Store NEF in contract state

0b26b46234 state: store NEF instead of script for contract 
NEFs for native contracts are set statically, thus
field values are taken from the reference implementation.

b7e86fa6a3 manifest: add Safe flag to method descriptor 
`interop.Contex.AddMethod` sets `Safe` flag for native
contracts. This allows not to forget to change manifest

2fee69f26f core: add missing onPersist and postPersist methods to natives 
Although not every contract is persisted (see
https://github.com/neo-project/neo/blob/master/src/neo/Ledger/Blockchain.cs#L94)
we have to add `onPersist` and `postPersist` methods to every
native contract in order to display them in manifest for users and
follow C# behaviour. In C# there are `onPersist` and `postPersist`
methods in base native contract class, see
https://github.com/neo-project/neo/blob/master/src/neo/SmartContract/Native/NativeContract.cs#L141

0232bbcb0c core: refactor GASRecord handling 
We should store each GAS record as

}
So don't use state.GASRecord for storing anymore. However, it's still
useful to cache GasRecord values by using state.GASRecords, because we
have to keep GASIndexPairs sorted by indexes.

eccf639803 core: add InitializeCache method to NEO native contracts

when 4-nodes privnet is failing after restoring from dump:

7c6cdcbcc9 core: fix bug with policy.MaxVerificationGas 
In 121c9664b we should take into account isValid flag of
NativePolicy contract while retrieving MaxVerificationGas native
policy value. Otherwise we won't be able to get MaxVerificationGas
after the node was restarted, because this value is not truly
stored along with the other native policy values.

This commit fixes bug with headers verification after the  node
restarting with an existing storage:
