Having this interface returning a const pointer makes very hard to
modificate the content of a chain contained in a nft_ruleset.

The generation object currently only contains the uint32_t that
indicates the generation ID. I could have just add the API to return
the uint32_t ID instead, but I think this API is easier to extend
without adding new APIs.
We can probably include meaningful statistics in the generation
message in the future without much hassle.
This patch also extends examples/nft-events.c.

This patch adds the following new interfaces:
int nft_batch_is_supported(void);
void nft_batch_begin(char *buf, uint32_t seq);
void nft_batch_end(char *buf, uint32_t seq);
Quite likely this is going to be reused by third party applications
requiring to put things in the batch. We already have potential clients
for this code in nft and iptables-compat.

This new interface allows you to put as many set elements as possible
into a netlink message. The iterator stores the last element that has
fit into a netlink message, so you can continue adding more set elements
across several netlink messages.

Add the set ID (u32) which allows us to uniquely identify the set
in the batch that is sent to kernel-space.

This patch uses the flag option of each output function to print an
event wrapper string in each object.
In order to use this functionality, the caller must pass the
corresponding flags: NFT_OF_EVENT_NEW / NFT_OF_EVENT_DEL.
(I have slightly refactorized the original code to add the xml/json
header and footer --pablo).

This patch adds two functions that allows you to validate the size
of the attribute. This new functions provide a replacement for
nft_rule_attr_set and nft_rule_attr_get.
The data_len parameter was already passed to the {_set|_get} funcion
in expressions. For consistency, add nft_rule_expr_{set|get}_data
alias.

This allows us to remove the default case in the switch, which
show help to spot missing attribute support since gcc will spot
a compilation warning.
