Without quotes, $@ loses its special meanining (see below)
% sh -c 'echo $@' /bin/sh " 1 " " 2 "
1 2
% sh -c 'echo "$@"' /bin/sh " 1 " " 2 "
1 2
The quotes are required to get ARGV to be unperterped
now maintained in a single linked-list in a transport-independent manner.
- Use queue.h for linked-list structure.
- Use linked-list for AllowedPeers.
- Use getaddrinfo(8) even for Unix Domain sockets.
- Use macros to type-casting from/to struct sockaddr{,_in,_in6}.
- Define fu_* macro for union f_un to shorten the member names.
- Remove an extra #include <sys/type.h>.
- Add "static" to non-exported symbols.
- !INET support is still incomplete but will be fixed later.
There is no functional change except for some minor debug messages.

server.
This patch uses the sysctl vfs.nfsd.server_min_nfsvers to determine
if/what versions of NFS service should be registered with rpcbind.
For NFSv4 only, it does not register at all, since NFSv4 always uses 2049
and does not require rpcbind.
For NFSv3 minimum, it registers NFSv3 but not NFSv2.

The TCP server implementation in dbgport does not track clients, so it
may try to write to a disconected socket resulting in SIGPIPE.
Avoid that by setting SO_NOSIGPIPE socket option.
Because dbgport emulates an I/O port to guest, the communication is done
byte by byte. Reduce latency of the TCP/IP transfers by using
TCP_NODELAY option. In my tests that change improves performance of
kgdb commands with lots of output (e.g. info threads) by two orders of
magnitude.
A general note. Since we have a uart emulation in bhyve, that can be
used for the console and gdb access to guests. So, bvmconsole and bvmdebug
could be de-orbited now. But there are many existing deployments that
still dependend on those.
