It concerns only the files in 'tests' directory.

Protects against crafted write requests with a large quantity but a small
byte count. If address + quantity was in the mapping space of the server
and quantity greater than the response size, it was possible to crash
the server.

The sleep/flush sequence improves the handling of following requests.

Thank you MarjanTomas and SwissKnife.

Thank you Petr Gladkiy and MarjanTomas.
Sorry for the delay...

From Michael Heimpold:
Just a nitpick: the INADDR_* macros are defined in host byte order,
compare INADDR_LOOPBACK. So it would be reasonable to wrap this with
htonl(INADDR_ANY). However, every experienced socket programmer should
know that INADDR_ANY equals 0.0.0.0, passing it through htonl does not
have any effect.

- protect against NULL IP address BTW
- update documentation

- allow an empty string or NULL for node argument
- protect against NULL in service argument
- new test for NULL service
- update documentation

Thanks to vgrin for the report

It's never too late to remove 261 lines of code ;)

Thanks to Marjan Tomas

Change API of function for libmodbus v3.2.0

Thanks to Perry Kundert for bug report and initial patches.

The report slave id function returns the number of bytes as the _return_
value, and does not include it as the first byte in the dest buffer.

Update documentation to reflect reality.  There's no missing
functionality, just slightly confusing documentation.

- add byte timeout tests (TCP backend only)
- update and improve documentation
- long timeout values are now uint32_t so it changes the API
  to disable byte timeout

Thank you AlexMaz.

Not applied to libmodbus constants for now...

POSIX-1.2001 for fd_set. Thanks to spider391Tang.

- update documentation
- 5 new tests
- updated NEWS file
- avoid include of time.h
