The network connection dies differently from the server's
perspective on (some) Windows when the client goes away. Match
on the common prefix (common to Unix and Windows) instead of
the network error part.

For non-closure functions, the context register is uninitialized
on entry and will not be used, but morestack saves it and then the
garbage collector treats it as live. This can be a source of memory
leaks if the context register points at otherwise dead memory.
Avoid this by introducing a parallel set of morestack functions
that clear the context register, and use those for the non-closure functions.
I hope this will help with some of the finalizer flakiness, but it probably won't.
Fixes#7244.

It mentioned true and false for error values. Instead, just
don't mention the error semantics, as they match normal Go
conventions (if error is non-nil, the other value is
meaningless). We generally only document error values when
they're interesting (where non-nil, non-nil is valid, or the
error value can be certain known values or types).

The flakiness appears to be just in tests, not in the actual code.
Specifically, the many tests call runtime.GC once and expect that
the finalizers will be running in the background when GC returns.
Now that the sweep phase is concurrent with execution, however,
the finalizers will not be run until sweep finishes, which might
be quite a bit later. To force sweep to finish, implement runtime.GC
by calling the actual collection twice. The second will complete the
sweep from the first.
This was reliably broken after a few runs before the CL and now
passes tens of runs:
while GOMAXPROCS=2 ./runtime.test -test.run=Finalizer -test.short \
-test.timeout=300s -test.cpu=$(perl -e 'print ("1,2,4," x 100) . "1"')
do true; done

The exception handler runs on the ordinary g stack,
and the stack copier is now trying to do a traceback
across it. That's never been needed before, so it was
unimplemented. Implement it, in all its ugliness.

gccgo considers built-in function calls returning a constant not as function call (issue 7386)
go/types considers any call (regular or built-in) as a function call
The wording and examples clarify that only "function calls" that are issued
at run-time (and thus do not result in a constant result) are considered
function calls in this case.
gc is inconsistent (issue 7385)
gccgo already interprets the spec accordingly and issue 7386 is moot.
go/types considers all calls (constant or not) as function calls (issue 7457).

1) Move StateHijacked callback earlier, to make it
panic-proof. A Hijack followed by a panic didn't previously
result in ConnState getting fired for StateHijacked. Move it
earlier, to the time of hijack.
2) Don't fire StateActive unless any bytes were read off the
wire while waiting for a request. This means we don't
transition from New or Idle to Active if the client
disconnects or times out. This was documented before, but not
implemented properly.

Unfortunately FreeBSD 10 has changed its syscall arguments for
some reasons but as per request at golang-dev this CL does not
generate some structures, syscall numbers and constants as
compatible to FreeBSD 10 as follows:
Structure: Stat_t, IfData, IfMsghdr are based on 8-STABLE
Syscall number: Capsicum API is based on 9-STABLE
Constant: IFT_CARP, SIOCAIFADDR, SIOCSIFPHYADDR are based on 9-STABLE
Update #7193

compliance.

In Go 1.2, closing a request body without reading to EOF
causes the underlying TCP connection to not be reused. This
client code following redirects was never updated when that
happened.
This was part of a previous CL but moved to its own CL at
Josh's request. Now with test too.

Currently a write error will cause future reads to return that same error.
However, there may have been extra information from a peer pending on
the read direction that is now unavailable.
This change splits the single connErr into errors for the read, write and
handshake. (Splitting off the handshake error is needed because both read
and write paths check the handshake error.)

The addition of Server.ConnState provides all the necessary
hooks to stop a Server gracefully, but StateNew previously
could fire concurrently with Serve exiting (as it does when
its net.Listener is closed). This previously meant one
couldn't use a WaitGroup incremented in the StateNew hook
along with calling Wait after Serve. Now you can.
