This commit splits the eth package, separating the handling of eth and snap protocols. It also includes the capability to run snap sync (https://github.com/ethereum/devp2p/blob/master/caps/snap.md) , but does not enable it by default.

This commit fixes a flaw in two testcases, and brings down the exec-time from ~40s to ~8s for trie/TestIncompleteSync.
The checkConsistency was performed over and over again on the complete set of nodes, not just the recently added, turning it into a quadratic runtime.
* core/state/snapshot: print warning if failed to resolve journal
* core/state/snapshot: fix snapshot recovery
When we meet the snapshot journal consisted with:
- disk layer generator with new-format
- diff layer journal with old-format
The base layer should be returned without error.
The broken diff layer can be reconstructed later
but we definitely don't want to reconstruct the
huge diff layer.
* core: add tests
* core/state/snapshot: introduce snapshot journal version
* core: update the disk layer in an atomic way
* core: persist the disk layer generator periodically
* core/state/snapshot: improve logging
* core/state/snapshot: forcibly ensure the legacy snapshot is matched
* core/state/snapshot: add debug logs
* core, tests: fix tests and special recovery case
* core: polish
* core: add more blockchain tests for snapshot recovery
* core/state: fix comment
* core: add recovery flag for snapshot
* core: add restart after start-after-crash tests
* core/rawdb: fix imports
* core: fix tests
* core: remove log
* core/state/snapshot: fix snapshot
* core: avoid callbacks in SetHead
* core: fix setHead cornercase where the threshold root has state
* core: small docs for the test cases

* core/state/snapshot: add diskRoot function
* core/state/snapshot: disable iteration if the snapshot is generating
* core/state/snapshot: simplify the function
* core/state: panic for undefined layer
* core/state/snapshot: exit Geth if generator hits missing trie nodes

* core/state/snapshot: don't enable logging on the tests
This change introduces garbage collection for the light client. Historical
chain data is deleted periodically. If you want to disable the GC, use
the --light.nopruning flag.
This PR implements the EVM state transition tool, which is intended
to be the replacement for our retesteth client implementation.
Documentation is present in the cmd/evm/README.md file.

* core/state: more verbose stateb errors
* core/state: fix flaw
* core/state: fixed lint

This finally adds the error check that the documentation of StateDB.dbErr
promises to do. dbErr was added in 9e5f03b6c (June 2017), and the check was
already missing in that commit. We somehow survived without it for three years.
* core/state/snapshot: implement storage iterator
* core/state/snapshot, tests: implement helper function
* core/state/snapshot: fix storage issue
If an account is deleted in the tx_1 but recreated in the tx_2,
the it can happen that in this diff layer, both destructedSet
and storageData records this account. In this case, the storage
iterator should be able to iterate the slots belong to new account
but disable further iteration in deeper layers(belong to old account)
* core/state/snapshot: address peter and martin's comment
* core/state: address comments
* core/state/snapshot: fix test
* all: seperate consensus error and evm internal error
There are actually two types of error will be returned when
a tranaction/message call is executed: (a) consensus error
(b) evm internal error. The former should be converted to
a consensus issue, e.g. The sender doesn't enough asset to
purchase the gas it specifies. The latter is allowed since
evm itself is a blackbox and internal error is allowed to happen.
This PR emphasizes the difference by introducing a executionResult
structure. The evm error is embedded inside. So if any error
returned, it indicates consensus issue happens.
And also this PR improve the `EstimateGas` API to return the concrete
revert reason if the transaction always fails
* all: polish
* accounts/abi/bind/backends: add tests
* accounts/abi/bind/backends, internal: cleanup error message
* all: address comments
* core: fix lint
* accounts, core, eth, internal: address comments
* accounts, internal: resolve revert reason if possible
* accounts, internal: address comments
This new API allows reading accounts and their content by address range.
