[PATCH v3 10/10] vcs-svn: add fast_export_note to create notes

[Dmitry Ivankov <divanorama@gmail.com>]

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)
