Avoid buffer overflow in RC4 loop comparison (#336) The rc4 function iterates over a buffer of size buffer_len who's maximum value is INT_MAX with a counter of type short that is not guaranteed to have maximum size INT_MAX. In circumstances where short is narrower than int and where buffer_len is larger than the maximum value of a short, it may be possible to loop infinitely as counter will overflow and never be greater than or equal to buffer_len. The solution is to make the comparison be between types of equal width. This commit defines counter as an int. Fix By: Fionn Fitzmaurice (@fionn)

* This header file shall only export symbols which are 'cares' or 'CARES'
* prefixed, otherwise public name space would be polluted.
*
* NOTE 2:
* -------
*
* Right now you might be staring at file ares_build.h.in or ares_build.h,
* this is due to the following reason:
*
* On systems capable of running the configure script, the configure process
* will overwrite the distributed ares_build.h file with one that is suitable
* and specific to the library being configured and built, which is generated
* from the ares_build.h.in template file.
