rtapi_strlcpy - RTAPI string manipulation functions

       rtapi_strlcpy will copy at most 'sz' chars from 'src'  to  'dst'.   Always  leaves  'dst'  NUL-terminated
       except if sz is 0.

       rtapi_strxcpy(dst,  src)  checks  that dst is an array with known size, and calls rtapi_strlcpy(dst, src,
       sizeof(dst)).  If it is not an array with a known size, it is a (possibly cryptic!) syntax error.

       rtapi_strlcat will append characters from 'src' to 'dst', stopping when the end of 'src' is  reached,  or
       'dst' uses 'sz' bytes of storage including the trialing nul.

       rtapi_strxcat(dst,  src)  checks  that dst is an array with known size, and calls rtapi_strlcat(dst, src,
       sizeof(dst)).  If it is not an array with a known size, it is a (possibly cryptic!) syntax error.

       rtapi_strlcpy - RTAPI string manipulation functions

       The total length of the string strlcpy or strlcat tried to create.  For strlcpy() that means  the  length
       of src.  If the return value is greater than or equal to sz, the result was truncated.
