Description Brent Fulgham 2020-12-11 10:42:03 PST
Now that the work on the Private Click Measurement standard is approaching consensus we need to make the setting available to clients.

(See <https://github.com/privacycg/private-click-measurement> for background on the feature).

This patch creates a WebKit preference that developers can use to disable PCM if they do not wish their applications to participate in such measurements.

Let's not add more C API unless we really need it.

This line is not necessary and is duplicating work done by the generated preferences code.
