Close XPC connection between UI process and WebContent process
https://bugs.webkit.org/show_bug.cgi?id=269574
rdar://115840818
Reviewed by Chris Dumez.
Close XPC connection between UI process and WebContent process after launch,
since the XPC connection
should no longer be needed then. This feature flag can only be enabled when
WebKit processes are
launched as extensions, since the lifetime of XPC services are closely related
to the lifetime of the
XPC connection. The audit token needs to be cached in the Connection object,
since it cannot be
retrieved after the XPC connection has been closed. This patch also adds a
missing call to the
completion handler in maybeInitializeSandboxExtensionHandle, which was observed
during the work on
this patch. This change has been validated locally on iOS where WebKit
processes are launched as
extensions.
