Ken Brown 1c0cf5f4f9 Cygwin: FIFO: reduce I/O interleaving
Add a bool member 'last_read' to the fifo_client_handler structure,
which is set to true on a successful read.  This is used by raw_read
as follows.

When raw_read is called, it first locates the writer (if any) for
which last_read is true.  raw_read tries to read from that writer and
returns if there is input available.  Otherwise, it proceeds to poll
all the writers, as before.

The effect of this is that if a writer writes some data that is only
partially read, the next attempt to read will continue to read from
the same writer.  This should reduce the interleaving of output from
different writers.
