Andrew Kelley 961961cf85 std: fix msghdr and cmsghdr when using musl libc
glibc and linux kernel use size_t for some field lengths while POSIX and
musl use int. This bug would have caused breakage the first time someone
tried to call sendmsg on a 64-bit big endian system when linking musl
libc.

my opinion:
* msghdr.iovlen: kernel and glibc have it right. This field should
  definitely be size_t. With int, the padding bytes are wasted for no
  reason.
* msghdr.controllen: POSIX and musl have it right. 4 bytes is plenty for
  the length, and it saves 4 bytes next to flags.
* cmsghdr.len: POSIX and musl have it right. 4 bytes is plenty for the
  length, and it saves 4 bytes since the other fields are also 32-bits
  each.

Andrew Kelley bcb6760fa5 std.os.linux: remove unnecessary warnings from sendmmsg
The one about INT_MAX is self-evident from the type system.

The one about kernel having bad types doesn't seem accurate as I checked
the source code and it uses size_t for all the appropriate types,
matching the libc struct definition for msghdr and msghdr_const.

Andrew Kelley 3b80fde6f4 std.os.linux: remove sendmmsg workaround
This "fix" is too opinionated to belong here. Better instead to
document the pitfalls.

Andrew Kelley cde5a51d0c 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.

/etc/resolv.conf might have IPv6 addresses with scope in it, so this is
needed.

Andrew Kelley d776a6bbbe 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

it's a better name because it's more descriptive, not a reference, and
