Some (mgmt) xlators: use dict_{setn|getn|deln|get_int32n|set_int32n|set_strn}

In a previous patch (https://review.gluster.org/20769) we've
added the key length to be passed to dict_* funcs, to remove the need
to strlen() it. This patch moves some xlators to use it.

- It also adds dict_get_int32n which was missing.
- It also reduces the size of some key variables.
They were set to 1024b or PATH_MAX, where sometimes 64 bytes were
really enough.

Please review carefully:
1. That I did not reduce some the size of the key variables too much.
2. That I did not mix up some keys.

Compile-tested only!
