Cygwin: console: Set ENABLE_PROCESSED_INPUT when disable_master_thread
Currently, ENABLE_PROCESSED_INPUT is set in set_input_mode() if
master_thread_suspended is true. This enables Ctrl-C handling when
cons_master_thread is suspended, since Ctrl-C is normally handled
by cons_master_thread.
However, when disable_master_thread is true, ENABLE_PROCESSED_INPUT
is not set, even though this also disables Ctrl-C handling in
cons_master_thread. Due to this bug, the command
C:\cygwin64\bin\sleep 10 < NUL
in the Command Prompt cannot be terminated with Ctrl-C.
This patch addresses the issue by setting ENABLE_PROCESSED_INPUT
when either disable_master_thread or master_thread_suspended is true.
This bug also affects cases where non-Cygwin Git (Git for Windows)
launches Cygwin SSH. In such cases, SSH also cannot be terminated
with Ctrl-C.
