This fixes the assertion failure reported here:
https://sourceware.org/pipermail/cygwin/2020-September/246160.html
with a simple test case here:
https://sourceware.org/pipermail/cygwin/2020-September/246188.html
That test case now fails as follows, as on Linux:
$ ./proc_bug.exe
open: Not a
The incoming path is allowed to have the form "$PID/fd/[0-9]*/.*"
provided the descriptor symlink points to a directory. Check that
this is indeed the case.

Yes, thanks for the suggestion. New patch(es) on the way. I called the header

This is necessary in order to be consistent with the following comment
in the definition of _Unwind_RaiseException() in the GCC source file
libgcc/unwind-seh.c:
The exception handler installed in crt0 will continue any GCC
exception that reaches there (and isn't marked non-continuable).
Define the pseudo keyword 'fallthrough' in woutsup.h to support this.

Don't try to read from fifo_client_handlers that are in the fc_closing
state. Experiments have shown that this always yields
STATUS_PIPE_BROKEN, so it just wastes a Windows system call.
Re-order the values in enum fifo_client_connect_state to reflect the
new status of fc_closing.

Rename the existing set_state() to query_and_set_state() to reflect
what it really does. (It queries the O/S for the pipe state.) Add a
new set_state() method, which is a standard setter, and a
corresponding getter get_state().
