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.

Add the use of system errors (nft_parse_perror) in test_xml to know which
node is not found.
Example:
parsing xmlfiles/75-ruleset.xml: FAILED (Invalid argument)
Reason : Node "flags" not found
[ I have mangled this patch to rename this the current 'fail' message
to 'Reason' --pablo ]

Free nft_parse_err struct when there is an error in execute_test function.
It solves the following memory leak shown by valgrind.
==7845== 24 bytes in 1 blocks are still reachable in loss record 1 of 2

New tools to updata testfiles when the structure of xml or json files
are changed.
It adds a new command-line argument in nft-parsing-test.
With nft-parsing-test -u <directory>, you can update test files in
<directory> with a new structure of xml or json 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.

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

Unify parse and output types that are redundant to all
existing nftables objects. Thus, all NFT_*_O_[XML|JSON|DEFAULT]
are merged into NFT_OUTPUT_[JSON|XML] and NFT_PARSE_[JSON|XML].

Before this patch, the test only verified that we could parse
the file. After this, it also compares what it has parsed with
the original file.
Basically, the idea is that:
file -> buffer -> object -> buffer'
read snprintf
So we also compare that buffer = buffer' which should be true
since our tests should be based on the output that the library
generates.
This is an example output for the OK and FAILED cases:
parsing and validating xmlfiles/25-rule-exthdr.xml: OK
validating xmlfiles/27-rule-limit.xml: FAILED
from file: it"><rate>123123</ra
from snprintf: it"><rate>321321</ra

This patch add a testbench for XML parsing, which may be extended
to test JSON as well.
To use it:
$ cd test/
$ make nft-parsing-test
$ ./nft-parsing-test xmlfiles/
This testbench supersedes old .sh test scripts, so they are deleted.
[ I have mangled this patch to rename/mangle files, to colorize the
test output and not to compile XML inconditionally --pablo ]
