This function releases the ruleset objects attached in the parse context
structure, ie. struct nft_parse_ctx.
Moreover, this patch updates the nft_parse_ruleset_file to use it.

This patch adds support to parse the new command tag in XML/JSON. This
patch adds two new functions:
* nft_ruleset_parse_file_cb
* nft_ruleset_parse_buffer_cb
The idea is to invoke the callback function that is passed as parameter is
called for each object that is parsed from the corresponding input. Each
callback has access to the nft_parse_ctx structure that provides the necessary
context such as the command, the object type and the object itself.
This change also adds support to update the content of a set incrementally.
{"nftables":[{"add":[{"element":{"name":"blackhole","table":"filter",
"family":"ip","key_type":7,"key_len":4,"set_elem":[{"key":{
"reg":{"type":"value","len":4,"data0":"0x0403a8c0"}}}]}}]}]}
This also patch consolidates the xml/json ruleset import path.

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.

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.
