16 range_bufinbuf checks that the buffer buf2[0..len2-1] lies entirely in
17 buf1[0..len1].
18
19 If the buffer is 0-terminated and you don't know the length beforehand,
20 use range_strinbuf, range_str2inbuf or range_str4inbuf instead.
21
23 If one of the buffers is implausible (buf is NULL or buf+len has an
24 integer overflow), return 0.
25
26 If the buf2[0..len2-1] lies before or after buf1[0..len1-1], return 0.
27
28 Otherwise, return 1.
