We remove mnl_align() since it has been replaced by the macro
MNL_ALIGN(). The macro allows its use in static arrays and
such.

This patch changes the callback handlers to include netlink portID
checking. Thus, we avoid that any malicious process can spoof
messages.
If portid, sequence number of the message is != 0, we check if the
message is what we expect. This allows to use the same netlink channel
for dumps (portid, seq != 0) and event-based notifications (portid, seq == 0).

This patch may contain errors but we can review them and fix them later,
better to have it in the tree (to allow others to contribute) to keep it
in my local tree.
