notes.c: introduce '--separator=<paragraph-break>' option

When adding new notes or appending to an existing notes, we will
insert a blank line between the paragraphs, like:

     $ git notes add -m foo -m bar
     $ git notes show HEAD
     foo

     bar

The default behavour sometimes is not enough, the user may want
to use a custom delimiter between paragraphs, like when
specifying '-m', '-F', '-C', '-c' options. So this commit
introduce a new '--separator' option for 'git notes add' and
'git notes append', for example when executing:

    $ git notes add -m foo -m bar --separator="-"
    $ git notes show HEAD
    foo
    -
    bar

a newline is added to the value given to --separator if it
does not end with one already. So when executing:

      $ git notes add -m foo -m bar --separator="-"
and
      $ export LF="
      "
      $ git notes add -m foo -m bar --separator="-$LF"

Both the two exections produce the same result.

The reason we use a "strbuf" array to concat but not "string_list", is
that the binary file content may contain '\0' in the middle, this will
cause the corrupt result if using a string to save.
