Merge #13774: Return void instead of bool for functions that cannot fail

d78a8dc3e8 Return void instead of bool for functions that cannot fail (practicalswift)

Pull request description:

  Return `void` instead of `bool` for functions that cannot fail:
  * `CBlockTreeDB::ReadReindexing(...)`
  * `CChainState::ResetBlockFailureFlags(...)`
  * `CTxMemPool::addUnchecked(...)`
  * `CWallet::CommitTransaction(...)`
  * `CWallet::LoadDestData(...)`
  * `CWallet::LoadKeyMetadata(...)`
  * `CWallet::LoadScriptMetadata(...)`
  * `CWallet::LoadToWallet(...)`
  * `CWallet::SetHDChain(...)`
  * `CWallet::SetHDSeed(...)`
  * `PendingWalletTx::commit(...)`
  * `RemoveLocal(...)`
  * `SetMinVersion(...)`
  * `StartHTTPServer(...)`
  * `StartRPC(...)`
  * `TorControlConnection::Disconnect(...)`

  Some of the functions can fail by throwing.

  Found by manually inspecting the following candidate functions:

  ```
  $ git grep -E '(^((static|virtual|inline|friend)[^a-z])*[^a-z]*bool [^=]*\(|return true|return false)' -- "*.cpp" "*.h"
  ```
