016ed8966a poll now handles monotonic clocks, not system clocks 
I initially had it backwards. It is not sensible to poll on a system
clock timeout because the system clock is not necessarily monotonic!
only a monotonic clock makes sense for a timeout.

7f7a0be938 wasi-c2: implement a synchronous poll_oneoff in terms of yanix 
doesnt work on unix yet! also breaks all the rules about using the
cap-std family instead of rawfds! but this is cool and im happy with it

b84c4d7488 poll_oneoff test: if you subscribe to a badf, the whole call fails with badf 
rather than the results telling you an individual file was a badf.

why? i think the old behavior was too clever, and makes it harder to
write a scheduler.

* what should the call do when you pass it some badf and some not-badf?
i don't think anything besides exiting early is the correct answer.
* the results vector tells you something that the scheduler had to say
about the file, not about your inputs. the errno of the function
always says what the validity of the inputs was

9a1ce1a272 TEMPORARY: inherit stdio for the wasi ctx 
this is unfortunate but the poll_oneoff test insists on polling on stdio
handles. to undo this temporary fix later, lets rewrite the test to open
some regular files from the scratch directory and poll on them instead.

94467bcd9a wiggle: bugfix, generated code should use Names::runtime_mod not wiggle 
as the crate from which these deps come.

I worked around this in lucet, but I'll be able to revert that
workaround.

d56d2f0219 directory seek test: code does not agree with comment. Fix code. 
the directory was opened with the seek right, and this test says that it
was asserting that the seek right was present. However, the test was
actually asserting that the seek right was *not* present.

This fixes the code of the test, because I believe the comment is
correct.
