Add all well-known headers to the perfect hash lookup table This expands the perfect hash lookup table to be able to match any entry in the list of well-known headers from tbl/http_headers.h.
Previously only the headers that had a non-zero filter flag section was kept in the fast match table.

hpack: fix pseudo-headers handling We should apply the same restrictions on the list of allowed characters inside H/2 pseudo-headers as we do for H/1. This error is translated into the headers we send to a backend over H/1.
Failure to do so could permit various exploits against a backend not handling malformed H/1 requests.
