61fd11ef96 http: allow handlers to send non-chunked responses
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.

9ebe384b71 io/ioutil: add TempDir
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.

5bd284e868 fmt: make recursive scan more efficient.
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.

e46acb091f reflect: add PtrTo, add Value.Addr (old Addr is now UnsafeAddr)
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.

e7fa307902 bzip2: speed up decompression.
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.

fdbbb066ed compress/lzw: don't use a closure in NewReader, which avoids having
to move some variables from the stack to the heap.

Sorted benchmark runs on my 2007-era Mac Mini (GOARCH=amd64, GOOS=linux):

Before:
lzw.BenchmarkDecoder        2000        878176 ns/op
lzw.BenchmarkDecoder        2000        878415 ns/op
lzw.BenchmarkDecoder        2000        880352 ns/op
lzw.BenchmarkDecoder        2000        898445 ns/op
lzw.BenchmarkDecoder        2000        901728 ns/op

After:
lzw.BenchmarkDecoder        2000        859065 ns/op
lzw.BenchmarkDecoder        2000        859402 ns/op
lzw.BenchmarkDecoder        2000        860035 ns/op
lzw.BenchmarkDecoder        2000        860555 ns/op
lzw.BenchmarkDecoder        2000        861109 ns/op

The ratio of before/after median times is 1.024.

The runtime.MemStats.Mallocs delta per loop drops from 109 to 104.
