test: fix test-ipc tests

A couple of ipc tests failures where undercover by the previous commit.

- In `ipc-heavy-traffic-deadlock-bug`, `uv_shutdown` can fail with
`UV_ENOTCONN`. Allow it.
- `ipc_closed_handle` was failing consistently on `Centos6` because the
first large write was completed in just one syscall. Also, there were
issues with the lifetime of the `uv_write_t` requests. Refactor the
test so it passes consistently on `Centos6` while fixing the
`uv_write_t` issues.

When releasing key with Alt pressed, the reported event has

that Alt+numpad combination is used. This fixes this issue by removing

is enough to detect the Alt+numpad case.

unix: don't send handle twice on partial write

Guard against sending the handle over the UNIX domain socket twice
when the first sendmsg() didn't write all bytes.

The changes to src/win partially undo changes made earlier this year,
see the referenced pull request for details.

Libuv never made promises about the value of `req->send_handle` at
different points in time so this should be a safe, non-breaking change.

No tests because this particular condition is hard to hit reliably
across platforms. I spent a lot of time trying to write one but it
turned out hideously complex, and worse, flaky.

aix: manually trigger fs event monitoring

In AIX, fs watch feature leverages AHAFS function.
According to AHAFS, monitoring of events does not
begin until the monitoring application issues a select()
or a blocking read() call. In edge cases where the watch
request as well as fs event both occurs in single event
loop cycle, we miss the event, as the event monitors are
created but not yet registered in the current cycle,
instead only enqueued into the poll structure, that will
be taken up with the OS on the loop edge only.

Trigger a select call in-line on the monitoring fd, that
tells AHAFS to kick-start the moitoring.

win: fs: fix `FILE_FLAG_NO_BUFFERING` for writes

On Windows, `fs__open()` maps `UV_FS_O_DIRECT` to
`FILE_FLAG_NO_BUFFERING`.

When `access` is only `FILE_GENERIC_READ` this succeeds, but when
`access` is `FILE_GENERIC_WRITE` this returns an error:

```
0x00000057, ERROR_INVALID_PARAMETER, The parameter is incorrect.
```

The reason is that `FILE_GENERIC_WRITE` includes `FILE_APPEND_DATA`,
but `FILE_APPEND_DATA` and `FILE_FLAG_NO_BUFFERING` are mutually
exclusive:

```
FILE_GENERIC_WRITE = STANDARD_RIGHTS_WRITE |
FILE_WRITE_DATA |
FILE_WRITE_ATTRIBUTES |
FILE_WRITE_EA |
FILE_APPEND_DATA |
SYNCHRONIZE
```

This incompatibility between access and attribute flags does not appear
to be documented by Microsoft for `FILE_FLAG_NO_BUFFERING` but it is
indirectly documented under [NtCreateFile](https://bit.ly/2rm5wRT):

```
FILE_NO_INTERMEDIATE_BUFFERING
The file cannot be cached or buffered in a driver's internal buffers.
This flag is incompatible with the DesiredAccess FILE_APPEND_DATA flag.
```

The solution is to remove `FILE_APPEND_DATA` from the access flags when
`FILE_FLAG_NO_BUFFERING` is set. Note that this does not prevent
appends, since `FILE_GENERIC_WRITE` also includes `FILE_WRITE_DATA`,
which in turn allows appends.
