if their nominal Min and Max points differ.

This is a behavior change, but arguably a bug fix, as Eq wasn't
previously consistent with In, and the concept of a rectangle being a
set of points. This is demonstrated by the new geom_test.go test.

It does mean that r.Eq(s) no longer implies that Inset'ting both r and s
with a negative inset results in two rectangles that are still Eq, but
that seems acceptable to me.

The previous behavior is still available as "r == s".

Also clarify the image.Rect doc comment when the inputs are
non-canonical.

Also simplify the Point and Rectangle Eq implementations dating from
before Go 1.0, when you couldn't compare structs via the == operator.

Env vars were incorrectly copying whole value of http.RemoteAddr
to REMOTE_ADDR and REMOTE_HOST. They contained IP:port pair which
instead should only have IP (RFC 3875, other sources).

Module also was not setting REMOTE_PORT variable which become de-facto
standard for passing TCP client port to CGI scripts (Apache mod_cgi,
IIS, and probably others)

Fixes #8291

There were several complaints about closure names in the issue tracker.
The first problem is that you see names like net/http.func·001
in profiles, traces, etc. And there is no way to figure out what
is that function.
Another issue is non-US-ascii symbols. All programs out there
should accept UTF-8. But unfortunately it is not true in reality.
For example, less does not render middle dot properly.

This change prepends outer function name to closure name and
replaces middle dot with dot. Now names look like:

main.glob.func1
main.glob.func2
main.glob.func2.1
main.init.1
main.init.1.func1
main.init.1.func1.1
main.main.func1
main.main.func1.1

Apparently when ARM stops at a GDB breakpoint, it appears to be in
syscall.Syscall.  The "info goroutines" test expected it to be in a
runtime function.  Since this isn't fundamental to the test, simply
tweak the test's regexp to make sure "info goroutines" prints some
running goroutine with an active M, but don't require it to be in any
particular function.

"info goroutines" is failing because it hasn't kept up with changes in
the 1.5 runtime.  This fixes three issues preventing "info goroutines"
from working.  allg is no longer a linked list, so switch to using the
allgs slice.  The g struct's 'status' field is now called
'atomicstatus', so rename uses of 'status'.  Finally, this was trying
to parse str(pc) as an int, but str(pc) can return symbolic
information after the raw hex value; fix this by stripping everything
after the first space.

This also adds a test for "info goroutines" to runtime-gdb_test, which
was previously quite skeletal.

e.g. ·Name instead of package·Name for automatic stack map to
be applied from its Go prototype.

The underlying reason is that liblink look up name with suffix
".args_stackmap" for the stackmap coming from its Go prototype,
but all the Go functions are named "".Name as this stage. Thus
an assembly function named package·Name will never find its
stackmap, which is named "".package.Name.args_stackmap.

Perhaps cmd/vet should give a warning for this.
