The server_supports_v2() helper lets a caller find out if the server
supports a feature, and will optionally die if it's not supported. This
makes the return value confusing, as it's only meaningful when the
function is not asked to die.
Coverity flagged a new call like:
/* check that we support "foo" */
server_supports_v2("foo", 1);
complaining that we usually checked the return value, but this time we
didn't. But this call is correct, and other ones that did:
if (server_supports_v2("foo", 1))
do_something_with_foo();
are "wrong", in the sense that we know the conditional will always be
true (but there's no bug; the code is simply misleading).
Let's split the "die" behavior into its own function which returns void,
and modify each caller to use the correct one.
