This patch implements the function:
bool nftnl_rule_cmp(const struct nftnl_rule *r1,
const struct nftnl_rule *r2)
for rule comparison.
Expressions within rules need to be compared, so also has been created the
function:
bool nftnl_expr_cmp(const struct nftnl_expr *e1,
const struct nftnl_expr *e2);
Also includes all expression comparators.

So the client can bail out of memory allocation errors. Or in case of
daemon, make sure things are left in consistent state before bailing
out.

flow table support needs constant object arguments to printing functions
to avoid ugly casts. While at it, also constify object arguments to message
construction, destructor and a few helper functions.

Use a shorter name for this, morever this can be used from sets so the _rule_
is misleading.

This patch restores the original nft_* definitions from the header files to
avoid sudden compilation breakage of the existing clients of this library.
Then, moving forward the idea is to deprecate the old nft_* symbols anytime
soon using __attribute__((deprecated)) from the header files to warn our users
that they need to update their code.

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.

The expression build function currently assumes to be only used from
rule context and actually builds rule attributes. Fix that and only
build the expression. Also it seems to have been exported by accident,
undo that.
Additionally, move the expression parsing function from rule parsing
and also remove any assumptions about being used in rule context.

This patch adds two functions that allows you to validate the size
of the attribute. This new functions provide a replacement for
nft_rule_attr_set and nft_rule_attr_get.
The data_len parameter was already passed to the {_set|_get} funcion
in expressions. For consistency, add nft_rule_expr_{set|get}_data
alias.
