2f0c789ea1 More work to address #1391 
Properly set read_fiber and write_fiber to NULL when unused.
This was causing extra listening in the poll implemenation leading to
busy loops where a read was accidentally listening for POLLOUT.

a9b8f8e8a9 Address #1391 - set fd to negative value if not used. 
See https://groups.google.com/g/comp.unix.programmer/c/bNNadBIEpTo/m/G5gs1mqNhbIJ?pli=1 for a conversation and workaround.

c9897f99c3 Address #1405 - don't try and resume fibers that can't be resumed. 
FOr fibers that _can_ be resumed and then get cancelled, the sched_id
will be incremented later prevent the spurious wake ups.

a10b4f61d8 Address #1337 (leet!). 
Changes a few scheduling details and adds a 0 byte explicitly to
symbols created via gensym.

3b189eab64 Fix #1321, poll event loop CPU usage issue 
A stream may have a fiber attached for memory management purposes, but
not actually be waiting on anything. Be more seletive with poll, which
is not edge-triggered, to not poll for readiness on these streams.

Calvin Rose
7bfb17c209 Lots of work to make iocp work again. 
Big issue with IOCP vs. poll variants is that the overlapped
structures have a longer lifetime than intermediate state needed
for epoll. One cannot free overlapped structures after closing a
handle/socket, like one can do with any intermediate state when using
readiness-based IO.

5f2e287efd Make epoll event loop use EPOLLET and not reregister file descriptors. 
This results in fewer system calls and presumably more effcient code. It
also brings the epoll (and kqueue) code more in line with how the
windows IOCP code works, incidentally.

This commit was to address issues with a use after free error in the
windows event loop, but the erroneous code was later reworked.

81f35f5dd1 Redo state management for Janet listeners. 
Make more use of the built in GC code for abstracts to
be sure things are more correct. Issue before was streams could
be freed before IOCP events arrived.
