      Ignore CRLF (or LF) when PEEK'ing at data on the socket. The general · de9c9a7c
      Ryan Bloom authored 
      problem is that some browsers send an extra line at the end of a POST
request.  We use the PEEK method to determine if there is any data left
on the socket, if there is then we delay sending the response until we
have enough data to make it worthwhile.  If the browser sends an extra
blank line, we don't want to delay the response at all.  The only time
we use the PEEK method is to check for a second request, so this is safe
to do.

This also solves Joe Orton's problem of specifying a Content- Length
of 1 for a blank line, and having the server wait to send back a response.
The problem is that Linux (all Unix really) sends two characters \r\n for
a blank line, so specifying a C-L of 1 means that the server still sees
a \n when it PEEKs that the socket data.  That \n can be safely ignored
however.
