09ca12ccef Refactor UBT to use an interface (IActionGraphBuilder) to construct the action graph. Response files are also constructed through this interface, allowing them to be tracked as dependencies (will be added in subsequent change).

08aa889a34 UBT: Use the cached filesystem attributes to figure out which files are part of the adaptive non-unity working set. Much faster than querying directly because (a) they're cached, and (b) they're enumerated via a directory scan, which fetches the metadata up front.

e74aff4e60 UBT: Allow pre-build steps to do things that may invalidate the makefile. After loading a makefile, we validate that anything that can affect the pre-build scripts and execute them, then check whether the makefile is still valid for the working set of source files. If not, we discard the makefile and rebuild it (without executing the pre-build steps).

65f542835b UBT: When a response file is updated, rename the old one rather than dumping it to the log. Some of the trace listeners are very slow (eg. the OutputDebugString one), and writing a large amount of text can significantly affect performance.

c5b6fefcc7 UBT: Add a DirectoryItem class, similar to FileItem, which caches directory contents and properties. Allows constructing FileItem objects from enumerated FileInfo objects, avoiding additional I/O hit to determine attributes. DirectoryLookupCache is converted to use DirectoryItem objects as part of this change.

f01ddb51ae UBT: Add support for building multiple targets in parallel. 
* A makefile is now constructed for each target, and the outdated actions are combined into a single graph before execution.
* Makefiles are used in all build modes, regardless of whether they are saved to disk, and represent the vector by which a target's build actions are passed to the executor.
* The -JsonExport= argument has been removed, and a separate JsonExport mode has been added (invoke with eg. "-Mode=JsonExport UE4Editor Win64 Development")
* Multiple action history files are kept open at one time, and a hierarchy is used for each target.

0c9707d678 UBT: Use compiler-generated dependency information for source file dependencies. This ensures that the dependency list is accurate, and makes incremental builds more reliable. 
* A standalone Win32 application called cl-filter is used to parse output from running the Visual Studio compiler with the /showIncludes option, and generate a dependency list similar to Clang.
* Actions which produce an external dependency list declare it explicitly. If the dependency list is missing, or any of the contents are out of date, the action is rebuilt.
* The contents of dependency lists are cached by the CppDependencyCache class for future iterations.
