Use this for headers whose values are *not* comma-delimited lists, and which
therefore can only appear at most once in the headers. For list-valued
headers, use soup.message_headers.MessageHeaders.getList.
If hdrs does erroneously contain multiple copies of the header, it
is not defined which one will be returned. (Ideally, it will return
whichever one makes libsoup most compatible with other HTTP
implementations.)
