Otherwise concurrently running threads may inadvertently use the same
token for different messages.
Preserve the behaviour of disallowing negative message tokens, but allow
a message token value of zero since this simplifies the code a bit and
tokens are documented to be non-negative.

userland can reply to a message with NGM_HASREPLY bit set. In this case

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.

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().

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.

NGM_BINARY2ASCII, which convert control messages to ASCII and back.
This allows control messages to be sent and received in ASCII form
using ngctl(8), which makes ngctl a lot more useful.
This also allows all the type-specific debugging code in libnetgraph
to go away -- instead, we just ask the node itself to do the ASCII
translation for us.
Currently, all generic control messages are supported, as well as
messages associated with the following node types: async, cisco,
ksocket, and ppp.
See /usr/share/examples/netgraph/ngctl for an example of using this.
Also give ngctl(8) the ability to print out incoming data and
control messages at any time. Eventually nghook(8) may be subsumed.
Several other misc. bug fixes.
