This change allows the client to directly send and receive DevTools protocol messages (send method calls, and receive method results and events) without requiring a DevTools front-end or remote-debugging session. This change includes additional supporting changes: - Add a new CefRequestHandler::OnDocumentAvailableInMainFrame callback (see issue #1454). - Add a CefParseJSON variant that accepts a UTF8-encoded buffer. - Add a `--devtools-protocol-log-file=<path>` command-line flag for logging protocol messages sent to/from the DevTools front-end while it is displayed. This is useful for understanding existing DevTools protocol usage. - Add a new "libcef_static_unittests" executable target to support light-weight unit tests of libcef_static internals (e.g. without requiring exposure via the CEF API). Files to be unittested are placed in the new "libcef_static_unittested" source_set which is then included by both the existing libcef_static library and the new unittests executable target. - Linux: Remove use_bundled_fontconfig=false, which is no longer required and causes unittest build errors (see issue #2424). This change also adds a cefclient demo for configuring offline mode using the DevTools protocol (fixes issue #245). This is controlled by the "Offline mode" context menu option and the `--offline` command-line switch which will launch cefclient in offline mode. When cefclient is offline all network requests will fail with ERR_INTERNET_DISCONNECTED and navigator.onLine will return false when called from JavaScript in any frame. This mode is per-browser so newly created browser windows will have the default mode. Note that configuring offline mode in this way will not update the Network tab UI ("Throtting" option) in a displayed DevTools front-end instance.
