Small fix: looks like a short variable declaration with a type switch
checks to make sure the variable used had valid shape (ONAME, OTYPE, or
ONONAME) and rejects everything else. Then a new variable is declared.
If the symbol contained in the declaration was a named OLITERAL (still a
valid identifier obviously) it would be rejected, even though a new
variable would have been declared.
Fix adds this case to the check.
Added a test case from issue12413.

In https://golang.org/cl/15860 http2.ConfigureServer was changed to
return an error if explicit CipherSuites are listed and they're not

This is the net/http side of the change, to look at the return value
from ConfigureServer and propagate it in Server.Serve.
h2_bundle.go will be updated in a future CL. There are too many other
http2 changes pending to be worth updating it now. Instead,
h2_bundle.go is minimally updated by hand in this CL so at least the

The spec defines precise numeric constants which do not overflow.
Consequently, +/-Inf and NaN values were excluded. The case was not
clear for -0.0 but they are mostly of interest to determine the sign
of infinities which don't exist.
That said, the conversion rules explicitly say that T(x) (for a numeric
x and floating-point type T) is the value after rounding per IEEE-754.
The result is constant if x is constant. Rounding per IEEE-754 can
produce a -0.0 which we cannot represent as a constant.
Thus, the spec is inconsistent. Attempt to fix the inconsistency by
adjusting the rounding rule rather than letting -0.0 into the language.
For more details, see the issue below.
Open to discussion.

For printing, the format verb '%X' results in a capitalized

'%X' in a Scanf function should scan a hex-representation
into the given interface{}. The existing implementation
however only supports '%X' for scanning hex values into

fine. This is merely an oversight, which this commit fixes.

This is the start of wiring up the HTTP/2 Transport. It is still
disabled in this commit.
This change does two main things:
1) Transport.RegisterProtocol now permits registering "http" or
"https" (they previously paniced), and the semantics of the
registered RoundTripper have been extended to say that the new
sentinel error value (ErrSkipAltProtocol, added in this CL) means
that the Transport's RoundTrip method proceeds as if the alternate
protocol had not been registered. This gives us a place to register
an alternate "https" RoundTripper which gets first dibs on using
HTTP/2 if there's already a cached connection.
2) adds Transport.TLSNextProto, a map keyed by TLS NPN/ALPN protocol
strings, similar in feel to the existing Server.TLSNextProto map.
This map is the glue between the HTTP/1 and HTTP/2 clients, since
we don't know which protocol we're going to speak (and thus which
Transport type to use) until we've already made the TCP connection.

The flate library guarantees that the Reader will never read more
bytes than is necessary. This way, the underlying io.Reader will
be left exactly after the last byte of the DEFLATE stream.
Formats like gzip depend on this behavior being true.
As such, inflate conservatively reads the minimum symbol length in
huffSym leading to many individual calls to moreBits. However, if we
take advantage of the fact that every block *must* end with the EOB
symbol, we can choose to read the length of the EOB symbol.
Since the EOB symbol is also the most rare symbol (occuring exactly
once) in a block, we can hypothesize that it is almost as long as
the max symbol length, allowing huffSym to ask for more bits at the
start of every loop. This increases the probabilty that the Huffman
code is decoded on the first iteration of the outer for-loop.
