Revert "Reclaim one byte from HeaderString. (envoyproxy#6826)"
This is failing header_map_impl_fuzz due to memcpy heap buffer overflow and should be considered a serious security issue. Given this was only introduced in the last day and does not affect any release, a revert and bump is the consensus of Envoy security team. This reverts commit 977907d. Fixes oss-fuzz issue https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14639. Risk level: Low Testing: Corpus entry added, bazel test //test/common/http:header_map_impl_fuzz_test --test_output=all -c dbg --config=clang-asan Signed-off-by: Harvey Tuch <htuch@google.com>
