Use error_fatal to simplify obvious fatal errors

Done with this Coccinelle semantic patch:

    @@
    type T;
    identifier FUN, RET;
    expression list ARGS;
    expression ERR, EC;
    @@
    (
    -    T RET = FUN(ARGS, &ERR);
    +    T RET = FUN(ARGS, &error_fatal);
    |
    -    RET = FUN(ARGS, &ERR);
    +    RET = FUN(ARGS, &error_fatal);
    |
    -    FUN(ARGS, &ERR);
    +    FUN(ARGS, &error_fatal);
    )
    -    if (ERR != NULL) {
    -        error_report_err(ERR);
    -        exit(EC);
    -    }

This is actually a more elegant version of my initial semantic patch
by courtesy of Eduardo.

It leaves dead Error * variables behind, cleaned up manually.
