32-bit Windows (fix 252: demote on take)

Win.3.09-32

fix #252: demote on take

64-bit Windows (multiple client k-sessions)

This is a 64-bit native Windows binary that supports multiple client k-sessions (up to 10).

64-bit native Windows (with mutex)

This is a 64-bit binary version of Release "Win 3.06"
It adds a mutex to prevent the main thread and the socket thread from colliding.
All 860 regression tests pass.

See release "Win 3.05" for details on how to test the multiplexing.

32-bit native Windows (with mutex)

This is a 32-bit binary version of Release "Win 3.06".
It was compiled using a 32-bit version of Windows Vista.
As a test, the binary was run on a 64-bit version of Windows 8.1, and works there also.

The multiplexing of STDIN and a single client k-session seems to work fine.
This version includes the mutex code to insure the 2 threads do not collide.

However, of the 860 regression tests (that should pass) there are 3 that fail.
They are:
TC((1;"wsfull"),@[.:;"0I#0";:])
TC((1;"wsfull"),@[.:;"&0I";:])
TC((1;"wsfull"),@[.:;"!0I";:])
This 32-bit binary for Windows does not handle "wsfull" gracefully,
It stops working with a message from Windows stating that k.exe has stopped working
and that Windows will close the program.

See release "Win 3.05" for details on how to test the multiplexing.
