Function read_request_with_deadlines 

pub fn read_request_with_deadlines<'a>(
    socket: &impl AsFd,
    storage: &'a mut [u8],
    policy: RequestPolicy,
    deadlines: RequestDeadlines,
) -> Result<Request<'a>>

Apply monotonic total-intake and idle-progress deadlines in addition to byte quotas and accepted-socket read timeouts. The deadline starts on this call, covers header/body intake and the final synchronous parse/inflation check, and never resets when a peer drips another byte. It excludes accept, Git preparation and response transmission. Close the socket on every error. Expired host deadlines return LimitExceeded; a shorter socket timeout retains Backend. Socket flags and timeout settings remain unchanged. With both deadlines unset this is identical to read_request_with_policy.
