[Libguestfs] [libnbd PATCH 4/6] state_machine_generator: wrap nbd_internal_enter_* prototypes

[Laszlo Ersek]

Similarly to commit bfef979aa372 ("generator: wrap "python/methods.h" at
80 characters", 2023-05-02), just break the fixed (and in itself, short)
parameter list to a new line.

Example effect in "lib/states.h":

> -extern int nbd_internal_enter_STATE_NEWSTYLE_OPT_STRUCTURED_REPLY_RECV_REPLY_PAYLOAD (struct nbd_handle *h, bool *blocked);
> +extern int nbd_internal_enter_STATE_NEWSTYLE_OPT_STRUCTURED_REPLY_RECV_REPLY_PAYLOAD (
> +             struct nbd_handle *h, bool *blocked
> +           );

Example effect in "lib/states.c":

> @@ -2566,9 +2626,11 @@ enter_STATE_NEWSTYLE_OPT_STRUCTURED_REPL

> +nbd_internal_enter_STATE_NEWSTYLE_OPT_STRUCTURED_REPLY_RECV_REPLY_PAYLOAD (

> +)
>  {
>    int r;
>    enum state next_state = STATE_NEWSTYLE_OPT_STRUCTURED_REPLY_RECV_REPLY_PAYLOAD;

Note that some of the modified lines remain longer than 80 characters, but
we'll live with that, as we don't want to change the "state_enum" field.
