Merge #14862: doc: Declare BLOCK_VALID_HEADER reserved
fa0b910486e9aada077fe47e1201dcb3bd523c87 [doc] chain: Declare BLOCK_VALID_HEADER reserved (MarcoFalke) Pull request description: `BLOCK_VALID_HEADER` was never used and the comment is confusing to me in several ways: * It claims "version ok". However, without the previous header, it is not possible to check the validity of the version since the height needs to be known (c.f. BIP 90) * It claims "hash satisfies claimed PoW". While it is possible to check against the claimed PoW, it is not possible without the previous header to check that the claimed PoW is itself valid. * It claims "1 <= vtx count <= max". However, with the header alone and current consensus rules, the number of transactions is unknown.
