EventLoop: fix std.Io.Condition implementation
...
1. a fiber can't put itself on a queue that allows it to be rescheduled
2. allow the idle fiber to unlock a mutex held by another fiber by
ignoring reschedule requests originating from the idle fiber

EventLoop: fix futex usage
...
How silly of me to forget that the kernel doesn't implement its own API.
The scheduling is not great, but at least doesn't deadlock or hammer.

EventLoop: get file operations working

Something is horribly wrong with scheduling, as can be seen in the
debug output, but at least it somehow manages to exit cleanly...

EventLoop: move context after the async closure
...
This avoids needing to store more sizes and alignments. Only the result
alignment needs to be stored, because `Fiber` is at a fixed zero offset.

EventLoop: fix incorrect alignment panic
...
When the previous fiber did not request to be registered as an awaiter,
it may not have actually been a full blown `Fiber`, so only create the
`Fiber` pointer when needed.
