The http.Transport's retry can't retry requests with non-nil bodies. When cloning an incoming server request into an outgoing client request, nil out the Body field if the ContentLength is 0. (For server requests, Body is always non-nil, even for GET, HEAD, etc.) Also, don't use the deprecated CancelRequest and use Context instead. And don't set Proto, ProtoMajor, ProtoMinor. Those are ignored in client requests, which was probably a later documentation clarification.

The maximum input plaintext for GCM is 64GiB - 64. Since the GCM interface is one-shot, it's very hard to hit this in Go (one would need a 64GiB buffer in memory), but we should still enforce this limit. Thanks to Quan Nguyen for pointing it out.

In Go 1.0, the Config struct consisted only of exported fields. In Go 1.1, it started to grow private, uncopyable fields (sync.Once, sync.Mutex, etc). Ever since, people have been writing their own private Config.Clone methods, or risking it and doing a language-level shallow copy and copying the unexported sync variables. Clean this up and export the Config.clone method as Config.Clone. This matches the convention of Template.Clone from text/template and html/template at least.

The tar.Reader guarantees stickiness of errors. Ensuring this property means that the methods of Reader need to be consistent about whose responsibility it is to actually ensure that errors are sticky. In this CL, we make it only the responsibility of the exported methods (Next and Read) to store tr.err. All other methods just return the error as is. As part of this change, we also check the error value of mergePAX (and test that it properly detects invalid PAX files). Since the value of mergePAX was never used before, we change it such that it always returns ErrHeader instead of strconv.SyntaxError. This keeps it consistent with other usages of strconv in the same tar package.

Instead of saving all pragmas and processing them after parsing is finished, process them immediately during scanning like the current lexer does. This is a bit unfortunate because it means we can't use syntax.ParseFile to concurrently parse files yet, but it fixes how we report syntax errors in the presence of //line pragmas. While here, add a bunch more gcCompat entries to syntax/parser.go to get "go build -toolexec='toolstash -cmp' std cmd" passing. There are still a few remaining cases only triggered building unit tests, but this seems like a nice checkpoint.
