improve slot processing speeds (#1670) 
about 40% better slot processing times (with LTO enabled) - these don't
do BLS but are used
heavily during replay (state transition = slot + block transition)

tests using a recent medalla state and advancing it 1000 slots:

```
./ncli slots --preState2:state-302271-3c1dbf19-c1f944bf.ssz --slot:1000
--postState2:xx.ssz
```
pre:

```

cache block hash (#1329) 
hash_tree_root was turning up when running beacon_node, turns out to be
repeated hash_tree_root invocations - this pr brings them back down to
normal.

this PR caches the root of a block in the SignedBeaconBlock object -
this has the potential downside that even invalid blocks will be hashed
(as part of deserialization) - later, one could imagine delaying this
until checks have passed

there's also some cleanup of the `cat=` logs which were applied randomly
and haphazardly, and to a large degree are duplicated by other
information in the log statements - in particular, topics fulfill the
same role

Restore compilation with custom presets (#1309)

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).

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.
