runtime: Check callers in can_recover if return address	doesn't match.

Also use __builtin_extract_return_address and tighten up the
checks in FFI code.

Fixes PR 60406.

refect: fix direct call of variadic method value

As reported in bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61877
gcc mainline has regressed in this.  This CL adds the tests proposed
for the main Go repository:

        https://codereview.appspot.com/151280043/
        https://codereview.appspot.com/152060043/

restores the code from the amd64/386 path that makes this work and
was lost when the Go 1.3 stdlib was merged and changes the FFI path
to call into the same helper code as the amd64/386 path.

I've only tested this on amd64 but I did test a version that was
patched to unconditionally take the FFI path.

f89b66f5ad net: work around Solaris connect issue when server closes socket
On Solaris, if you do a in-progress connect, and then the
server accepts and closes the socket, the client's later
attempt to complete the connect will fail with EINVAL.  Handle
this case by assuming that the connect succeeded.  This code
is weird enough that it is implemented as Solaris-only so that
it doesn't hide a real error on a different OS.

See http://golang.org/issue/6828.

net: use DialTimeout in TestSelfConnect

Backported from master repository.

This avoids problems with systems that take a long time to
find out nothing is listening, while still testing for the
self-connect misfeature since a self-connect should be fast.
With this we may be able to remove the test for non-Linux
systems.

Tested (on GNU/Linux) by editing selfConnect in
tcpsock_posix.go to always return false and verifying that
TestSelfConnect then fails with and without this change.

Idea from Uros Bizjak.
