chg: send type information via S channel (BC) Previously S channel is only used to send system commands. It will also be used to send pager commands. So add a type parameter. This breaks older chg clients. But chg and hg should always come from a single commit and be packed into a single package. Supporting running inconsistent versions of chg and hg seems to be unnecessarily complicated with little benefit. So just make the change and assume people won't use inconsistent chg with hg.
