This file can be used as input to a number of other scripts and tools, for example, to graph the dependencies, or to allow higher-level build-config tools to automatically enable component requirements, etc. The first patch of this set generates the basic dependency tree. The second patch does some processing of that dependency tree to identify cases where dependencies are being unnecessarily specified. Reducing these makes it easier to have readable dependency graphs in future, without affecting the build. The following 4 patches are based on the output of the second patch, and greatly cut down the number of direct dependency links between components. Even with the cut-down dependencies, the full dependency graph is nigh-unreadable, so the final patch adds a new script to generate dependency tree subgraphs, creating dot files for e.g. the dependencies of a particular component, or a component class such as mempool drivers.
