  1. feat: new transaction verification model 

    Based on feedbacks gathered earlier, we are revising our verification
model with the following changes:

* When validating a transaction, CKB will grab all lock scripts from
  all inputs, and group them based on lock script hash. The script in
  each group will only be run once. The lock script itself will have
  to do the validation task for all inputs in the same group
* CKB will also grab all type scripts from inputs and outputs(notice
  different from previous version, the type scripts in inputs are
  included here as well), and group them based on type script hash as
  well. Each type script in each group will also be run once. The type
  script itself needs to handle the validation task within the group
* Syscalls are also revised to allow fetching all the
  inputs/outputs/witnesses within a single group.

The default secp256k1_blake160_sighash_all lock script is compiled
from the following source:

https://github.com/nervosnetwork/ckb-system-scripts/blob/e00ba451dccb7a516454ea9606de3a21c8f9a80c/c/secp256k1_blake160_sighash_all.c

The exact gcc version used in the compilation can be located in the
following docker image:
