There was a typo introduced in the initial
implementation of the Plan 9 support of
the mime package.

On Plan 9, the mime type file name should be
/sys/lib/mimetype instead of /sys/lib/mimetypes.

Currently the heapBitsSetType documentation says that there are no
races on the heap bitmap, but that isn't exactly true. There are no
*write-write* races, but there are read-write races. Expand the
documentation to explain this and why it's okay.

Currently we only execute a publication barrier for scan objects (and
skip it for noscan objects). This used to be okay because GC would
never consult the object itself (so it wouldn't observe uninitialized
memory even if it found a pointer to a noscan object), and the heap
bitmap was pre-initialized to noscan.

However, now we explicitly initialize the heap bitmap for noscan
objects when we allocate them. While the GC will still never consult
the contents of a noscan object, it does need to see the initialized
heap bitmap. Hence, we need to execute a publication barrier to make
the bitmap visible before user code can expose a pointer to the newly
allocated object even for noscan objects.

This fixes change https://go-review.googlesource.com/#/c/23069/, which
assumes all DNS requests are UDP. This is not true -- DNS requests can
be TCP in some cases. See:
https://tip.golang.org/src/net/dnsclient_unix.go#L154
https://en.wikipedia.org/wiki/Domain_Name_System#Protocol_transport

Also, the test code added by the above change doesn't actually test
anything because the test uses a faked DNS resolver that doesn't
actually make any DNS queries. I fixed that by adding another test
that uses the system DNS resolver.

The httptrace.ConnectStart and ConnectDone hooks are just about the
post-DNS connection to the host. We were accidentally also firing on
the UDP dials to DNS. Exclude those for now. We can add them back
later as separate hooks if desired. (but they'd only work for pure Go
DNS)

This wasn't noticed earlier because I was developing on a Mac at the
time, which always uses cgo for DNS. When running other tests on
Linux, I started seeing UDP dials.

This is addressing feedback given on golang.org/cl/23052;
we do it in a separate CL to separate the functional from
the rename change.

ONAME was not used in the export data, but it's the natural node op
where we used OPACK instead. Renamed.

Furthermore, OPACK and ONONAME nodes are replaced by the type checker
with ONAME nodes, so OPACK nodes cannot occur when exporting type-checked
code. Removed a special-case for OPACK nodes since they don't appear.
