- Check write permission on truncate(2). Unlike ftruncate(2),
truncate(2) fails if the user does not have write permissions
on the file.
- For gofers under InteropModeShared, check file type before
making a truncate request. We should fail early and avoid
making an rpc when possible. Furthermore, depending on the
remote host's failure may give us unexpected behavior--if the
host converts the truncate request to an ftruncate syscall on
an open fd, we will get EINVAL instead of EISDIR.
Updates #2923.

Changes the API of tcpip.Clock to also provide a method for scheduling and
rescheduling work after a specified duration. This change also implements the
AfterFunc method for existing implementations of tcpip.Clock.
This is the groundwork required to mock time within tests. All references to
CancellableTimer has been replaced with the tcpip.Job interface, allowing for
custom implementations of scheduling work.
This is a BREAKING CHANGE for clients that implement their own tcpip.Clock or
use tcpip.CancellableTimer. Migration plan:
1. Add AfterFunc(d, f) to tcpip.Clock
2. Replace references of tcpip.CancellableTimer with tcpip.Job
3. Replace calls to tcpip.CancellableTimer#StopLocked with tcpip.Job#Cancel
4. Replace calls to tcpip.CancellableTimer#Reset with tcpip.Job#Schedule
5. Replace calls to tcpip.NewCancellableTimer with tcpip.NewJob.

Like task_work in Linux, this allows us to register callbacks to be executed
before returning to userspace. This is needed for kcov support, which requires
coverage information to be up-to-date whenever we are in user mode. We will
provide coverage data through the kcov interface to enable coverage-directed
fuzzing in syzkaller.
One difference from Linux is that task work cannot queue work before the
transition to userspace that it precedes; queued work will be picked up before
the next transition.

Allow FUSE filesystems to be mounted using libfuse.
The appropriate flags and mount options are parsed and
understood by fusefs.

We were getting the file attributes before locking the metadataMu which was
causing stale updates to the file attributes.
Fixes OpenTest_AppendConcurrentWrite.

For iptables users, Check() is a hot path called for every packet one or more
times. Let's avoid a bunch of map lookups.

Helps in fixing open syscall tests: AppendConcurrentWrite and AppendOnly.
We also now update the file size for seekable special files (regular files)
which we were not doing earlier.

Now it calls pkt.Data.ToView() when writing the packet. This may require
copying when the packet is large, which puts the worse case in an even worse
situation.
This sent out in a separate preparation change as it requires syscall filter
changes. This change will be followed by the change for the adoption of the new
PacketHeader API.

gVisor incorrectly returns the wrong ARP type for SIOGIFHWADDR. This breaks
tcpdump as it tries to interpret the packets incorrectly.
Similarly, SIOCETHTOOL is used by tcpdump to query interface properties which
fails with an EINVAL since we don't implement it. For now change it to return
EOPNOTSUPP to indicate that we don't support the query rather than return
EINVAL.
NOTE: ARPHRD types for link endpoints are distinct from NIC capabilities
and NIC flags. In Linux all 3 exist eg. ARPHRD types are stored in dev->type
field while NIC capabilities are more like the device features which can be
queried using SIOCETHTOOL but not modified and NIC Flags are fields that can
be modified from user space. eg. NIC status (UP/DOWN/MULTICAST/BROADCAST) etc.

When we failed to create the new socket after adding the fd to
fdnotifier, we should remove the fd from fdnotifier, because we
are going to close the fd directly.
