Zahary Karadjov 0bcdabfcdf Detect another invalid SSZ input found through fuzzing
The first offset of an SSZ object should always have a fixed constant
value. Otherwise, some unused bytes may appear between the fixed portion
and the dynamic portion.

Please note that this fix shutds down the minimal forward compatibility
currently supported by the SSZ format (and thus, the expected behavior
must be clarified in the SSZ spec).

Zahary Karadjov 3ecb197635 Memory-optimal hash_tree_root
The work on this was started last week while I was waiting
for a decision on the "Async Snappy" PR. It was prompted by
a failing test in the test suite, where the HashingStream
was inserting some incorrectly padded chunks that affected
the result of `hash_tree_root`. Instead of working around
the problem in the HashingStream, I've decided to implement
a planned optimisation that allows us to remove the hashing
stream altogether.

With the optimisation in place, `hash_tree_root` will now
use only stack memory and only the precise amount neccesary
to build the chunks-merging tree.

ssz: move ref support outside (#943)
* 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..

Zahary Karadjov 22591deced Safer testnet restarts; Working CLI queries for inspecting the genesis states
When the connect_to_testnet script is invoked it will first verify that
the genesis file of the testnet hasn't changed. If it has changed, any
previously created database associated with the testnet will be erased.

To facilitate this, the genesis file of each network is written to the
data folder of the beacon node. The beacon node will refuse to start if
it detects a discrepancy between the data folder and any state snapshot
specified on the command-line.

Since the testnet sharing spec requires us to use SSZ snapshots, the Json
support is now phased out. To help with the transition and to preserve the
functionality of the multinet scripts, the beacon node now supports a CLI
query command that can extract any data from the genesis state. This is
based on new developments in the SSZ navigators.
