Fix problems found.
On amd64, various library routines had bigger
stack frames than expected, because large function
calls had been added.
runtime.assertI2T: nosplit stack overflow
120 assumed on entry to runtime.assertI2T

On arm, 5c was tagging functions NOSPLIT that should
not have been, like the recursive function printpanics:

108 on entry to printpanics
96 after printpanics uses 12
92 on entry to printpanics

60 on entry to printpanics
48 after printpanics uses 12
44 on entry to printpanics
32 after printpanics uses 12
28 on entry to printpanics

12 on entry to printpanics
0 after printpanics uses 12
-4 on entry to printpanics

Other than maybe cleaning the code up a bit, this has
little practical effect for now, but lays the foundation
for remembering the method set of a type, which can
be expensive.

It was observed that the interface was generic enough
that several other types implemented it too.
Fixes#1530.

Removed a redefinition of the request URL which is never used and
redundant checking of the return value from send().

Using make -C $* rather than (cd $* ; make) results in a small,
but measurable improvement in build times where compilation is
not the major component. eg.
before - ~/go/src/pkg$ time make
real 0m1.176s
user 0m0.639s
sys 0m0.399s
after - ~/go/src/pkg$ time make
real 0m0.916s
user 0m0.571s
sys 0m0.243s
There are other places in the distribution src/make.common for example
that could also benefit from this change.

PKCS#1 v2.1 section 7.1.1 says that the result of an OAEP encryption
is "an octet string of length $k$". Since we didn't left-pad the
result it was previously possible for the result to be smaller when
the most-significant byte was zero.
Fixes#1519.

Flags defined in the testing package may conflict
with real flags defined in the main package, or in
any other imported package.
This change makes them less likely to be used for
other purposes.

I'm not sure if it's 100% correct wrt the HTML5 specification,
but the test suite has plenty of HTML comment test cases, and
we'll shake out any tokenization bugs as the parser improves its
coverage.

notes:
Darwin is very particular about joining a multicast group if the
listneing socket is not created in "udp4" mode, the other supported
OS's are more flexible.
A simple example sets up a socket to listen on the mdns/bonjour
group 224.0.0.251:5353
// ensure the sock is udp4, and the IP is a 4 byte IPv4
socket, err := net.ListenUDP("udp4", &net.UDPAddr {
IP: net.IPv4zero,
// currently darwin will not allow you to bind to
// a port if it is already bound to another process
Port: 5353,
})
if err != nil {
log.Exitf("listen %s", err)
}
defer socket.Close()
err = socket.JoinGroup(net.IPv4(224, 0, 0, 251))
if err != nil {
log.Exitf("join group %s", err)
}
