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 a new API to parse rule-set expressed in XML/JSON from
a file. A new enum nft_parse_input type is added for this purpose.

The intention behind this patch is to prepare the introduction of
the new API that will allow us to parse files that contain the rule-sets
expressed in XML/JSON format. This adds the NFT_PARSE_BUFFER that
indicates that the input is provided in a buffer, which is what we
currently support.

Add missing support in the API function to parse a JSON set_elem.
I've renamed the main JSON parsing function to prevent clashing.

I have added a new structure for reporting some errors in parser
that we can't cover with errno.
In this patch, we have three errors that we can't cover with errno:
NFT_PARSE_EBADINPUT : Bad XML/JSON format in the input
NFT_PARSE_EMISSINGNODE : Missing node in our input
NFT_PARSE_EBADTYPE : Wrong type value in a node

This patch is a cleanup to save LOC.
I have also changed it to use < 0 to check for error conditions.

This patch fixes some leaks in the json parsing function. After this patch,
we use nft_jansson_free_root. This function uses json_decref and it
decrements the reference count and it releases the node if needed.

Instead of returning ERANGE all the time, let functions set
errno accordingly and set EINVAL otherwise.
