* fix some warnings related to beacon_node splitting; reimplement finalization verification more robustly; improve attestation pool block selection logic
* re-add missing import
* whitelist allowed state transition flags and make rollback/restore naming more consistent
* restore usage of update flags passed into skipAndUpdateState(...) in addition to the potential verifyFinalization flag
* switch rest of rollback -> restore
* remove incorrect/obsolete comment; deprecate BeaconState state transition functions
* remove deprecated state_transition(state: var BeaconState)
* add specific workarounds for state_transition() and process_slots() to nfuzz_block() and addTestBlock()
* Jenkins: add timeouts to testnet finalisation tests
- add nicer child process management to "launch_local_testnet.sh"
- correct a comment in "start.sh"
* the Jenkins worker's version of "timeout" doesn't support "-v"
* remove near-duplicate code paths: process_slot(), process_slots(), and state_transition() for BeaconState are now wrappers around the HashedBeaconState versions
* convert tests/test_state_transition.nim to use HashedBeaconState
* convert mocking infrastructure and spec_block/epoch_processing tests to use HashedBeaconBlock, and remove thus unused process_slot*(state: var BeaconState)
* ssz: move ref support outside
Instead of allocating ref's inside SSZ, move it to separate helper:
* makes `ref` allocations explicit
* less magic inside SSZ
* `ref` in nim generally means reference whereas SSZ was loading as
value - if a type indeed used references it would get copies instead of
references to a single value on roundtrip which is unexpected
TODO: EF tests would benefit from some refactoring since they all do the
same thing practically..

In BlockPool, we keep the head state around, so it's trivial to restore
the temporary state there and keep going as if nothing happened.
This solves 3 problems:
* stack space - the state copy on mainnet is huge
* GC scanning - using stack space for state slows down the GC
significantly
* reckless copying - the copy itself takes a long time
In state_sim, we'll do the same and allocate on heap - this helps a
little with GC - without it, the collection of the temporary strings
created with `toHex` while printing the json dominates the trace.
* Add "drop by score" ability to PeerPool.

* switch param orders to group state.{fork, genesis_validators_root}; bump spec/datatypes spec version for network purposes

- Jenkins: we don't need LOG_LEVEL=TRACE twice for the same binaries
- eth2_network_simulation: allow overriding NETWORK_TYPE and
BOOTSTRAP_NODE_NETWORK_TYPE from the environment
We no longer discriminate between ENR, MultiAddress or ENode
bootstrap records (all of them are remapped to ENodes).
The discovery loop will stochastically try to reconnect to
accidentally disconnected nodes.
