b7debabd81 Wrap IoUring to ensure pending_ops is always correctly updated
Adds a struct WrappedIOUring which contains a IoUring and a pending_ops
field. Entry submission and popping from the queue is done through
functions operating on it, which also maintains pending_ops count

NOTE: This is a bit weird/hacky since in get_completion we create a
CompletionQueue and just call its next(). If it were a normal iterator
it would always return the same first item. However it is a queue posing
as an iterator which makes this work.

a7d735d368 Maintain pending io_uring ops count for early return on run_once
Add a `pending_ops` field to `InnerLinuxIO` struct which is incremented
for each operation submitted to the ring and decremented when they are
taken off the completion queue. With this, we can exit from run_once if
there are no pending operations. Otherwise, in that case, it would hang
indefinitely due to call of `ring.submit_and_wait(1)`

Switch anyhow to explicit `LimboError` type using thiserror crate, which
lets us make error handling more structured.

fd9af2739e wait for the read completion
The submit_and_wait command waits for `n` completion events.
We were providing an incorrect argument, which caused the issue.

The simulator does not do much, but does discover failures on Linux with
io_uring, though, so it's a start.

08b40f2af7 core/linux: Move I/O completion to io_uring
Move the Completion::complete() call to the io_uring machinery. We still
essentially do synchronous I/O because of the call to submit_and_wait()
in pread(), but let's take one step at a time...
