2b5306a94b Add missing clobbers to context switching
This only shows in release mode, the compiler tries to preserve some
value in rdi, but that gets replaced inside the fiber. This would not
happen in the C calling convention, but in these normal Zig functions,
it can happen.

a5d8dcc025 std.Io.Threaded.netReceive: recvmsg first, then poll
Calling recvmsg first means no poll syscall needed when messages are
already in the operating system queue. Empirically, this happens when
repeating a DNS query that has been already been made recently. In such
case, poll() is never called!

47f18ee6a0 std.Io.net: make netSend support multiple messages
this lowers to sendmmsg on linux, and means Io.Group is no longer
needed, resulting in a more efficient implementation.

888bf35ab0 Io.net: use resolve for IPv6
/etc/resolv.conf might have IPv6 addresses with scope in it, so this is
needed.

dac7ae1e43 Io.net: rework IPv6 parsing and printing
extract pure functional logic into pure functions and then layer the
scope crap on top properly

the formatting code incorrectly didn't do the reverse operation
(if_indextoname). fix that with some TODO panics

806214797a std.Io: rename go to asyncDetached
it's a better name because it's more descriptive, not a reference, and
hints that it is less common than async

708bac1a57 EventLoop: fix futex usage
How silly of me to forget that the kernel doesn't implement its own API.
The scheduling is not great, but at least doesn't deadlock or hammer.
