<pre>[MediaStream][Mac] Revoke sandbox extensions when capture ends
https://bugs.webkit.org/show_bug.cgi?id=165476
Reviewed by Brady Eidson.
Track media capture by process so it is possible to revoke the sandbox extensions issued to
a web process when capture stops.
* CMakeLists.txt: Add new files.
* UIProcess/UserMediaPermissionRequestManagerProxy.cpp:
(WebKit::UserMediaPermissionRequestManagerProxy::UserMediaPermissionRequestManagerProxy): Register
with process manager.
(WebKit::UserMediaPermissionRequestManagerProxy::~UserMediaPermissionRequestManagerProxy):
(WebKit::UserMediaPermissionRequestManagerProxy::userMediaAccessWasGranted): Move sandbox
extension code to the process manager.
(WebKit::UserMediaPermissionRequestManagerProxy::stopCapture): New.
(WebKit::UserMediaPermissionRequestManagerProxy::startedCaptureSession): New, report state
change to the process manager.
(WebKit::UserMediaPermissionRequestManagerProxy::endedCaptureSession): Ditto.
* UIProcess/UserMediaPermissionRequestManagerProxy.h:

manager proxy.
* UIProcess/WebPageProxy.h:
* WebKit2.xcodeproj/project.pbxproj: Add new files.

is now in a HashMap, not a Vector.
