There is too much inconsistency between platforms for arpa/nameser.h and arpa/nameser_compat.h for the way the current files are structured. Still load the respective system files but make our private nameser.h more forgiving.

NodeJS passes NULL for addr and 0 for addrlen parameters to ares_parse_ptr_reply(). On systems where malloc(0) returned NULL, this would cause the function to return ARES_ENOMEM, but the cleanup wasn't handled properly and would crash.
This patche fixes that bug, and also hardens ares_free_hostent() to not leak memory during cleanup.

Some systems may return either NULL or a valid pointer on malloc(0). c-ares should never call malloc(0) so lets return NULL so we're more likely to find an issue if it were to occur.
Buffered fread() reads 4096 bytes which is completely unnecessary and potentially may cause problems.
I discovered this on private linux configuration where custom /dev/urandom implementation has poor performance.

When c-ares is being built as static on Win32, CARES_STATICLIB must
be defined, but it wasn't being pulled in for the tools.

It appears some outside projects were relying on macros in ares_dns.h, even though it doesn't appear that header was ever meant to be public. That said, we don't want to break external integrators so we should distribute this header again.

ai_socktype and ai_protocol were ignored from the hints input. They are now
duplicated into the output as expected. Currently no sanity checks on
proper values are taking place.

If there are more ttls returned than the maximum provided by the requestor, then
the *naddrttls response would be larger than the actual number of elements in
the addrttls array.
This bug could lead to invalid memory accesses in applications using c-ares.

If hquery->name is empty (=="\0"), &hquery->name[strlen(hquery->name)-1] would point to "random" place in memory. This is causing some of my address sanitizer tests to fail.

CAA (Certification Authority Authorization) was introduced in RFC 6844.
This has been obsoleted by RFC 8659. This commit added the possibility
to query CAA resource records with adig and adds a parser for CAA
records, that can be used in conjunction with ares_query(3).

No longer any relation to libcurl since '<libcurl-root>/packages/DOS/common.dj' is dropped.
This Makefile.dj has been tested on Win-10 only (using the Windows hosted djgpp cross compiler).

Originally started by Daniel Stenberg (@bagder) with #123, this patch reorganizes the c-ares source tree to have a more modern layout. It also fixes out of tree builds for autotools, and automatically builds the tests if tests are enabled. All tests are passing which tests each of the supported build systems (autotools, cmake, nmake, mingw gmake). There may be some edge cases that will have to be caught later on for things I'm not aware of.
