…netty#9492) Motivation: `HttpObjectDecoder` pre-checks that it doesn't request characters outside of the `AppendableCharSequence`'s length. `0` is always allowed because the minimal length of `AppendableCharSequence` is `1`. We can legally skip index check by using `AppendableCharSequence.charAtUnsafe(int)` in all existing cases in `HttpObjectDecoder`. Modifications: - Use `AppendableCharSequence.charAtUnsafe(int)` instead of `AppendableCharSequence.charAt(int)` in `HttpObjectDecoder`. Result: No unnecessary index checks in `HttpObjectDecoder`. (cherry picked from commit 85fcf4e)
…30#section-3.2.4 (netty#9585) Motivation: When parsing HTTP headers special care needs to be taken when a whitespace is detected in the header name. Modifications: - Ignore whitespace when decoding response (just like before) - Throw exception when whitespace is detected during parsing - Add unit tests Result: Fixes netty#9571 (cherry picked from commit 39cafcb)
) Motivation: Technical speaking its valid to have http headers with no values so we should support it. That said we need to detect if these are "generated" because of an "invalid" fold. Modifications: - Detect if a colon is missing when parsing headers. - Add unit test Result: Fixes netty#9866 (cherry picked from commit a7c18d4)
…-length and transfer-encoding: chunked header when using HTTP/1.1 (netty#9865) Motivation: RFC7230 states that we should not accept multiple content-length headers and also should not accept a content-length header in combination with transfer-encoding: chunked Modifications: - Check for multiple content-length headers and if found mark message as invalid - Check if we found a content-length header and also a transfer-encoding: chunked and if so mark the message as invalid - Add unit test Result: Fixes netty#9861 (cherry picked from commit 8494b04)

This is similar to #20, except this PR skips the first two cherries in that one's sequence (already applied upstream between 4.1.25 and 4.1.34).
