Subject: DecodedOnionFailure::payment_retryable -> ::payment_failed_permanently
X-Git-Tag: v0.0.117-alpha2~8^2~3
X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=9c41f129c0da084e33f6c367b9ab58df3b0fd586;p=rust-lightning

DecodedOnionFailure::payment_retryable -> ::payment_failed_permanently

Our ultimate goal with this field is to set
PaymentPathFailed::payment_failed_permanently, so use this name rather than
flipping a bool back and forth across methods.
