kernel: Add notification interface 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. Define a new kernel notification class with virtual methods for notifying about internal kernel events. Create a new file in the node library for defining a function creating the default set of notification methods such that these do not need to be re-defined all over the codebase. As a first step, add a `blockTip` method, wrapping `uiInterface.NotifyBlockTip`.

kernel: Add fatalError method to notifications FatalError replaces what previously was the AbortNode function in shutdown.cpp. This commit is part of the libbitcoinkernel project and further removes the shutdown's and, more generally, the kernel library's dependency on interface_ui with a kernel notification method. By removing interface_ui from the kernel library, its dependency on boost is reduced to just boost::multi_index.

kernel: Add flushError method to notifications This is done in addition with the following commit. Both have the goal of getting rid of direct calls to AbortNode from kernel code. This extra flushError method is added to notify specifically about errors that arrise when flushing (syncing) block data to disk. Unlike other instances, the current calls to AbortNode in the blockstorage flush functions do not report an error to their callers. This commit is part of the libbitcoinkernel project and further removes the shutdown's and, more generally, the kernel library's dependency on interface_ui with a kernel notification method. By removing interface_ui from the kernel library, its dependency on boost is reduced to just boost::multi_index. At the same time it also takes a step towards de-globalising the interrupt infrastructure.
