Txn validation stages

[xandkar]

Continuation of @Vagabond's work started in https://github.com/helium/blockchain-core/tree/adt/validation-stages . Rebase was messy, so I started from scratch.

TODO

general

• [ ] limits.hrl
  • [ ] 32, 64 bit int, etc
• [ ] convert int {min, N}s to {range, N, ?MAX_INT64}?
• [-] take ledger instead of chain arg
  • [~] is_absorbable XXX Reverted, because chain is used to lookup validation parameters in some txs, at least the bundle looks up the max size chain var.
  • [~] absorb XXX Chain is passed to blockchain_ledger_v1:debit_fee in several txns
    • [ ] decide
      • keep chain param or
      • grab chain from blockchain_worker?
• [x] maybe a ternary codomain, rather than just boolean, because a bad nonce may mean a txn is still absorbable in some (bound) future
  • yes | no | not_yet
• [x] opportunistically re-order so that expensive things (e.g. crypto) are checked last (or not at all if previous checks fail)
• [x] remove unused modules:
  • [x] src/transactions/v1/blockchain_txn_token_burn_exchange_rate_v1.erl
• [x] better generic value validation library
• mark long is_valids for later factorization, to be done in another PR
