Track new sockets created during accept(2) in the socket table for all
families. Previously we were only doing this for unix domain sockets.

More helper structs have been added to the fsutil package to make it easier to

This option allows multiple sockets to be bound to the same port.
Incoming packets are distributed to sockets using a hash based on source and
destination addresses. This means that all packets from one sender will be
received by the same server socket.

FileOperations.Write should return ErrWouldBlock to allow the upper
layer to loop and sendmsg should continue writing where it left off
on a partial write.

With rpcinet if shutdown flags are not saved before making
the rpc a race is possible where blocked threads are woken
up before the flags have been persisted. This would mean
that threads can block indefinitely in a recvmsg after a
shutdown(SHUT_RD) has happened.

This change also adds extensive testing to the p9 package via mocks. The sanity
checks and type checks are moved from the gofer into the core package, where
they can be more easily validated.

Added events for *ctl syscalls that may have multiple different commands.
For runsc, each syscall event is only logged once. For *ctl syscalls, use
the cmd as identifier, not only the syscall number.

the stack Intefaces and InterfaceAddrs.
Also add some tests as we had no tests around SIOCGIFCONF. I also added the socket_netgofer lifecycle for IOCTL tests.

Correct a data race in rpcinet where a shutdown and recvmsg can
race around shutown flags.

Because rpcinet will emulate a blocking socket backed by an rpc based
non-blocking socket. In the event of a shutdown(SHUT_RD) followed by a
read a non-blocking socket is allowed to return an EWOULDBLOCK however
since a blocking socket knows it cannot receive anymore data it would
block indefinitely and in this situation linux returns 0. We have to
track this on the rpcinet sentry side so we can emulate that behavior
because the remote side has no way to know if the socket is actually
blocking within the sentry.

Rpcinet already inherits socket.ReceiveTimeout; however, it's
never set on setsockopt(2). The value is currently forwarded
as an RPC and ignored as all sockets will be non-blocking
on the RPC side.

SOCK_STREAM has special behavior with respect to MSG_TRUNC. Specifically,
the data isn't actually copied back out to userspace when MSG_TRUNC is
provided on a SOCK_STREAM.
According to tcp(7): "Since version 2.4, Linux supports the use of
MSG_TRUNC in the flags argument of recv(2) (and recvmsg(2)). This flag
causes the received bytes of data to be discarded, rather than passed
back in a caller-supplied buffer."

MSG_TRUNC can cause recvmsg(2) to return a value larger than
the buffer size. In this situation it's an indication that the
buffer was completely filled and that the msg was truncated.
Previously in rpcinet we were returning the buffer size but we
should actually be returning the payload length as returned by
the syscall.
