An optimization in Transport which re-uses TCP
connections early in the case where there is
no response body interacted poorly with
ErrBodyReadAfterClose. Upon recycling the TCP
connection early we would Close the Response.Body
(in case the user forgot to), but in the case
of a zero-lengthed body, the user's handler might
not have run yet.
This CL makes sure the Transport doesn't try
to Close requests when we're about to immediately
re-use the TCP connection.
This also includes additional tests I wrote
while debugging.

crl parses CRLs and exposes their details. In the future, Verify

So far, only top-level names where considered when trimming ASTs
using a filter function. For instance, "godoc reflect Implements"
didn't show the "Implements" method of the type Interface because
the local method name was not considered (on the other hand, "top-
level" declared methods associated with types were considered).
With this CL, AST filter functions look also at struct fields
and interface methods.

writing the idct result directly to the image buffer instead of
storing it in an intermediate d.blocks field.
Writing to d.blocks was necessary when decoding to an image.RGBA image,
but now that we decode to a ycbcr.YCbCr we can write each component
directly to the image buffer.
Crude "time ./6.out" scores to decode a specific 2592x1944 JPEG 20
times show a 16% speed-up:

When traversing parameter lists (e.g. for type checking), we want the
invariant that all identifers have associated objects (even _ idents),
so that we can associate a type with each object.

At least, as I understand it. The spec is unclear about what happens
with a local color map.

This change fixes generation of "shadow" variables for bool parameters.
Before the change, it was naming all bool variables with the same name of _p0.
Now it calls them _p0, _p1, ... So the code could compile.

It's incomplete but sufficient to decode 8-bit GIFs without interlacing
or transparency. More to come.
I'll put in more tests as the feature set grows.

This means that the -x flag can work, which could enable
support for other languages (e.g. objective-C).

The current iteration can decode 8-bit images in
grayscale, paletted, RGB, RGBA and NRGBA mode. LZW compression
is implemented but does not work on my test images.
Deflate (i.e. zlib) compression with or without a horizontal
predictor is supported.

On my laptop, I had an 800x600 jpeg and an 800x600 png (with
transparency). I timed how long it took to draw each image onto an
equivalently sized, zeroed RGBA image.
Previously, the jpeg took 75ms and the png took 70ms, going through
the medium-fast path, i.e. func drawRGBA in draw.go.
After this CL, the jpeg took 14ms, and the png took 21ms with the
Over operator and 12ms with the Src operator.
It's only a rough estimate basd on one image file, but it should
give an idea of the order of magnitude of improvement.

Note that if you are working on the upcoming release
branch you have to point your extension path to a
copy of lib/codereview/codereview.py that won't change
as the repository flips between release-branch and default branch.
This warning should only apply to this one branch and only to rsc,
but you never know.
