Remove $FreeBSD$: two-line nroff pattern

Remove /^\.\\"\n\.\\"\s*\$FreeBSD\$$\n/

Fix SYNPOSIS section to point to the proper include directive.

netgraph(3) points to #include <netgraph/netgraph.h>, which is kernel only.
The man page refers to the user-space part of the netgraph module, which is
located in <netgraph.h>.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.

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.

Mechanically kill hard sentence breaks.

- 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().

mdoc(7) cleanup.

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.

Rename the DIAGNOSTICS section to RETURN VALUES and describe the
return values a little more. Specifically, mention that a return
of 0 from NgRecvData() and NgRecvMsg() means the socket has been
closed.

Suggested by: jkh

Explain what the return value from NgRecvMsg() and NgRecvData() means,
specifically that 0 means the socket has been closed.

Remove whitespace at EOL.

mdoc(7) police: removed HISTORY info from the .Os call.

mdoc(7) police: sort SEE ALSO xrefs (sort -b -f +2 -3 +1 -2).

Correct cross-references:
ng_bpf.8 --> ng_bpf.4
ng_ether.8 --> ng_ether.4
ng_iface.8 --> ng_iface.4
ng_pppoe.8 --> ng_pppoe.4
ng_socket.8 --> ng_socket.4
ng_tty.8 --> ng_tty.4
ng_{type}.4 --> /dev/null

- Make sure the message token returned by NgSendMsg() is non-negative
- Have NgSendAsciiMsg() return the same token as NgSendMsg()
- Document that NgSendMsg() and NgSendAsciiMsg() return the token
- Add MLINKS for the functions defined in netgraph(3)

Move netgraph node type man pages from section 8 to section 4.

Introduce .Lb macro to netgraph library manpage

Have NgMkSockNode() load the socket node type KLD if it's not

thanks!

Add two new generic control messages, NGM_ASCII2BINARY and
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.
