[WPE] WPEPlatform add WPEProcessManager to allow embedder launch the
auxiliary processes
https://bugs.webkit.org/show_bug.cgi?id=317845
Reviewed by Carlos Garcia Campos and Adrian Perez de Castro.
WebKit's auxiliary processes (Web, Network and GPU) are launched by
ProcessLauncherGLib via g_subprocess_launcher_spawnv(). That does not work on
platforms where the auxiliary processes cannot be spawned as executables and
must be created by the embedder instead, for example Android, where each process
is a service started with bindService(). With the legacy libwpe API this was
handled by libwpe's process provider, but a WPEPlatform-only build
(ENABLE_WPE_LEGACY_API=OFF) had no equivalent and could only fall back to
spawning executables.
Add a WPEProcessManager abstract class for Android that we subclass to launch
and
terminate auxiliary processes, and register it process-wide with
wpe_process_manager_set_default(). This is currently only needed on Android, so
the WPEProcessManager type is built and exposed only on Android if
WPE_PLATFORM_PROCESS_MANAGER_ANDROID config is defined, and
the ProcessLauncherGLib integration is guarded with OS(ANDROID); other ports
keep the existing subprocess launching and are unaffected. ProcessLauncherGLib
uses the default manager through wpe_process_manager_get_default() when one is
set. The process manager is a system-level facility that does not change at
runtime, so it is a global default rather than a per-WPEDisplay object.
* Source/WebKit/UIProcess/Launcher/glib/ProcessLauncherGLib.cpp: Use the default
WPEProcessManager when set on Android.
