Use a shorter name for this, morever this can be used from sets so the _rule_
is misleading.

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.

We cannot use __attribute__((constructor)) to register the supported
expressions in runtime when the library is statically linked. This lead
us to some explicit libnftnl_init() function that needs to be called
from the main() function of the client program.
This patch reverts 4dd0772 ("expr: use __attribute__((constructor)) to
register expression").

The internal.h file started being a small file with private definitions.
Its size has been increasing over time more and more, so let's split
this in small header files that map to the corresponding class where the
functions belong to.

Add new buffer class to consolidate the existing code to export objects
in XML/JSON and use it. We save ~700 LOC with this change.
The rule and set objects are not yet consolidated. It seems this would
require some specific glue code per representation type since lists are
arranged differently.
This also consolidates the tag names, so we make sure the same are used
from XML and JSON by placing them in include/buffer.h.

If the kernel sends us different data length for a given attribute,
stop further processing and indicate that an ABI breakage has ocurred.
This is an example of the (hypothetical) message that is shown in that
case:
nf_tables kernel ABI is broken, contact your vendor.
table.c:214 reason: Numerical result out of range

Code refactoring to use snprintf and SNPRINTF_BUFFER_SIZE in
snprintf_default functions. Also, It adapts to the next syntax in queue.
Added in:
http://git.netfilter.org/nftables/commit/?id=27619ffbe503ed4d9e59a02e81db9a7ac49d37af
Here, some examples:
ip test input 31
[ queue num 3-5 bypass fanout]
ip test input 32 31
[ queue num 0]
ip test input 33 32
[ queue num 4]
ip test input 34 33
[ queue num 2-6 bypass]
table ip test {
chain input {
type filter hook input priority 0;
queue num 3-5 bypass fanout
queue num 0
queue num 4
queue num 2-6 bypass
}

It changes the parse and the snprint functions to omit unset values.
This json file is gotten for a queue:
{"expr":[{"type":"queue","num":0,"total":1,"flags":0}]}

Code refactoring in nft_rule_expr_queue_snprinf functions. This patch
adds three new functions:
* nft_rule_expr_queue_snprinf_default
* nft_rule_expr_queue_snprinf_xml
* nft_rule_expr_queue_snprinf_json
Moreover, I have deleted an unnecesary whitespace as the CodingStyle
recommends.
