vcs-svn: add fast_export_note to create notes

Browse source 
fast_export lacked a method to writes notes to fast-import stream.
Add two new functions fast_export_note which is similar to
fast_export_modify. And also add fast_export_buf_to_data to be able to
write inline blobs that don't come from a line_buffer or from delta
application.

To be used like this:

  fast_export_begin_commit("refs/notes/somenotes", ...)
  fast_export_note("refs/heads/master", "inline")
  fast_export_buf_to_data(&data)

or maybe

  fast_export_note("refs/heads/master", sha1)
