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.
Fixes: #384

It appears that when building tests, it would hardcode enabling building
of the c-ares static library. This was probably due to Windows limitations
in symbol visibility.
This change will use the static library if it exists for tests, always.
Otherwise, it will only forcibly enable static libraries for tests on
Windows.

The fuzz test files were not being distributed. This doesn't appear to be
a regression, it looks like they have never been distributed.

Issue #377 suggested that CMake builds for iOS with c-ares were broken. This PR adds an automatic Travis build for iOS CMake.

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.

EDNS retry should be based on FORMERR returned without an OPT RR record as per https://tools.ietf.org/html/rfc6891#section-7 rather than just treating any unexpected error condition as a reason to disable EDNS on the channel.

fake_hostent() was not supporting AF_UNSPEC, so when an ip address was specified when using AF_UNSPEC it would attempt to do a DNS lookup rather than returning a fake hostent using the ip address.

The c-ares test suite was hardcoded to use port 5300 (and possibly 5301, 5302) for the test suite. Especially in containers, there may be no guarantee these ports are available and cause tests to fail when they could otherwise succeed. Instead, request the system to assign a port to use dynamically. This is now the default. To override, the test suite still takes the "-p <port>" option as it always has and will honor that.

When generating the ares_sockaddr data by getaddrinfo() it was only filling
in certain members while leaving others uninitialized. This left garbage
data if a user tried to use the unset values. memset() the ares_sockaddr
to 0 prior to filling in the values to prevent this.

If a query is performed for dynamodb.us-east-1.amazonaws.com. with ndots=5, it was attempting to search the search domains rather than just attempting the FQDN that was passed it. This patch now at least attempts the FQDN first.
We may need to determine if we should abort any further searching, however as is probably intended.

A couple of for loops in Mac-specific code were using integer declarations
inside a for loop. Move the declaration to the top of the preceding
code block to retain c89 compliance.

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.
