trivial: it is not a serious problem to leak a fd in a short lived process, but it was obscuring my investigation of issue 5593.

The old code worked, somewhat on accident, but was confusing,
and had a useless assignment to the inner err. It worked
because url.Parse parses just about anything, so the outer err
was always nil, so it always fell through to the bottom return
statement, even without the "err = nil" line.
Instead, just have two return statements, and add a comment.

TLS clients send ciphersuites in preference order (most prefereable
first). This change alters the order so that ECDHE comes before plain
RSA, and RC4 comes before AES (because of the Lucky13 attack).
This is unlikely to have much effect: as a server, the code uses the
client's ciphersuite order by default and, as a client, the non-Go
server probably imposes its order.

The single flag -cover provides the default simplest behavior.
The other flags, -covermode and -coverprofile, provide more
control. The three flags interconnect to work well.

This basic Vim ftplugin sets the 'comments' and 'commentstring'
settings to sensible values. Future filetype settings for Go
would go in the same file.
The ftplugin was added as misc/vim/ftplugin/go/go.vim, this way
the installation instructions in readme.txt remain valid.
Fixes#5715.

It was used to request large stack segment for GC
when it was running not on g0.
Now GC is running on g0 with large stack,
and it is not needed anymore.

In Issue 5625, Russ says: "We should at least have a cache of
inflight lookups, so that 100 simultaneous dials of one host
name don't do the work 100x. That's easy and (assume we forget
the answer once they all get it) doesn't pose any consistency
problems. It just merges simultaneous work."
This brings in singleflight (unexported) from Google /
Camlistore, but without its tests. Maybe we should put it
somewhere in the standard library. But not now.
Update #5625
