Function and macro properties contained in ECLAIR/call_properties.ecl are of
general interest: this patch moves these annotations in a generaric JSON file
in docs. In this way, they can be exploited for other purposes (i.e. documentation,
other tools).
Add rst file containing explanation on how to update function_macro_properties.json.
Add script to convert the JSON file in ECL configurations.
Remove ECLAIR/call_properties.ecl: the file is now automatically generated from
the JSON file.

Change cast type from void* to uintptr_t.
void* type cast resulted in violation of the Rule, a cast to type uintptr_t
is more appropriate type-wise.

Function ERR_CAST contains a violation of MISRA C:2012 Rule 11.8,
whose headline states:
"A conversion shall not remove any const, volatile or _Atomic qualification
from the type pointed to by a pointer".
Since the function has no users, it is appropriate to remove it.

The macro 'container_of' violates the Rule because it casts away any
qualifier to do pointer arithmetic, but making the macro definition compliant
would add additional complexity, therefore a deviation is introduced.
