This removes the last parameter of recv_sideband, by which the callers
told which channel bands #2 and #3 should be written to.

Sayeth Shawn Pearce:

   The definition of the streams in the current sideband protocol
   are rather well defined for the one protocol that uses it,
   fetch-pack/receive-pack:

     stream #1:  pack data
     stream #2:  stderr messages, progress, meant for tty
     stream #3:  abort message, remote is dead, goodbye!

Since both callers of the function passed 2 for the parameter, we hereby
remove it and send bands #2 and #3 to stderr explicitly using fprintf.

This has the nice side-effect that these two streams pass through our
ANSI emulation layer on Windows.
