Increased maximum read PROXY protocol header size. Maximum size for reading the PROXY protocol header is increased to 4096 to accommodate a bigger number of TLVs, which are supported since cca4c8a715de. Maximum size for writing the PROXY protocol header is not changed since only version 1 is currently supported.
