use camel_mkdir(0777) rather than 0777 & st.st_mode which isn't set

2004-01-21  Not Zed  <NotZed@Ximian.com>

        * em-migrate.c (cp_r): use camel_mkdir(0777) rather than 0777 &
        st.st_mode which isn't set anyway.
        (cp): use simple 0666 for the mode open, and then chmod after.
        (cp): check the return code of close, not just fsync.
        (cp): dont use fd[0] and fd[1] when we really just want simple
        variables, rename to readfd and writefd.
