15e6f8c02a Fix for quite a special case when userland emulates a netgraph node, and 
userland can reply to a message with NGM_HASREPLY bit set. In this case
we should not wait for a response to a responce.

b41c473d90 bring the NGM_IPFW_COOKIE back into ng_ipfw.h, libnetgraph expects 
to find it there. Unfortunately this reintroduces the dependency
on ip_fw_pfil.c

a8f06e9570 In the splnet(9) times netgraph(4) was synchronous and if a message 
had been replied, the reply was always delivered to the originator
synchronously.

With introduction of netgraph item callbacks and a wait channel with
mutex in ng_socket(4), we have fixed the problem with ngctl(8) returning
earlier than the command has been proceeded by target node. But still
ngctl(8) can return prior to the reply has arrived to its node.

To fix this:
 - Introduce a new flag for netgraph(4) messages - NGM_HASREPLY.
   This flag is or'ed with message like NGM_READONLY.
 - In netgraph userland library if we have sent a message with
   NGM_HASREPLY flag, then select(2) until reply comes.
 - Mark appropriate generic commands with NGM_HASREPLY flag,
   gathering them into one enum {}. Bump generic cookie.

7c4554894b Yes, NgRecvAsciiMsg has the same results as NgRecvAsciiMsg, but it's 
much more apt to note that it has the same result as NgRecvMsg.  Make
the manual page less circular in its reference to this fact.

adc82a1e80 - Added three new interfaces, NgAllocRecvMsg(), NgAllocRecvAsciiMsg(), 
and NgAllocRecvData(), that dynamically allocate buffer for a binary
  message, an ascii message, and a data packet, respectively.  The size
  of the allocated buffer is equal to the socket's receive buffer size
  to guarantee that a message or a data packet is not truncated.

- Get rid of the static size buffer in NgSendAsciiMsg().

5afef437ec Use the new defines that include the trailing '\0' in the code. 
Replace occurences of the magic constant 2 with an offsetof macro
call that computes the size of the leading members of the sockaddr.
Use strlcpy instead of sprintf where appropriate. Document the new changes
in the man page.
