Takashi Yano f7a77d0146 Cygwin: console: Fix conflict on shared names between sessions.
Previously, shared names in the console were created using get_minor().
However, get_minor() was not unique to the console across sessions.
This is because EnumWindows(), which is used to look for console windows,
cannot enumerate windows across sessions. This causes conflict on the
shared names between sessions (e.g. sessions of different users,
different services, a service and a user session, etc.).

With this patch, GetConsoleWindow() is used instead of get_minor().
GetConsoleWindow() has been used for the name of shared memory, which
should be unique to each console.
