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

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.
