io: add ReadAtSizer interface

ReadAtSizer is a common abstraction for a stateless,
concurrently-readable fixed number of bytes.

This interface has existed in various codebases for over 3 years (previously
usually named SizeReaderAt). It is used inside Google in dl.google.com
(mentioned in https://talks.golang.org/2013/oscon-dl.slide) and other
packages. It is used in Camlistore, in Juju, in the Google API Go client, in
github.com/nightlyone/views, and 33 other pages of Github search results.

It is implemented by io.SectionReader, bytes.Reader, strings.Reader, etc.

Time to finally promote this interface to the standard library and give it a
standard name, blessing it as best practice.

The Go Programming Language

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

For documentation about how to install and use Go, visit https://golang.org/ or load doc/install-source.html in your web browser.

Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.

Go is the work of hundreds of contributors. We appreciate your help!

To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html

Note that we do not accept pull requests and that we use the issue tracker for bug reports and proposals only. Please ask questions on https://forum.golangbridge.org or https://groups.google.com/forum/#!forum/golang-nuts.

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin

See https://golang.org/doc/install or doc/install.html for more details.
