f3f01227e9 Fix some rare IOServiceGetMatchingServices failure on MacOSX 
We had reports of users always getting:

  IOServiceGetMatchingServices failed, data changed while iterating

The issue seems related to the function getMatchingServices that
returns an always-invalid iterator even if there are no actual services.

This is a workaround for this issue.

80a3721f8b darwin: use Go type wrappers to avoid declaring Go methods on C types. 
This is needed starting with Go 1.21 due to stricter enforcement of rules
about adding methods to existing types, now including C types.

See https://github.com/golang/go/issues/60725 for further details.

ff38fe2a78 add support for drain 
Tested on Mac OS, Linux and Windows with UART emulated on USB.

I wrote general BSD code, because it should work, but I am not able to test
it.

On Mac OS I am quite sure that drain behaves as expected because it fixed
an issue with buffer overflow (which OS does not report but fails).

For Windows it seems that drain is actually part of `Write`, because
`Write` was long and `Drain` was fast. But I have not found any mention in
Win32 docs about buffering and asynchronous write, so I put there flushing
code to be sure, and this code did not break anything.

For Linux `Drain` is also taking more time than writing so it looks working
too.

376ad6baaf Retry port enumeration 5 times before giving up (macosx) 
We observer errors getting the IOCalloutDevice string, this is a
tentative fix based on the hypotesis that the enumerator is
called too early during the USB enumeration phase.

1b32e59871 Remove unnecessary code, originally for checking disconnects 
The old code is no more needed when using overlapped I/O,
getOverlappedEvent() returns all required error codes.

Calling getCommState()/setCommState() every second in some
applications contributes to other downstream issues. For examples:

5e9cceab81 Fix potential small timeout bug on unix implementation 
A very small port.readTimeout may lead to a negative timeout if the
elapsed time between:

    deadline = time.Now().Add(port.readTimeout)

and

    timeout = time.Until(deadline)

is longer than port.readTimeout.

40f997f235 Fixed runtime build problem with darwin/amd64 
For some strange reason the interaction between the go-sqlite3 lib and
the go-serial produced a weird panic as described in:

https://github.com/bugst/go-serial/issues/115
https://github.com/bugst/go-serial/issues/116

The solution is to just upgrade the x/unix package to the latest
version available at the moment.
