This machinery was introduced to avoid sudden compilation breakage of
old nftables releases. With the upcoming release of 0.7 (and 0.6 which
is now 6 months old) this is not required anymore. Moreover, users gain
nothing from older releases since they are half-boiled and buggy.
So let's get rid of aliases now. Bump LIBVERSION and update map file.

flow table support needs constant object arguments to printing functions
to avoid ugly casts. While at it, also constify object arguments to message
construction, destructor and a few helper functions.

The function names are already large, trim off the _ATTR_ infix in the
attribute definitions.

This patch restores the original nft_* definitions from the header files to
avoid sudden compilation breakage of the existing clients of this library.
Then, moving forward the idea is to deprecate the old nft_* symbols anytime
soon using __attribute__((deprecated)) from the header files to warn our users
that they need to update their code.

So we can use the nft_* prefix anytime soon for our upcoming higher level
library.
After this patch, the nft_* symbols become an alias of the nftnl_* symbols.

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.

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

We plan to use this library name for the higher layer library.
