Closes#8069
* Type `ABCIResponses` was just wrapping type `ResponseFinalizeBlock`. This patch removes the former.
* Did some renaming to avoid confusion on the data structure we are working with.
* We also remove any stale ABCIResponses we may have in the state store at the time of pruning
**IMPORTANT**: There is an undesirable side-effect of the unwrapping. An empty `ResponseFinalizeBlock` yields a 0-length proto-buf serialized buffer. This was not the case with `ABCIResponses`. I have added an interim solution, but open for suggestions on more elegant ones.
## Description
Internalize some libs. This reduces the amount ot public API tendermint is supporting. The moved libraries are mainly ones that are used within Tendermint-core.
## Description
I'm just doing a self audit of the light client. There's a few things I've changed
- Validate trust level in `VerifyNonAdjacent` function
- Make errNoWitnesses public (it's something people running software on top of a light client should be able to parse)
- Remove `ChainID` check of witnesses on start up. We do this already when we compare the first header with witnesses
- Remove `ChainID()` from provider interface

## Description
This PR wraps the stdlib sync.(RW)Mutex & godeadlock.(RW)Mutex. This enables using go-deadlock via a build flag instead of using sed to replace sync with godeadlock in all files
