
We did catch it on 'start()' which may not actually use a service that
was missing and only in a followup would the missing service be used.
So also catch the exception for missing service on the other event
handling methods.
This means that we now show a nice "setup needed" message to client when
a call is done that is not supported because of missing backing service.

Blockchain::Search: Clean a little and fix bugs
This follows the API docs on the utxoLookup() callback and we indeed
return back the blockheight/etc parameters even if the utxo is already
spent (represented by unspent=false).

Start project rest-service.
Transactions are only kept in the mempool a limited time before they are
removed and have to be re-entered by the owner of the transaction.
To keep mempools from being too different from the rest of the network we
can flush them based on the fact that if a tx hasn't been included yet in
this time, miners are not seeing it.
We reuse the NetworkManager lower level code in order to connect
to the Bitcoin P2P network.
This implements the basics for anyone wanting to be a player on
this network.
This is part of the protocol upgrade for 2020-05-15, and in general it
seems to go the direction of "we did this before, lets do this again".
The spec is clear enough, but there is still a lack of questioning and
testing. The problem this attempts to fix has been neutered for years[1].
The spec states:
> The essential idea of SigChecks is to perform counting solely in the
> spending transaction, and count actual executed signature check
> operations.
This, however nobel and logical, ignores that the
check-for-being-too-costly just pulled in a UTXO lookup and the loading
of the output script from the historical chain.
The goal that we protect against CPU over-use may be reached, but the
price is a total system slowdown. You can have multiple CPUs, but the
bus to permanent storage has one, max 2 parallel pipes.
To ensure theHub stays the number one scalable node, I didn't blindly
follow the spec, while making sure that the Hub is correctly going to
follow/reject consensus violations of newly mined blocks.
As a result the implementation in Flowee the Hub:
* does not check sigcheck-counts on historical blocks (more than 1000
blocks in the past).
This may increase the risk of chain-splits ever so slightly, but the cost
of disk-IO would be too high.
* No longer stores the value in the mempool, nor uses it for the
CPU-miner.
* Ties the sigcheck-limits to the user-set block-size-accept-limit.
This is contrary to the spec which mistakenly thinks that BCH has a
max block-size in the consensus rules. The effect is the same, though.
* The per-intput standardness suggestion is not implemented because
standardness checks don't currently fetch the previous outputs and
that would be too expensive to add.
* Standardness rules for the whole transaction are moved to the
mempool-acceptance logic instead. The cost would be too great
otherwise, similar to the previous point.
Again, the effect is the same as likely intented.
---
1) since the intro of the CachingTransactionSignatureChecker
Merkle-block and merkle-tree classes and methods are pretty much stand-
alone and can be moved with no efforts.
Also move the relevent unit test to qtestlib.
The API changes in boost between 1.66 and later was the need
for the boost_compat.h header file.
Its been a long time since Flowee started demanding 1.67 minimum
for boost, making this compat obsolete.
Using the forget() method too many times could lead to an invalid
(negative size) ConstBuffer being created.
This fixes and immediately copies an assert used in many other places in
the code already.
THe builder now allows you to create a message with the
serviceId, the messageId and the requestId pre-set.
This benefits code that just takes the output from the
builder and calls 'send' on it immediately saving several
lines of code.
Ship unit-testing functionality in the releease builds too,
external users may want to compile their apps in debug mode while
flowee is a release build.
This improves the double spend proof orphans code.
Also add a DSProof log-category and lots of log lines to make
looking at a debug build much more fun.
The recent introduction of helper methods on pubkey.h had the
side-effect of pulling in crypto libraries.
This splits the static methods into a separate namespace and file
to avoid such cross-module dependencies.
Move some files back to the server "library".
Merge the 'console' lib with server, as it doesn't really make sense with
just one file and nobody exclusively linking to it.
The server "libary" is not really a library, its the place we put all
the files shared by hub-qt hub-cli and hub.
We no longer depend on these files from other places (mostly due to
moving to the new logging framework) and as such we can move the files
back.
The API call for GetBlock has a filter-on-address functionality which is
now ported to no longer use ripe160 addresses but instead uses output-
script hashes.
This avoids problems for transactions not using p2pkh and generally is a
cleaner solution.
This also adds a unit test to test this feature.
Remove addresses of type ripe160 to be used in the API of AddresMonitor
API service. Instead use a sha256 hash of the entire output script.
This is mostly internal changes not affecting the operations much.
