d3ac9c1696 coils: ability to configure number of supported coils 
No change to current default behaviour of allocating 2000 coils.
However memory usage can be reduced by defining NMBS_MAX_COILS.

and Server roles. Also, add a little tests and example.

80fa8ef4ae Send platform argument to nmbs_callbacks 
This is useful for the same reasons as the arg is useful in the platform callbacks.

17aa0ca226 Support disabling individual server callbacks 
This helps reduce code size for systems that do not implement the full
set of function codes supported by the library.

f22b06082e Expose the function that calculates CRC 
Having access to this function is useful in a variety of cases:

- hand-crafting PDUs for unit tests
- implementing extensions of the protocol
- reusing the code for other purposes (e.g. firmware integrity check)

Update wording in comment for nmbs_client_create and nmbs_server_create 2022-06-24 19:06:37 +02:00

Document that the platform configuration and callbacks can be discarded after initialization 
`nmbs_client_create` accepts a `const nmbs_platform_conf* platform_conf` with configuration. Without reading the source code, it is not clear whether or not the object pointed to by `platform_conf` can be declared on the stack, or if it needs to be kept alive for the duration of the program (as would be the case if the implementation simply kept a pointer to the configuration instead of copying it by value). This PR adds an assurance that it is OK to discard the platform configuration after calling `nmbs_client_create`. Same idea for `nmbs_server_create`.

Support C++ 
Wrapping the header file in an `extern "C"` block prevents C++ compilers from mangling the function names.
