It deletes the immediatedata label in the structure of json and xml file.
Example of the old structure of xmlfile:
<nftables>
<rule>
<family>ip</family>
<table>filter</table>
<chain>input</chain>
<handle>32</handle>
<expr type="immediate">
<dreg>0</dreg>
<immediatedata>
<data_reg type="verdict">
<verdict>accept</verdict>
</data_reg>
</immediatedata>
</expr>
</rule>
</nftables>
Example of the new structure of xmlfile:
<nftables>
<rule>
<family>ip</family>
<table>filter</table>
<chain>input</chain>
<handle>32</handle>
<expr type="immediate">
<dreg>0</dreg>
<data_reg type="verdict">
<verdict>accept</verdict>
</data_reg>
</expr>
</rule>
</nftables>
To generate the new testfiles, It use the option -u of nft-parsing-test
script.

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.

This patch adds userspace support for the meta expression in the set flavour.
This expression indicates that the packet has to be set with a property,
currently one of mark, priority or nftrace.

Remove all the spaces from the JSON output to reduce the size
of the output string, this also provides a consistent output
in table, chain, rule and set.
As Stephen Hemminger suggested, better to squash the output to
consume as less bytes as possible.

This patch removes the version XML node and the version JSON field
in all our existing objects. The current versioning approach
consists of adding a version field to every object representation
in XML and JSON. While listing my entire rule-set, one can notice
that this approach is too bloated.
Once the library enters stable stage, if we need to obsolete a XML
node and a JSON field, we can follow this procedure:
1) Remove the XML node and the JSON field from the output, so fresh
outputs will not contain the old ones anymore.
2) Do not remove the parsing of the old XML node and the JSON field
inmediately. We have to keep supporting the parsing for a while
to avoid breaking the interpretion of old XML/JSON files. We can
spot a warning to warn about it, so users generate a fresh
output again.
