Improve multipart HTTP/MIME entity file analysis.

Browse source 
Singular CR or LF characters in multipart body content are no longer
converted to a full CRLF (thus corrupting the file) and it also no
longer considers the CRLF before the multipart boundary as part of the
content.

Addresses BIT-1235.
