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.

data_reg is unnecessarily long name and it always has to be
wrapped by another data node. This will allow us to represent
data not only as registers if needed.
Get rid of 'cmpdata' and 'immediatedata' too and use 'data'
instead to wrap 'reg' so these are consistent with the bitwise
expression. No reason for such specific tag per expression.

Add new buffer class to consolidate the existing code to export objects
in XML/JSON and use it. We save ~700 LOC with this change.
The rule and set objects are not yet consolidated. It seems this would
require some specific glue code per representation type since lists are
arranged differently.
This also consolidates the tag names, so we make sure the same are used
from XML and JSON by placing them in include/buffer.h.

Keeping the full cached copy the of x_tables.h file in tree is too much
for just the XT_EXTENSION_MAXNAMELEN constant. Similarly, xt_LOG.h is not
actually required by the tests, we can use any whatever syntetic data
to make sure the setter and getter provide the same result. So, let's
get rid of these headers from the library tree.

If the kernel sends us different data length for a given attribute,
stop further processing and indicate that an ABI breakage has ocurred.
This is an example of the (hypothetical) message that is shown in that
case:
nf_tables kernel ABI is broken, contact your vendor.
