Since we can't properly handle anything except 100, treat all
1xx informational responses as sketchy and don't reuse the
connection for future requests.
The only other 1xx response code currently in use in the wild
is WebSockets' use of "101 Switching Protocols", but our
code.google.com/p/go.net/websockets doesn't use Client or
Transport: it uses ReadResponse directly, so is unaffected by
this CL. (and its tests still pass)
So this CL is entirely just future-proofing paranoia.
Also: the Internet is weird.

Whoops. I'm surprised it even worked before. (Need two pipes,
not one.)
Also, remove the whole pipe registration business, since it
wasn't even required in the previous version. (I'd later fixed
it at the end of send100Response, but forgot to delete it)

Some packages, like popwin.el, change display behaviour based on
the buffer's mode, so we should enable compilation-mode before

This CL ensures we use the correct socket options for
passive and active open sockets.
For the passive open sockets created by Listen functions,
additional SO_REUSEADDR, SO_REUSEPORT options are required
for the quick service restart and/or multicasting.
For the active open sockets created by Dial functions, no
additional options are required.

"There are only two hard problems in computer science:
cache invalidation, naming things, and off-by-one errors."
The HTTP server code already strips Expect: 100-continue on
requests, so httputil.ReverseProxy should be unaffected, but
some servers send unsolicited HTTP/1.1 100 Continue responses,
so we need to skip over them if they're seen to avoid getting
off-by-one on Transport requests/responses.
This does change the behavior of people who were using Client
or Transport directly and explicitly setting "Expect: 100-continue"
themselves, but it didn't work before anyway. Now instead of the
user code seeing a 100 response and then things blowing up, now
it basically works, except the Transport will still blast away
the full request body immediately. That's the part that needs
to be finished to close this issue.
This is the safe quick fix.
