43331419f6 MJPEGServer: Output boundary at start of image instead of end. 
This avoids hiccups/timeouts causing the next image being seen as a
completely new file rather than a continuation of a multi-part.

052f746c68 Use StringRef and ArrayRef return values when buf passed. 
For functions where a SmallVector is passed to be used as a stack buffer for
the return value, have the return value be the appropriate StringRef or
ArrayRef type.  This allows for both more natural usage and enables directly
returning (rather than copying) a permanently stored or constant string.
