These functions make assumptions on size of passed data pointer and
therefore tend to hide programming mistakes. Instead either one of the
type-specific setters or the generic *_set_data() setter should be used.

These functions are not very useful, rule comparison from this layer
does not work well with implicit set definitions.
This infrastructure was added as an attempt to support for deletion by
name from this layer, which should be done from higher level libnftables
library. Finally, we never had a client for this code in
git.netfilter.org.
Let's remove it and bump libversion for safety reasons.

This machinery was introduced to avoid sudden compilation breakage of
old nftables releases. With the upcoming release of 0.7 (and 0.6 which
is now 6 months old) this is not required anymore. Moreover, users gain
nothing from older releases since they are half-boiled and buggy.
So let's get rid of aliases now. Bump LIBVERSION and update map file.

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.

Iterators do not modify objects which they iterate, so input pointer must
be const.

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.

The function names are already large, trim off the _ATTR_ infix in the
attribute definitions.

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.

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.

This allows us to remove the default case in the switch, which
show help to spot missing attribute support since gcc will spot
a compilation warning.
