/*
Uses MofN CC's normal msig handling to create automated deposits -> token issuing. And partial signing by the selected pubkeys for releasing the funds. A user would be able to select which pubkeys to use to construct the automated deposit/redeem multisigs.
the potential pubkeys to be used would be based on active oracle data providers with recent activity.
bind asset <-> KMD gateway deposit address
KMD deposit -> globally spendable marker utxo
spend marker utxo and spend linked/locked asset to user's CC address
redeem -> asset to global CC address with withdraw address -> gateway spendable marker utxo
spend market utxo and withdraw from gateway deposit address
rpc calls:
GatewayList
GatewayInfo bindtxid
GatewayBind coin tokenid M N pubkey(s)
external: deposit to depositaddr with claimpubkey
GatewayDeposit coin tokenid external.deposittxid -> markertxid
GatewayClaim coin tokenid external.deposittxid markertxid -> spend marker and deposit asset
GatewayWithdraw coin tokenid withdrawaddr
external: do withdraw to withdrawaddr and spend marker, support for partial signatures and autocomplete
deposit addr can be 1 to MofN pubkeys
1:1 gateway with native coin
In order to create a new gateway it is necessary to follow some strict steps.
1. create a token with the max possible supply that will be issued
2. transfer 100% of them to the gateways CC's global pubkey's asset CC address. (yes it is a bit confusing)
3. create an oracle with the identical name, ie. KMD and format must start with Ihh (height, blockhash, merkleroot)
4. register a publisher and fund it with a subscribe. there will be a special client app that will automatically publish the merkleroots.
5. Now a gatewaysbind can bind an external coin to an asset, along with the oracle for the merkleroots. the txid from the bind is used in most of the other gateways CC calls

now the asset is in the pubkey's asset address!
it can be used, traded freely and any node who has the asset can do a gatewayswithdraw

Now there is a withdraw pending, so it needs to be processed by the signing nodes on the KMD side
gatewayspending bindtxid coin
gatewayspending will display all pending withdraws and if it is done on one of the msigpubkeys, then it will queue it for processing

Implementation Issues:
-- When thinking about validation, it is clear that we cant use EVAL_ASSETS for the locked coins as there wont be any enforcement of the gateways locking.
-- This means we need a way to transfer assets into gateways outputs and back. It seems a tokenconvert rpc will be needed and hopefully that will be enough to make it all work properly.
++ The use of tokenconvert has been changed to the use of the new Tokens contract which can enforce other contracts validation by forwarding eval->validate call to GatewaysValidate
++ So all tokens remain within that Tokens contract eval code.
-- Care must be taken so that tokens are not lost and can be converted back.
-- This changes the usage to require tokenconvert before doing the bind and also tokenconvert before doing a withdraw. EVAL_GATEWAYS has evalcode of 241
++ tokenconvert now returns 'not implemented', no need to use it at all.
-- The gatewaysclaim automatically converts the deposit amount of tokens back to EVAL_ASSETS.
++ The gatewaysclaim automatically transfers the deposit amount of tokens to depositor's address (within EVAL_TOKENS).
