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.

TestMultiContainerKillAll timed out under --race. Without logging,
we cannot tell if the process list is still increasing, but slowly,
or is stuck.

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.

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

- 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

Note that these are only implemented for tmpfs, and other impls will still
return EOPNOTSUPP.

Sometimes we get this error under TSAN:
"""
error getting process data from container: connecting to control server at PID
XXXX: connection refused
"""
The theory is that the top "sleep 20" was too short for TSAN, and the container
already exited, so we get connected refused. This commit changes the test to
let container signaling it's running by touching a file repeatedly forever
during the test.

The host /etc can contain config files which affect tests.
For example, bash reads /etc/passwd and if it is too big
a test can fail by timeout.

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

container_test was flaking because a small percentage of runs timed out. Tested
this fix with --runs_per_test=100.

Go 1.14 has a workaround for a Linux 5.2-5.4 bug which requires mlock'ing the g
stack to prevent register corruption. We need to allow this syscall until it is
removed from Go.

* Tests are picked for a shard differently. It now picks one test from each
block, instead of picking the whole block. This makes the same kind of tests
spreads across different shards.
* Reduce the number of connect() calls in TCPListenClose.

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.

In general, we've learned that logging must be avoided at all
costs in the hot path. It's unlikely that the optimizations
here were significant in any case, since buffer would certainly
escape.
This also adds a test to ensure that the caller identification
works as expected, and so that logging can be benchmarked.

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.

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.

* 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.
