Brad Fitzpatrick 22bb95c5e7 http2/hpack: lazily build huffman table on first use
This generated 120 kB on the heap before at init, regardless of
whether somebody used http2. Worse, because we vendored it into std,
users would have two copies, for about 256 kB of memory. After CL
127235 that went down to 60 kB per copy, so 120 kB for a binary using
golang.org/x/net/http2 explicitly.

With this, it goes to 0 until one of the two copies in the binary
actually uses one of the http2 packages.

I wasn't able to measure any difference with the Once.Do in the decode
path:

name             old time/op    new time/op    delta
HuffmanDecode-4     732ns ± 8%     707ns ± 3%   ~            (p=0.268 n=10+9)

(admittedly noisy)
