Update from 1989 MIT license text to modern MIT license text (#556) ares (and thus c-ares) was originally licensed under the 1989 MIT license text: https://fedoraproject.org/wiki/Licensing:MIT#Old_Style_(no_advertising_without_permission) This change updates the license to the modern MIT license as recognized here: https://opensource.org/license/mit/ care has been taken to ensure correct attributions remain for the authors contained within the copyright headers, and all authors with attributions in the headers have been contacted for approval regarding the change. Any authors which were not able to be contacted, the original copyright maintains, luckily that exists in only a single file `ares_parse_caa_reply.c` at this time. Please see PR #556 for the documented approvals by each contributor. Fix By: Brad House (@bradh352)

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)

* Try to keep one section per platform, compiler and architecture,
* otherwise, if an existing section is reused for a different one and
* later on the original is adjusted, probably the piggybacking one can
* be adversely changed.
*
* In order to differentiate between platforms/compilers/architectures
* use only compiler built in predefined preprocessor symbols.
*
* 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.dist or ares_build.h,
* this is due to the following reason: file ares_build.h.dist is renamed
* to ares_build.h when the c-ares source code distribution archive file is
* created.
*
* File ares_build.h.dist is not included in the distribution archive.
* File ares_build.h is not present in the git tree.
*
* The distributed ares_build.h file is only intended to be used on systems
* which can not run the also distributed configure script.
*
* 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.
*
* If you check out from git on a non-configure platform, you must run the
* appropriate buildconf* script to set up ares_build.h and other local files.
