Today, the global uncaught exception handler is the only
place where asyncId 0 is not ignored and we still proceed
to call emitAfter. This would've already failed one of
our correctness tests in async_hooks if not for some other
code meant to handle a different edge case.

after writing the 5 bytes is reported. Updating the mtime of the file

This allows transitioning the entire following sync and async execution
sub-tree to the given async storage context. With this one can be sure
the context binding will remain for any following sync activity and all
descending async execution whereas the `run*(...)` methods must wrap
everything that is intended to exist within the context. This is helpful
for scenarios such as prepending a `'connection'` event to an http
server which binds everything that occurs within each request to
the given context. This is helpful for APMs to minimize the need
for patching and especially adding closures.

This commit introduces store as the first argument in
AsyncLocalStorage's run methods. The change is motivated by the
following expectation: most users are going to use a custom object
as the store and an extra Map created by the previous implementation
is an overhead for their use case.
Important note. This is a backwards incompatible change.
It was discussed and agreed an incompatible change is ok
since the API is still experimental and the modified
methods were only added within the last week so usage
will be minimal to none.

This completely refactors the `expectsError` behavior: so far it's
almost identical to `assert.throws(fn, object)` in case it was used
with a function as first argument. It had a magical property check
that allowed to verify a functions `type` in case `type` was passed
used in the validation object. This pattern is now completely removed
and `assert.throws()` should be used instead.
The main intent for `common.expectsError()` is to verify error cases
for callback based APIs. This is now more flexible by accepting all
validation possibilites that `assert.throws()` accepts as well. No
magical properties exist anymore. This reduces surprising behavior
for developers who are not used to the Node.js core code base.
This has the side effect that `common` is used significantly less
frequent.

Under high load 2 types of issues arise with this test.
* filesystem calls gets queued even when the 'sync' is used which leads
to async_hooks being called with the events of tmpdir clean or
initial file write after clean.
This is solved by counting all 'change' calls while making sure there
is no dependency of StatWatcher's on one another and the expected
changes are waited for.
* some events are getting lost with the current
clean->write->write_and_watch strategy. Specifically I observed the
file size going from 0 to 5 entirely skipping 3 even though the write
call was there (this happened reliably on -j128).
So I've changed the strategy to avoid additional write considering
this still tests the hooks correctly.
This may indicate some sort of bug in async_hooks though I'm not sure.

This improves dgram performance by avoiding unnecessary async
operations.
One issue with this commit is that it seems hard to actually create
conditions under which the fallback path to the async case is
actually taken, for all supported OS, so an internal CLI option
is used for testing that path.
Another caveat is that the lack of an async operation means
that there are slight timing differences (essentially `nextTick()`
rather than `setImmediate()` for the send callback).

On systems where core dumps are enabled, that actually generates an
unnecessary core dump. Set `ulimit -c 0` before spawning the subprocess.
