It gets rid of holding state of the io.Reader offset (which is anyways held by
the vfs.FileDescriptor struct. It is also odd using a io.Reader becuase we
using io.ReaderAt to interact with the device. So making a io.ReaderAt wrapper
makes more sense.
Most importantly, it gets rid of the complexity of extracting the file reader
from a regular file implementation and then using it. Now we can just use the
regular file implementation as a reader which is more intuitive.

Also adds stress tests for block map reader and intensifies extent reader tests.

Adds feature to launch from an open host FD instead of a binary_path.
The FD should point to a valid executable and most likely be statically
compiled. If the executable is not statically compiled, the loader will
search along the interpreter paths, which must be able to be resolved in
the Sandbox's file system or start will fail.

syscall.POLL is not supported on arm64, using syscall.PPOLL
to support both the x86 and arm64. refs #63

This provides the following benefits:
- We can now use pkg/fd package which does not take ownership
of the file descriptor. So it does not close the fd when garbage collected.
This reduces scope of errors from unexpected garbage collection of io.File.
- It enforces the offset parameter in every read call.
It does not affect the fd offset nor is it affected by it. Hence reducing
scope of error of using stale offsets when reading.
- We do not need to serialize the usage of any global file descriptor anymore.
So this drops the mutual exclusion req hence reducing complexity and
congestion.

Allocate a larger memory buffer and combine multiple copies into one copy,
to reduce the number of copies from kernel memory to user memory.

This introduces two new types of Emitters:
1. MultiEmitter, which will forward events to other registered Emitters, and
2. RateLimitedEmitter, which will forward events to a wrapped Emitter, subject
to given rate limits.
The methods in the eventchannel package itself act like a multiEmitter, but is
not actually an Emitter. Now we have a DefaultEmitter, and the methods in
eventchannel simply forward calls to the DefaultEmitter.
The unimplemented syscall handler now uses a RateLimetedEmitter that wraps the
DefaultEmitter.

This test flaked on my current CL. Linux makes no guarantee
that two inodes will consecutive (overflows happen).

Unfortunately, Linux's ip_tables.h header doesn't compile in C++ because it
implicitly converts from void* to struct xt_entry_target*. C allows this, but
C++ does not. So we have to re-implement many types ourselves.
Relevant code here:

By following the directions in the README file, these Dockerfiles can be
built and used to run native language tests for their respective runtimes.

This allows the user code to add a network address with a subnet prefix length.
The prefix length value is stored in the network endpoint and provided back to
the user in the ProtocolAddress type.

The different containers in a sandbox used only one pid
namespace before. This results in that a container can see
the processes in another container in the same sandbox.
This patch use different pid namespace for different containers.
