While doing this, remove declarations from header files where the corresponding definition is declared "static" in order to avoid build errors. Also re-order existing headers in ui-*.c so that the file-specific header always comes immediately after "cgit.h", helping with future consistency. Signed-off-by: John Keeping <john@keeping.me.uk>
