Use _LIBNFTABLES_ prefix to avoid possible clash with headers that
are defined in other libraries that may be used by third party
applications.

The headers do not compile standalone which may cause compilation
problems to third party programs.

The nft limit match currently does not work at all. Below patches to
nftables, libnftables, and kernel address the issue. A few notes on
the implementation:
- Removed support for nano/micro/milli second limits. These seem pointless,
given we are using jiffies in the limit match, not a hpet. And who really
needs to limit items down to sub-second level??
- 'depth' member is removed as unnecessary. All we need in the kernel is the
rate and the unit.
- 'stamp' member becomes the time we need to next refresh the token bucket,
instead of being updated on every packet which goes through the match.
This closes netfilter bugzilla #827, reported by Eric Leblond.

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.

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.
