I find this confusing, because vCont? is already supposed
to return the supported vCont actions:

 @item vCont?
 @cindex @samp{vCont?} packet
 Request a list of actions supported by the @samp{vCont} packet.

So ISTM that in the perspective of someone reading the manual without
the context we're discussing here, it's not clear at all what
vContSupported is supposed to mean and why not simply always
return the supported vCont actions in reply to vCont?

Is there an advantage to the vContSupported indirection?  I was
originally thinking we'd make the server report "vCont=c;C;t;s;S;r"
directly in its qSupported reply, and gdb would stop using "vCont?"
going forward (if the target supports that qSupported feature).

Thanks,
