Avoid aborts when a thread signals an error

* src/thread.h (struct thread_state): Add members
m_waiting_for_input and m_input_available_clear_time.
(waiting_for_input, input_available_clear_time): New macros.
* src/keyboard.c (waiting_for_input, input_available_clear_time):
Remove; they are now macros that reference the current thread.
(Bug#25171)
* src/w32select.c: Don't include keyboard.h.

* test/src/thread-tests.el (thread-errors): New test.
