This brings a simple config structure into the wallet3 that all of the
wallet submodules should be able to access. The first module included in
this PR is the daemon comms module which has its own substruct on the
config and the submodule is now constructed with a reference to the
config.
When building the pending transaction we can call GetFee() to calculate
how much the transaction will cost. It takes a single parameter for the
number of inputs because we will want to specify how many when
estimating.
We then build a list of the potential fees for up to 300 inputs and pass
that to our output selection function which will use it to determine if
the outputs selected will be sufficient to cover the fees. This allows
us to know in advance how much the fees will be rather than trial and
error.
tx scanning for basic transactions working
- TODO: subadresses. The scanning code is there, but it does not
currently know/care about any subaddresses.
daemon comms for basic syncing working
(multi-)wallet sync more or less working properly
- seem to have a dangling shared_ptr somewhere when removing a wallet from
daemon comms, so not working perfectly yet.
Lots of TODOs and cleanup needed, as well as further features of course.
