Concatenate two strings.

size_t strlcat_PF(
	char * dst,
	uint_farptr_t src,
	size_t siz)

The strlcat_PF() function is similar to strlcat(), except that the src string must be located in program space (flash) and is addressed using a far pointer

Appends src to string dst of size n (unlike strncat(), n is the full size of dst, not space left). At most n-1 characters will be copied. Always NULL terminates (unless n <= strlen(dst))
