[LIBNL]: Fix nfnl_queue_msg_get_packetid() return type
The packet-ID is a 32 bit value, but nfnl_queue_msg_get_packetid() returns
an uint16_t. Makes queueing fail after 2^16 packets.

Split the nfnetlink_log code into two seperate objects, "netfilter/log"
to represent logging instances and "netfilter/log_msg" to represent
log messages. Also perform some function name unification for consistency
with other libnl object types, mainly renaming nfnl_log_build_*_msg
to nfnl_log_build_*_request.
This changes the API in an incompatible way, but since this feature is
new and the libnl netfilter headers haven't been installed so far,
there shouldn't be any users affected by this.

The NUFLA_GID attribute (currently only in net-2.6.25) contains the
gid of the sending process for locally generated packets.

The hwproto doesn't have its own attribute and is also present when
not set. Don't set the attribute if its value is zero.

vlan support needs VLAN_FLAG_REORDER_HDR, which is not available in
older if_vlan.h versions. Add the current version from the kernel.

Caches allocated by the cache manager must be freed again when the cache
manager itself is freed. However, the netlink socket is allocated
indepdently so it should not be freed.
Patrick McHardy reported a problem where pointers to the
payload of a netlink message as returned by f.e. the
nesting helpers become stale when the payload data
chunk is reallocated.
In order to avoid further problems, the payload chunk is
no longer extended on the fly. Instead the allocation is
made during netlink message object allocation time with
a default size of a page which should be fine for the
majority of all users. Additionally the functions
nlmsg_alloc_size() and nlmsg_set_default_size() have been
added to allocate messages of a particular length and to
modify the default message size.
So far the destination address for default routes was NULL
which complicated the handling of routes in general. By
assigning a address of length zero they can be compared
to each other.
This allows the cache manager to properly handle default
routes.
Fixes an off-by-one when releasing local ports. Fixes nl_connect()
to properly close the socket upon failure. Return EBADFD if
operations are performed on unconnected sockets where appropriate.
Makes nl_handle_alloc() return an error if all local ports are
used up.
