Updated phase 1: branch and early subkey reveal challenges (#587)
* Updated phase 1: branch challenges

* Removed unnecessary line

* Added early subkey reveal slashing

* Revealing during the active period is still revealing early

* Added....

* Machinery for publishing old subkeys
* Inability to withdraw until you published all subkeys
* After a validator exits the queue there's still a minimum 1-day delay before they can withdraw (in the future this delay will be used as an opportunity to start a PoC challenge game)

* Update 1_shard-data-chains.md

* formatting

* minor edits

* Added masking scheme for reveals

Secure under the aggregate extraction infeasibility assumption described on pages 11-12 of https://crypto.stanford.edu/~dabo/pubs/papers/aggreg.pdf

* Added rewards going to challengers

* Add ToC and reorg the constant tables

* Remove tags

* fix constant formatting

* normalize domain constants in phase 1

* Update 1_shard-data-chains.md

* Update 1_shard-data-chains.md

* Update 1_shard-data-chains.md

* Added transition logic

* Fix ToC

* Fix ToC

* Adjusted for #615

* Added more helpers

* epoch -> slot

* fix some type hints

* clean up `get_attestation_merkle_depth`

Fix `compute_commitment`
1. Use `+` to concatenate the merkle roots in `hash` function.
2. Fix `pad_to_power_of_2`: padding with `[b'\x00' * SHARD_BLOCK_SIZE]`,
not `[SHARD_BLOCK_SIZE]`.

vbuterin abed5ffdae Updated phase 1: fork choice rule (#586)
Adds the crosslink committee to the fork choice rule. This is useful because it means that even if a proposal committee is byzantine and attempts to prevent a crosslink via a "balance attack" (alternating between chain A and chain B being the canonical chain), the crosslink committee can force the equilibrium to flip to one side or the other.

* Add shard blocks, shard data roots and how data is computed into crosslinks

Includes:

* Shard block structure
* Shard block header verification rule
* Shard block fork choice rule
* Shard block body verification rule
* Crosslink verification rule

Possible simplification: require `calc_block_maxbytes` to always output an exact power of two; if we desire the average maxbytes to be smooth, we can simply make it a pseudorandom chose between powers. This reduces some of the padding complexity.

* create separate files for phases (#125)

* create separate files for phases

* fix links

* add shard block pre processing conditions

* cleanup

* remove 'essentially'

* Updated handling for beacon chain skipping slots.

* Handle missing slots more

* modify attestation validity rule for crosslink hash
