[DCCP] ccid3: Reorder packet history header file
No code change at all. To make the header file easier to read, the following ordering is established among the declarations: * hist_new * hist_delete * hist_entry_new * hist_head * hist_find_entry * hist_add_entry * hist_entry_delete * hist_purge Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Acked-by: Ian McDonald <ian.mcdonald@jandi.co.nz> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
