Currently all http handlers reply to HTTP/1.1 requests with
chunked responses. This patch allows handlers to opt-out of
that behavior by pre-declaring their Content-Length (which is
then enforced) and unsetting their Transfer-Encoding or
setting it to the "identity" encoding.

It's a little confusing that os.TempDir and ioutil.TempDir have
different meanings. I don't know what to change the names to,
if anything. At least they also have different signatures.

Detect when scan is being called recursively and
re-use the same scan state.
On my machine, for a recursion-heavy benchmark, this
results in 44x speed up. This does impose a 4% penalty
on the non-recursive case, which can be removed by
heap-allocating the saved state, at 40% performance penalty
on the recursive case. Either way is fine with me.

This change makes it possible to take the address of a
struct field or slice element in order to call a method that
requires a pointer receiver.
Existing code that uses the Value.Addr method will have
to change (as gob does in this CL) to call UnsafeAddr instead.

This borrows a trick from the bzip2 source and effects a decent speed
up when decompressing highly compressed sources. Rather than unshuffle
the BTW block when performing the IBTW, a linked-list is threaded
through the array, in place. This improves cache hit rates.

This change removes the special case which existed
for handling the initalization of the main package,
so that other modules named 'main' get properly
initialized when imported.
Note that gotest of main packages will break in most
cases without this.

files get put in _obj, but it's too much - everything

Add a new Read method to ScanState so that it
satisfies the io.Reader interface; rename
Getrune and Ungetrune to ReadRune and UnreadRune.
Make sure ReadRune does not read past width restrictions;
remove now-unnecessary Width method from ScanState.
Also make the documentation a little clearer as to
how ReadRune and UnreadRune are used.

The plan is to keep Client's zero value be a usable
