For socket types that take an address, it would be useful to return
that with 'filename'. If not, we can continue to return the
socket type.

Now a default constructor is created, as an alias for defaultconstrutor.
The constructor is passed the arguments to new and by default
this accepts a dictionary that is checked for valid instance variables and sets them.

However the constructor can be replaced by one that takes arbitrary arguments.
Thus we can how have:

  a new -optiona -optionb

And the constructor is invoked with arguments '-optiona -optionab'.

This makes object initialisation more flexible.

** Note: This is an incompatible change if you have classes with a constructor
and you create object instances with new <dict>.

When checking for "weak" references where the only reference is in the
command hash table, need to check the reference count of the key in the hash
table (this is the command name), not the reference count of the object
we are using to look up the command. Without this it is possible that a reference
(typically a lambda) will be collected even though there is still a reference to it.

In fact since open |... already provides a pipe on output
there is no need to create one manually, so the first test
can run under Tcl too.

On win32, a process is identified by a HANDLE, but for identifying
a running process we should use GetProcessId() to return a meaningful integer.

This means we need to be able to back and forth between a pid and a process handle
(phandle). We also need to be careful to get the pid before the process handle closes
since it isn't available afterwards.

Also call the handle to intptr_t for open_osfhandle() to avoid a compiler warning.
