Bug 548730 - Compilation database (CDB) language settings provider
This language settings provider lets you specify the path to the compile_commands.json and reuses existing build output parsers to figure out all the language entries for each file to be used while indexing. With this, there is no need to do a full build and in fact no need to have a working build configured in CDT for indexing to work and be fully configured. This is especially useful for non-CMake build systems that have no existing integration in CDT but indexing would still works with little effort. The build output parser (GCC, MSVC, etc) is selectable as part of the configuration of the CDB provider. There is also an option to exclude any file that is not present in the CDB. This option is useful for large projects in order to speed up indexing but also to increase index accuracy (conflicting symbol names, etc).
