Switches the client/server direction of the shim-log pipe on Windows so
that the shim is the listener. This allows the containerd client to
reconnect as needed to the log streams.

A fifo on unix or named pipe on Windows will be provided to the shim.
It can be located inside the `cwd` of the shim named "log".
The shims can use the existing `github.com/containerd/containerd/log` package to log debug messages.
Messages will automatically be output in the containerd's daemon logs with the correct fiels and runtime set.

Adds retry support to AnonDialer if the pipe does not exist. This will
retry up to the timeout for the pipe to exist and connect. This solves
the race between the containerd-shim-* start command and the
reinvocation.

Fixes an issue where the runtime v2 was not using an absolute path to
the executable but setting the .Dir field on the exec.Cmd. This causes
the executable to need to be relative to .Dir but no shim is actually
copied to the bundle directory that its work dir is set to.

1. Moves the log message for each socket to the appropriate _unix and
_windows.go
2. Replaces all reference to Abstract Socket for Windows.
3. Adds support for ctrl+c on Windows to exit a shim.

Since windows does not require a signal handler, we just block on the
channel forever so that it does not exit.

Implements the various requirements for the runtime v2 code to abstract
away the unix/linux code into the appropriate platform level
abstractions to use the runtime v2 on Windows as well.
Adds support in the Makefile.windows to actually build the runtime v2
code for Windows by setting a shell environment BUILD_WINDOWS_V2=1
before calling make. (Note this disables the compilation of the Windows
runtime v1)
