[WIP]cmd, core: resolve scheme from a read-write database

[sysvm]

Description

This pull request solves four pull requests: #2110, #2131, #2141, #2146

1. The first question: resolve state scheme from a read-write database:

This issue can occur when unclean shutdown happens and freezer tables need to be repair. In database read-only mode, the freezer will only be validated but not repair and terminates the node abnormally.
This pull request moves the scheme check into the Ethereum constructor where the read-write database is already initialized. This approach can avoid opening read-only database in very early stage, to prevent this error totally.

2. The second question: ancient directory should be compatible with hash and path mode:

Current geth doesn't deal with chain freezer dir in a good way. Therefore, this pr refactors resolveChainFreezerDir to fix in pruned and non-pruned mode.

Rationale

These will influence how should users use pruenancient mode that block data could be replaced in which.

some PRs are from go-ethereum
so I think, we can format this PR:
PR from go-ethereum use cherry-pick and solve conflict
