This updates the coinbase transactions to reward service nodes
periodically rather than every block. If you recieve a service node
reward this reward will be delayed x blocks, if you receive another
reward to the same wallet before those blocks have been completed it
will be added to your total and all will be paid out after those x
blocks has passed.
For example if our batching interval is 2 blocks:
Block 1 - Address A receives reward of 10 oxen - added to batch
Block 2 - Address A receives reward of 10 oxen - added to batch
Block 3 - Address A is paid out 20 oxen.
Batching accumulates a small reward for all nodes every block
The batching of service node rewards allows us to drip feed rewards
to service nodes. Rather than accruing each service node 16.5 oxen every
time they are pulse block leader we now reward every node the 16.5 /
num_service_nodes every block and pay each wallet the full amount that
has been accrued after a period of time (Likely 3.5 days).
To spread each payment evenly we now pay the rewards based on the
address of the recipient. This modulus of their address determines which
block the address should be paid and by setting the interval to our
service_node_batching interval we can guarantee they will be paid out
regularly and evenly distribute the payments for all wallets over this
Converts all use of boost::filesystem to std::filesystem.
For macos and potentially other exotic systems where std::filesystem
isn't available, we use ghc::filesystem instead (which is a drop-in
replacement for std::filesystem, unlike boost::filesystem).
This also greatly changes how we handle filenames internally by holding
them in filesystem::path objects as soon as possible (using
fs::u8path()), rather than strings, which avoids a ton of issues around
unicode filenames. As a result this lets us drop the boost::locale
dependency on Windows along with a bunch of messy Windows ifdef code,
and avoids the need for doing gross boost locale codecvt calls.
When targetting macos <10.14 macos won't allow use of anything from
C++17 that throws, such as:
- std::get on a variant
- std::visit
- std::optional::value()
- std::any_cast
This avoids all of these.
For std::get, we either replace with std::get_if (where appropriate), or
else use a `var::get` implementation of std::get added to lokimq (also
updated here). (This `var` namespace is just an `std` alias everywhere
*except* old target macos).
For std::visit, likewise lokimq adds an var::visit implementation for
old macos that we use.
std::optional::value() uses weren't useful anyway as everywhere it calls
them we've already checked that the option has a value, in which case we
can use `*opt` (which doesn't check for contents and throw).
std::any just has to be avoided as far as I can tell, but the one place
we used it is only ever a block, so I just replaced it with a `const
block*`.
Because:
boost::join(v | boost::adaptors::transformed([](uint64_t out){return std::to_string(out);}), " ")
is ugly as sin, while:
tools::join(" ", v)
is nice and simple.
Also removes a few unnecessary boost iterator adaptor includes and uses.
A huge amount of this is repetitive:
- `boost::get<T>(variant)` becomes `std::get<T>(variant)`
- `boost::get<T>(variant_ptr)` becomes `std::get_if<T>(variant_ptr)`
- `variant.type() == typeid(T)` becomes `std::holds_alternative<T>(variant)`
There are also some simplifications to visitors using simpler stl
visitors, or (simpler still) generic lambdas as visitors.
Also adds boost serialization serializers for std::variant and
std::optional.
Removes all "using namespace epee;" and "using namespace std;" from the
code and fixes up the various crappy places where unnamespaced types
were being used.
Also removes the ENDL macro (which was defined to be `std::endl`)
because it is retarded, and because even using std::endl instead of a
plain "\n" is usually a mistake (`<< std::endl` is equivalent to `<<
"\n" << std::flush`, and that explicit flush is rarely desirable).

Incorrect assumption that a transaction can be kept in the chain if it could
eventually become invalid, because if it were the chain would be split and
eventually these transaction would be dropped. But also that we should not
override the pre-existing logic which handles this case anyway.
