Expose library/utility functions to tools (#860) The tools like `adig` and `ahost` can take advantage of some of the library functions within c-ares. We can't really split these library functions into a helper library without possibly breaking users. Technically if we could guarantee they rely on pkg-config or cmake helpers we could make it work ... we can revisit that in the future, maybe if we make a c-ares 2.0 where people might expect more breakage (but I still wouldn't want to break API/ABI). So what this does is it just exports some symbols in headers that aren't distributed so end users aren't meant to use the symbols, but any utilities or tests built by c-ares can. It does clutter up some of the namespace, but all these symbols are guaranteed to be prefixed with `ares_` so there shouldn't ever be symbol clashes due to this for end users and its not so many symbols that it should affect any load times. There will be **zero** API/ABI guarantees for these symbols. They can change from release to release, this is ok since they are not public. I'm not entirely thrilled with doing this solution, but I want to avoid thing like hand-written parsers, such as is used in #856. Authored-By: Brad House (@bradh352)

Autotools: rework to simplify and fix recent issues (#674) Completely rework the autotools build system, issues have cropped up due to the complexity and could cause issues on even semi-modern Linux systems (Ubuntu 20.04 for example). Changes include: Remove all curl/xc/cares m4 helper files, they go overboard on detections of functions and datatypes. Go back to more plain autoconf macros as they've come a long way over the years. Use known systems and heuristics to determine datatypes for functions like send() and recv(), rather than the error prone detection which required thousands of permutations and might still get it wrong. Remove unneeded configure arguments like --enable-debug or --enable-optimize, its more common for people to simply pass their own CFLAGS on the command line. Only require CARES_STATICLIB definition on Windows static builds, its not necessary ever for other systems, even when hiding non-public symbols. Remove some function and definition detections that were never used in c-ares The test framework is now embedded into the toplevel configure system, there was no need to chain build the test system as it is never built externally to c-ares. As a side-effect of the changes, a configure run completes in about 25% of the original time. This has been tested on various Linux distributions (of varying age), FreeBSD, MacOS, Windows (via MSYS2 with Mingw), and Solaris10/11 (by @dfandrich), AIX 7.3 (by @dfandrich). It is not unlikely that this may have broken more esoteric or legacy systems, and we'll likely need to be ready to accept bug reports and patches, but it has removed over 10k lines of build system code. It is very likely any issues that crop up will add far fewer lines of code to fix such systems. Fixes Bug: #670 Fix By: Brad House (@bradh352)

Use external GoogleTest instead of bundling it (#655) GoogleTest should be unbundled. Google changed their guidance a few years back and modern versions of google test cannot build the bundling code file. This PR also updates to use C++14 as is required by modern GoogleTest versions.

Apple: reimplement DNS configuration reading (#750) The DNS configuration for apple is stored in the system configuration database. Apple does provide an emulated `/etc/resolv.conf` on MacOS (but not iOS), it cannot, however, represent the entirety of the DNS configuration. Alternatively, libresolv could be used to also retrieve some system configuration, but it too is not capable of retrieving the entirety of the DNS configuration. Attempts to use the preferred public API of `SCDynamicStoreCreate()` and friends yielded incomplete DNS information. Instead, that leaves some apple "internal" symbols from `configd` that we need to access in order to get the entire configuration. We can see that we're not the only ones to do this as Google Chrome also does: https://chromium.googlesource.com/chromium/src/+/HEAD/net/dns/dns_config_watcher_mac.cc These internal functions are what what`libresolv` and `scutil` use to retrieve the dns configuration. Since these symbols are not publicly available, we will dynamically load the symbols from `libSystem` and import the `dnsinfo.h` private header extracted from: https://opensource.apple.com/source/configd/configd-1109.140.1/dnsinfo/dnsinfo.h Fix By: Brad House (@bradh352)
