158 - ETH Handling

Contracts that accept/manage/transfer ETH should ensure that:

Functions handling ETH are using msg.value appropriately
Logic that depends on ETH value accounts for less/more ETH sent
Logic that depends on contract ETH balance accounts for the different direct/indirect (e.g. coinbase transaction selfdestruct recipient) ways of receiving ETH and transfers are reentrancy safe.

Functions handling ETH should be checked extra carefully for access control, input validation and error handling.
