 This is a patch used by the Android app [https://briarproject.org/ Briar]
 (since
 [https://code.briarproject.org/akwizgran/briar/commit/9e5e2e2df24d84135f14adaa42111c3ea2c55df8
 October 2014]) that
 [https://code.briarproject.org/akwizgran/briar/issues/115 we would like to
 upstream]. It adds an `HSFORGET` command to the control protocol which
 clears any cached client state relating to a specified hidden service.
 This can be used to flush state that's likely to be stale before trying to
 connect to a hidden service via an unstable network connection (such as a
 mobile data connection).
