kernel: Add warning method to notifications
This commit is part of the libbitcoinkernel project and seeks to remove the ChainstateManager's and, more generally, the kernel library's dependency on interface_ui with options methods in this and the following few commits. By removing interface_ui from the kernel library, its dependency on boost is reduced to just boost::multi_index. The DoWarning and AlertNotify functions are moved out of the validation.cpp file, which removes its dependency on interface_ui as well as util/system.
