Fix rfc_{n,}casecmp functions (#2058)
rfc_casecmp was broken because reaching terminator for str1 was used as
a terminal condition and str2 may be shorter than str1, resulting in an
oob read condition for str2.

rfc_ncasecmp was broken because it checked if n characters were checked
or if BOTH pointers reached their terminator, however the strings may
be different lengths and also less than n characters in length, meaning
that they don't both reach their terminators at the same time,
resulting in an oob read condition.
