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.

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 breaks the ABI to shrink the size parameter from 8
to 4 bytes in x86_64. The maximum length of netlink attributes
is 2 bytes, so 4 bytes as attribute payload length should be
enough.
After this patch, size_t is only used in the nft_*_snprintf
interfaces.

We have several char * field that were not constify to avoid
gcc compilation warnings when calling free. Since (99d2574 src:
add xfree and use it), we can fully constify these objects
fields without trouble.

Since (d844fa0 src: consolidate XML parsing of expressions via
nft_mxml_expr_parse), the library was not compiling with XML support
anymore.

Move common code for XML parsing of expressions to the new
nft_mxml_expr_parse function.
This patch reduces the XML parsing code in 300 LOC.

This patch adds capabilities for parsing a XML table/chain/rule.
Some comments:
* The XML data is case sensitive
(so <chain>asd</chain> != <chain>ASD</chain> != <CHAIN>asd</CHAIN>)
* All exported functions receive XML and return an object (table|chain|rule).
* To compile the lib with XML parsing support, run './configure --with-xml-parsing'
* XML parsing is done with libmxml (http://minixml.org). XML parsing depends
on this external lib, this dependency is optional at compile time.
NOTE: expr/target and expr/match binary data are exported.
[ Fixed to compile without --with-xml-parsing --pablo ]

Propagate the type and flags parameter to the expressions, so we can
implement outputs in different formats.

It adds support for table, chain and rule handling.
This also includes expression handling for each rule.
