A follow-up change will convert the networking code to use this standard
pipe implementation.

/dev/net/tun does not currently work with hostinet. This has caused some
program starts failing because it thinks the feature exists.

pipe and pipe2 aren't ported, pending a slight rework of pipe FDs for VFS2.
mount and umount2 aren't ported out of temporary laziness. access and faccessat
need additional FSImpl methods to implement properly, but are stubbed to
prevent googletest from CHECK-failing. Other syscalls require additional
plumbing.

TCP/IP will work with netstack networking. hostinet doesn't work, and sockets
will have the same behavior as it is now.
Before the userspace is able to create device, the default loopback device can
be used to test.
/proc/net and /sys/net will still be connected to the root network stack; this
is the same behavior now.

Users of the API only care about whether the copy in/out succeeds in
their entirety, which is already signalled by the returned error.

This is to fix a data race between sending an external signal to
a ThreadGroup and kernel saving state for S/R.

This saves one pointer dereference per VFS access.

- Added fsbridge package with interface that can be used to open
and read from VFS1 and VFS2 files.
- Converted ELF loader to use fsbridge
- Added VFS2 types to FSContext
- Added vfs.MountNamespace to ThreadGroup

These were out-of-band notes that can help provide additional context
and simplify automated imports.

FD table now holds both VFS1 and VFS2 types and uses the correct
one based on what's set.
Parts of this CL are just initial changes (e.g. sys_read.go,
runsc/main.go) to serve as a template for the remaining changes.

Because the abi will depend on the core types for marshalling (usermem,
context, safemem, safecopy), these need to be flattened from the sentry
directory. These packages contain no sentry-specific details.

Go 1.14+ sends SIGURG to Ms to attempt asynchronous preemption of a G. Since it
can't guarantee that a SIGURG is only related to preemption, it continues to
forward them to signal.Notify (see runtime.sighandler).
We should ignore these signals, as applications shouldn't receive them. Note
that this means that truly external SIGURG can no longer be sent to the
application (as with SIGCHLD).

This pattern (delete from map when dropping) is also used in epoll.RemoveEntry,
and seems like generally a good idea.

This patch holds taskset.mu when getting tty. If we don't
do this, it may cause a "unlock of unlocked mutex" problem,
since signalHandlers may be replaced by CopyForExec() in
runSyscallAfterExecStop after the signalHandlers.mu has
been holded in TTY().
The problem is easy to reproduce with keeping to do "runsc ps".
The crash log is :

* Rename syncutil to sync.
* Add aliases to sync types.
* Replace existing usage of standard library sync package.
This will make it easier to swap out synchronization primitives. For example,
this will allow us to use primitives from github.com/sasha-s/go-deadlock to
check for lock ordering violations.
