The smtp package originally allowed PLAIN whenever, but then
the TLS check was added for paranoia, but it's too paranoid:
it prevents using PLAIN auth even from localhost to localhost
when the server advertises PLAIN support.
This CL also permits the client to send PLAIN if the server
advertises it.

Save an allocation per GET request and don't call io.LimitedReader(r, 0)
just to read 0 bytes. There's already an eofReader global variable
for when we just want a non-nil io.Reader to immediately EOF.
(Sorry, I know Rob told me to stop, but I was bored on the plane and
wrote this before I received the recent "please, really stop" email.)

This changes the map lookup behavior for string maps with 2-8 keys.
There was already previously a fastpath for 0 items and 1 item.
Now, if a string-keyed map has <= 8 items, first check all the
keys for length first. If only one has the right length, then
just check it for equality and avoid hashing altogether. Once
the map has more than 8 items, always hash like normal.
I don't know why some of the other non-string map benchmarks
got faster. This was with benchtime=2s, multiple times. I haven't
anything else getting slower, though.

It was unnecessarily cloning and then mutating a map that had
a very short lifetime (just that function).
No new tests, because they were added in revision 833bf2ef1527
(TestHeaderToWire). The benchmarks below are from the earlier
commit, revision 52e3407d.
I noticed this inefficiency when reviewing a change Peter Buhr
is looking into, which will also use these benchmarks.

A package file may begin as either "package foo" or
"package foo safe". The latter is relevant when using -u.
https://golang.org/cl/6903059 resulted in the distinction
being dropped when a package was read for the second or later time.
This CL records whether that "safe" tag was present,
and includes it in the dummy statement generated for the lexer.

The expected precision setting for the x87 on Win32 is 53-bit
but MinGW resets the floating point unit to 64-bit. Win32
object code generally expects values to be rounded to double,

Doing grow work on reads is not multithreaded safe.
Changed code to do grow work only on inserts & deletes.

Since we can't properly handle anything except 100, treat all
1xx informational responses as sketchy and don't reuse the
connection for future requests.
The only other 1xx response code currently in use in the wild
is WebSockets' use of "101 Switching Protocols", but our
code.google.com/p/go.net/websockets doesn't use Client or
Transport: it uses ReadResponse directly, so is unaffected by
this CL. (and its tests still pass)
So this CL is entirely just future-proofing paranoia.
Also: the Internet is weird.
