Jacek Sieka f06df1cea6 remove some copies
* in makeBeaconBlock - use rollback instead
* in tests - this helps state_sim give more accurate data and makes it
30% faster
* fix some usages of raw BeaconState

begin removing plain BeaconState versions of state transition functions (#951)
* 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)

avoid state copy in state transition (#930)
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.
