For any API that takes a buffer and size pointer, check both pointers
and the pointed-to size and return UV_EINVAL in case of error.
Example:
```
int uv_foo(char* buffer, size_t* size) {
if (buffer == NULL || size == NULL || *size == 0)
return UV_EINVAL;
...
}
```
In order to "peek" the necessary size for dynamic allocation, the
following pattern can be used:
```
char *buf;
char scratch[1];
size_t len = sizeof(scratch);
int r;
r = uv_foo(scratch, &len);
assert(r == UV_ENOBUFS);
buf = malloc(len);
r = uv_foo(buf, &len);
...
```
Delete the fs_event_error_reporting test. It fails in different ways,
most frequently on the TSan sanitizer buildbot, due to running out of
file descriptors when that is not expected, or vice versa, *not*
running out of file descriptors when that *is* expected.
The test creates a large number of event loops and expects to,
eventually, hit EMFILE but it sometimes hits it too early, and
sometimes not at all.
I don't think TSan is really responsible here, it just makes the
invalid assumption in the test itself more visible.

Pass the loop to MAKE_VALGRIND_HAPPY() so it's explicit on which loop
needs to be cleaned up. Since it asserts on uv_loop_close(), need to
remove a couple of those that were being done before the call.
Cleanup where loop was assigned, so the entire test either uses loop or
uv_default_loop(). Not both.
Also take care of any reqs that may have been left uncleaned.
Increase the timer interval. That hopefully ameliorates the problem of
FSEvents.framework missing events on the macOS CI buildbot.
Not really a fix, more a mitigation.

On illumos and Solaris, fs events are implemented with
PORT_SOURCE_FILE type event ports. These are one-shot so
need re-arming each time they fire. Once they are armed
and an event occurs, the kernel removes them from the current
cache list and puts them on an event queue to be read by
the application.
There's a window in closing one of these ports when it could
have triggered and be pending delivery. In that case, the
attempt to disarm (dissociate) the event will fail with ENOENT
but libuv still goes ahead and closes down the handle. In
particular, the close callback (uv_close() argument) will be
called but then the event will subsequently be delivered if
the loop is still active; this should not happen.
Previously they were just being run incorrectly, but nothing wrong with
the test itself. We were also interpreting an ASAN failure as TEST_SKIP,
so test failures would not actually be reported as CI failures.
Fix a logic error where calling uv_fs_event_stop() from the event
callback tripped on a `handle->dir_handle != INVALID_HANDLE_VALUE`
assert in uv_fs_event_queue_readdirchanges().

This test sometimes times out on `macos` because not all the expected events are
received: the create and delete events may coalesce. To avoid it, make sure
not to start deleting the files until all the create events are received.
Also, take into account in the test that a create event of the `subdir`
directory can be detected even though we start watching for the events after its
creation.

This commit uses the Register File Interest feature on z/OS
to enable users to monitor file system events.
The poll call is used to check for file descriptors as well
as a message queue that z/OS will report file system events
on. The last item on the list used by poll will contain the
message queue id instead of a file descriptor.
Limitation:
Writes to a directory (that is, file creation and deletion)
do not generate a change message for a registered directory.

This change refactors the `fs_event_close_in_callback` test so that:
1. It creates directory entries instead of modifying them. This allows
the test to work on operating systems that use event ports to handle fs
events (e.g SmartOS and Solaris). When using event ports, watching
only a directory does not allow to receive events for files modified
within that directory, but events will be received for files _created_
within that directory.
2. it generates fs events _after_ the process entered the libuv event
loop. This is also needed to make the test work on operating systems
that use event ports to handle fs events (e.g SmartOS and Solaris),
because events are polled as part of running the event loop. That also
makes the test work on systems based on Kqueue and on AIX.

Previous behavior on Windows was to set the path to NULL for removed
and renamed fs events. This was because the path provided by
ReadDirectoryChangesW might (in rare cases) be an 8.3 short name which
could then no longer be converted to a long name after the path had
been removed or renamed. This meant that the user had to detect which
path was actually deleted or renamed and required the user to rescan
the entire watched subtree, taking several seconds or more for large
subtrees.
However, ReadDirectoryChangesW is publicly documented to emit 8.3
short names if the original handle for the changed path was opened
using an 8.3 short name, and libuv may already emit 8.3 short names for
other events if the path cannot be explicitly resolved to a long name.
This commit fixes the path for removed and renamed fs events, and does
not set the path to NULL, even if the path might be an 8.3 short name.
This makes it possible for the user to do a partial scan of the
subtree, restricting the scan to paths which match the long form or 8.3
short name (even if some of these are false positive matches). This
means that deletes and renames can now be detected accurately on
Windows within a few milliseconds.

fs_event_watch_dir and fs_event_watch_dir_recursive could fail randomly
due to the way in which the tests were written. Originally timers were
used to create, remove and recreate the test files but this could lead
to a race condition if the timeout used to delete the test files ran
before all file creation fs events were handled. On top of that, the
file removal timer scheduled another timer to recreate the test files
and that timer's timeout could also lead to the same condition.
The refactoring removed timers for the removal/recreation of the test
files and instead the fs event callback was updated to have the
necessary logic to drive the test file removal. We no longer recreate
the test files since it appears to be unnecessary.
