[CStringSyntaxChecker] Check strlcpy sizeof syntax
The last argument is expected to be the destination buffer size (or less).
Detects if it points to destination buffer size directly or via a variable.
Detects if it is an integral, try to detect if the destination buffer can receive the source length.
Updating bsd-string.c unit tests as it make it fails now.
