Now, fdset_id is int64, but in some places we work with it as int.
It seems that there is no sense to use int64 for fdset_id, so it's
better to fix inconsistency by changing fdset_id type to int and by
fixing the reference of corresponding QMP commands: add-fd, remove-fd,
query-fdsets.

In C, you use int instead of int64_t for fdset IDs.

In the schema, you use QAPI type 'int32' instead of 'int'.

Before the patch, the two are consistent (except for the bugs you fixed
in v1 of this patch): QAPI 'int' is C int64_t.

After the patch, the two are inconsistent: QAPI 'int32' is C int32_t,
not int.  They're usually the same, but it unclean.

Two ways forward:

1. Revise this patch to use int32_t instead of int.

2. Revise v1 to address the few minor review comments I had.  Smaller
   patch, easier to review.

Your choice.  I'd choose 2.
