Load QUIC build config in spdy/core/hpack/BUILD, spdy/platform/api/BUILD and spdy/platform/impl/BUILD. This CL helps align the google3 spdy core build with Chromium, which prevents quiche merge issues. All non-trivial changes are found by enabling this build config: unused parameters, inconsistent param names between .h and .cc files. gfe-relnote: n/a, build-only change.
