The info area that this gets via the setter should be already
aligned. The caller has to care of this.

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.

It changes the parse and the snprint functions to omit unset values.
Also, It fixes an unnecessary comma after key-value pair type.
This comma is not necessary if there is not more key-value pairs in this expr.
Example:
"expr":[{"type":"log"}]
If It uses this rule:
nft add rule ip test output log
It gets this json file:
[...]
{"expr":[{"type":"log","prefix":"(null)","group":0,"snaplen":0,"qthreshold":0}]}
[...]
Now, That rule creates this json file without null values:
{"expr":[{"type":"log"}]}

If we used this rule:
nft add rule ip test output log
We got this xml file:
<rule><family>ip</family>
<table>test</table>
<chain>output</chain>
<handle>88</handle>
<expr type="log">
<prefix>(null)</prefix>
<group>0</group>
<snaplen>0</snaplen>
<qthreshold>0</qthreshold>
</expr>
</rule>
And It was imposible import this file.
Now, That rule creates this xml file without null values:
<rule><family>ip</family>
<table>test</table>
<chain>output</chain>
<handle>88</handle>
<expr type="log">
</expr>
</rule>
and It's possible import this xml file.

Patrick reports that the XML/JSON formats of the data_reg object
are not accuarate.
This patch updates these formats, so they are now as follow:
* <data_reg type=value> with raw data (this doesn't change).
* <data_reg type=verdict> with a concrete verdict (eg drop accept) and an
optional <chain>, with destination.
In XML:
<data_reg type="verdict">
<verdict>goto</verdict>
<chain>output</chain>
</data_reg>
In JSON:
"data_reg" : {
"type" : "verdict",
"verdict" : "goto"
"chain" : "output",
}
The default output format is updated to reflect these changes (minor collateral
thing).
When parsing set_elems, to know if we need to add the NFT_SET_ELEM_ATTR_CHAIN
flag, a basic check for the chain not being NULL is done, instead of evaluating
if the result of the parsing was DATA_CHAIN. The DATA_CHAIN symbol is no longer
used in the data_reg XML/JSON parsing zone.
While at it, I updated the error reporting stuff regarding data_reg/verdict, in
order to leave a consistent state in the library.
A JSON testfile is updated as well.

Some verdicts have a negative value.
The caller of nft_str2verdict() checking if return was < 0 clash with
enum nft_verdict.
While at it, add error reporting of invalid verdicts.

The 'dir' attribute is optional as stated in the kernel sources.
Previous to this patch, using XML/JSON to manage this expr produces some
undefined and erroneous behaviours.

Due to missing NFT_CT_L3PROTOCOL key in ctkey2str_array, a segfault is
produced when the str2ctkey() loop reaches that position, since strcmp()
will try to compare a NULL value.
