Subject: Convert `channelmonitor` `vec_type` TLV writes to required/optional
X-Git-Tag: v0.0.116-rc1~7^2~2
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=4b7631ce161c650932f1dfea3539b3f8c9a1eb37;p=rust-lightning

Convert `channelmonitor` `vec_type` TLV writes to required/optional

 * `HolderSignedTx::htlc_outputs` has always been written since it
   was converted to TLVs in 86641ea68062388a01c99c6ed131f56477c8e4.
 * `ChanelMonitorUpdateStep::*::htlc_outputs` have been written
   since the enum was converted to TLVs in 86641ea68062388a01c99c6.
