net/http: avoid quadratic complexity in HPACK decoding
A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of small requests.
This issue is also fixed in golang.org/x/net/http2 v0.7.0, for users manually configuring HTTP/2.
Thanks to Philippe Antoine (Catena cyber) for reporting this issue.
