* modbus_reply: fix copy & paste error in sanity check (fixes stephane#614)
While handling MODBUS_FC_WRITE_AND_READ_REGISTERS, both address offsets
must be checked, i.e. the read and the write address must be within the
mapping range.
At the moment, only the read address was considered, it looks like a
simple copy and paste error, so let's fix it.

* Add contributors to .clabot
* VCLinkerTool version 1.0.0 to 1.0, NO link error
Even the newest visual studio use /VERSION:major[.minor] .
It means link.exe /VERSION:1.0 just need two version number .
If Version = 1.0.0 , when visual studio link the program , vs will produce link error:

* Do not change the behavior for non-windows OS.
* Reduce memory use of TCP PI backend (closes stephane#621)
- allocate exact memory required to store node and service strings
instead of around 1kb of static memory.
- accept NULL value of service to use default Modbus port number (502)
- unit test updated
The new documentation will be updated in another commit.

* Add 0x34d to .clabot
* Add jordanjohnson56 to CLA
* Have autogen.sh fail if autoreconf fails
If the autoreconf program does not succeed, autogen.sh
should not succeed either.
The definition of "succeed" being "exit with exit code 0".
* Have autoreconf fail if LT_INIT is not defined
If the LT_INIT macro is not available in a *.m4 file to be
found during the autoreconf run, it is impossible to build
a useful configure script.
Therefore, we blacklist the LT_INIT macro so when it appears
unexpanded in the configure script, autoreconf will report
the failure instead of silently creating a broken configure.
This is generally a good idea for any macro not shipped with
Automake or Autoconf.
* Fix doc links
* test the protocol id for 0
previous test would fail if one byte was non zero.
* Fix double negative in tests
* New quirks handler (closes stephane#38 stephane#533)
Useful functions when you are confronted with equipment which does
not respect the protocol, which behaves strangely or when you wish
to move away from the standard.
Thank you @mhei for the great initial version.

- check of req length before use in memcpy for mask write register
Related to df79a02
* Revert "Fix float endianness issue on big endian architecture." and fix test suite and setter functions.
This reverts commit 49af73d.
* Prepare NEWS file for next release
* Use port 502 instead of 1502 in documentation (closes stephane#771)
The default port number of Modbus is 502 but it requires privileges on
Linux.
* HAVE_NETINET_IN_H as guard around header (stephane#765)
Thank you @diplfranzhoepfinger
* RTU - Check CRC before filtering on slave ID
* Minor
* Bump version to 3.1.11
* modbus-tcp.c doesn't include config.h, possible workaround - defining HAVE_NETINET_IP_H directly in modbus-tcp.c for Linux builds to force including <netinet/ip.h> which provides IPTOS_LOWDELAY definition
