Such a stat accounts for all connections that are currently
established and not yet transitioned to close state.
Also fix bug in double increment of CurrentEstablished stat.

Some files were missing the last line break.

Note that these simply will use the same logic as getxattr and setxattr, which
is not yet implemented for most filesystems.

Java 11 parses /proc/self/mountinfo for cgroup information. Java 11.0.4 uses
the mount path to determine what cgroups existed, but Java 11.0.5 reads the
cgroup names from the superblock options.
This CL adds the cgroup name to the superblock options if the filesystem type
is "cgroup". Since gVisor doesn't actually support cgroups yet, we just infer
the cgroup name from the path.

CERT Advisory CA-96.21 III. Solution advises that devices drop packets which
could not have correctly arrived on the wire, such as receiving a packet where
the source IP address is owned by the device that sent it.

x86 and arm64 use a different stat struct in Linux
kernel, so the stat() syscall implementation has
to handle the file stat data separately.

There is a lot of code duplication for VFSv2 and this
serves as remind to keep the copies in sync.

This is similar to 'Truncate' in vfs1.

Files not implemented require VFSv2 plumbing into the kernel.
Also, cgroup is not implemented yet.

There was a very bare get/setxattr in the InodeOperations interface. Add
context.Context to both, size to getxattr, and flags to setxattr.
Note that extended attributes are passed around as strings in this
implementation, so size is automatically encoded into the value. Size is
added in getxattr so that implementations can return ERANGE if a value is larger
than can fit in the user-allocated buffer. This prevents us from unnecessarily
passing around an arbitrarily large xattr when the user buffer is actually too
small.
Don't use the existing xattrwalk and xattrcreate messages and define our
own, mainly for the sake of simplicity.
Extended attributes will be implemented in future commits.

Except for one under /proc/sys/net/ipv4/tcp_sack.
/proc/pid/* is still incomplete.

sys_clone has many flavors in Linux, and amd64 chose
a different one from x86(different arguments order).
Ref kernel/fork.c for more info.
