Subject: Standalone GN build.

This CL setups up a standalone GN build. You'll need to set gn args similar to:

use_goma = true
clang_use_chrome_plugins = false
pdf_enable_xfa = true
pdf_enable_v8 = true
pdf_is_standalone = true

The third_party/pymock files are needed to make git cl upload work correctly.

+// as the main function of a child process in a multi-process test.
+// This complements the MultiProcessTest class which provides facilities

+//
+// The MULTIPROCESS_TEST_MAIN() macro registers a string -> func_ptr mapping
+// by creating a new global instance of the AppendMultiProcessTest() class
+// this means that by the time that we reach our main() function the mapping
+// is already in place.
+//
+// Example usage:
+//  MULTIPROCESS_TEST_MAIN(a_test_func) {
+//    // Code here runs in a child process.
+//    return 0;
+//  }
+//
+// The prototype of a_test_func is implicitly
