Use generic types instead of trait objects in tx pool (#3308)
Tx pool takes some parameters as trait objects. It's not an idiomatic Rust code, in this particular case we should use generic types. Trait object makes sense when we accept in runtime different concrete types which implement the trait as a value of the same field. It's not the case here. Trait objects come with a price - instead of method dispatch in compile time we have to accept runtime dispatch. My guess we did it to not clutter the code with type parameters, which is understandable but still suboptimal.

Always stem local txs if configured that way (unless explicitly fluffed) (#2876)
* always stem local txs if configured that way (unless explicitly fluff from wallet)
this overrides current epoch behavior for txs coming in via "push-api"
rename "local" to "our" txs

* TxSource is now an enum for type safety.

5d904250d5 Use failure for Pool and Committed errors (#2570)

Rework "bucket transactions" logic (buckets are now weight limited) (#2487)
* rework bucket txs

* introduce max_block_weight to global (based on chain_type)
not yet in use anywhere...

* now using global::max_block_weight() everywhere

* testing max_block_weight needs to be big enough to cover existing chain tests...

* add some test coverage for prepare mineable transactions at the block weight limit
introduce AsLimitedTx{max_weight} so we can build artifically small blocks (per mining config)

* cleanup

* default_mineable_max_weight is just the default max_block_weight
we do not need to account for coinbase reward here (tx vs block)

* 75 change outputs in a test is not valid now that we have a low block weight limit...
