TxSelector add CoordIdxDB, SelectionConfig, abstract filtering

TxTypeToEthAddr & TxTypeToBJJ

- TxSelector
	- Add SelectionConfig for each batch
	- Add CoordIdxDB key-value where the CoordinatorIdxs are stored
	- Separated method for filtering TxTypeToEthAddr & TxTypeToBJJ

Fix order of L1UserTxs

When the synchronizer queries the unforged L1UserTxs, sort them by position

Swap the order of calls setL1UserTxEffectiveAmounts and addBatch in
AddBlockSCData because otherwise, for reasons I dont understand, the item_id of
the txs doesn't follow the position of the txs.

Fix panic caused by nil batchInfo.ServerProof

Fix coordinator pipeline forgeBatch call

Merge node (sync-only) and coord config

Make coordinator more robust agains failed forges

Fix format of the MTP for exit endpoint

Update txs constructors and helpers

Add mock proof server

Extend Coordinator tests

For each tx, move the logic of setting the Type and TxID to separate functions,
so that they can be called when necessary.

In synchronizer, set all the required fields using the `SetID` and `SetType`
for l2txs when needed.  This is necessary because the `ProcessTxs()` works with
`common.PoolL2Tx`, which misses some fields from `common.L2Tx`, and because
`ProcessTxs()` needs the Type to be set, but at the same time `ProcessTxs()`
sets the Nonce, which is required for the `TxID`.

Fix inconsistency between api doc and code: hermezEthereumAddress => …

Update StateDB computeEffectiveAmounts

Add TxType before processing L2 tx

For the case of tx.EthAddr!=tx.FromIdx.EthAddr

Fix queries when no rows

Update ZKInputs generation:

Make coordinator more responsive

- API:
	- Replace `emergencyModeStaringTime` by `emercengyModeStartingBlock`
- Synchronizer:
	- Track emergency mode starting block
- cli/node
	- Add working coordinator config
- coordinator:
	- Retry handler for synchronizer stats in case of error (instead of
	  waiting for the next block to try again)
	- On init, trigger an initial call to the handler for synced block
	  before waiting for the synchronizer, to force the coordinator to start
	  its logic even if there's no new block right after the node has been
	  started (very useful for running in testnet where the frequency of
	  blocks is variable)
	- Merge Msg for synced block and updated vars into one: `MsgSyncBlock`.

- Update IntermediateState FinalAccFee values to fit in the Circom circuit expected inputs
- Add ZKInputs generation test with transactions generated by Til
(TestZKInputs6)
- BatchBuilder: remove redundant MakeCheckpoint call

StateDB Exit & ForceExit correct processing & ZKI

- Update tx processor of Exit & ForceExit types
- Update ZKInputs generation related to Exit transactions
- Add TestZKInputs5 which adds tests generation of ZKInputs compatible
with Circom circuits including Exit (L2) & ForceExit (L1) transaction types
- Add StateDB test to check max DepositAmount case

Update synchronizer and DB with last contracts updates

- API
	- When updating network info, handle cases where no batches exists and
	  where no forgers exists
- cli/node
	- Update `cfg.buidler.toml` config file to a working version
- common
	- Add new smart contract structs and extend some existing ones to
	  reflect updates regarding events from the smart contracts
- SQL
	- Add new tables and extend existing ones to reflect updates regarding
	  events from the smart contracts
- db/historydb
	- Add functions to insert new smart contract events data
	- Fix unclosed rows that led to inconsistent sql driver state (replace
	  NamedQuery by NamedExec).  This fixes the error:
	  `pq: unexpected Parse response 'C'`
- db/l2db
	- Close rows after usage
- eth
	- In Rollup event, introduce a new UpdateBucketsParameter when there's a
	  SafeMode event, with `SafeMode = true`
- synchronizer
	- synchronize new events
	- avoid calling `auction.CanForge` before the genesisBlock to avoid
	  getting a revert.

Fix process L1Tx for correct ZKInputs generation

Update prover & add test

- StateDB fix process txs of type CreateAccountDepositTransfer & DepositTransfer
- Add TestZKInputs3 & TestZKInputs4 which:
    - have a compatible check in js version to check Circom circuits
compatibility
    - adds test of tx type of CreateAccountDepositTransfer &
DepositTransfer

Update missing LoadAmount to DepositAmount

Update swagger.yml
