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.

Verified the change (on a fast machine) by removing the
existing sleep, in which case the race happens ~50% of the
time with GOMAXPROCS > 1, but recovers gracefully with
retries.

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.

This was seen breaking the slow arm5 builder:

The new gotest ignores Test functions outside *_test.go files
(the old shell script allowed them), so replace one clumsy hack
with another.

The root problem is that the package makefiles only know
how to run cgo for source files in the package proper, not
for test files.  Making it work for test files is probably more
trouble than it's worth.

- added a cache for last file looked up: avoids binary
  search if the file matches

- don't look up extra line info if not present
  (it is almost never present)

- inline one critical binary search call (inlining
  provides almost 30% improvement in this case)

Together, these changes make the go/printer benchmark
more than twice as fast (53% improvement). gofmt also
sped up by about the same amount.

Also: removed an unused internal field from FileSet.

Measurements (always best of 5 runs):

* original:
  printer.BenchmarkPrint     5    238354200 ns/op (100%)

* using last file cache:

* avoiding lookup of extra line info:
  printer.BenchmarkPrint    10    157072700 ns/op (66%)

* inlining a critical binary search call:
