Overwrite the X-Mozilla-Status header near the given file position.

Parameter Description
message_start The position in the file of the start of a message. A header block is assumed to start at this position. The file is scanned forward for an X-Mozilla-Status header in this block.
message_length The length of the message in bytes.
mozilla_flags The flags to overwrite into the existing X-Mozilla-Status header, if any.

Returns:
true if the header was overwritten, false otherwise.
