cmake: mark all the subprojects as explicitly C We don't need a C++ compiler but if we don't spell it out, cmake assumes it C + C++ compiler needed.

cmakelist: Augean Stables refactor Establish a new distributed CMake architecture with CMake code related to a source directory moving to be in the subdir in its own CMakeLists.txt. In particular, there's now one in ./lib which calls through to ones further down the directory tree like ./lib/plat/xxx, ./lib/roles/xxx etc. This cuts the main CMakelists.txt from 98KB -> 33KB, about a 66% reduction, and it's much easier to maintain sub-CMakeLists.txt that are in the same directory as the sources they manage, and conceal all the details that that level. Child CMakelists.txt become responsible for: - include_directories() definition (this is not supported by CMake directly, it passes it back up via PARENT_SCOPE vars in helper macros) - Addition child CMakeLists.txt inclusion, for example toplevel -> role -> role subdir - Source file addition to the build - Dependent library path resolution... this is now a private thing in the child CMakeLists.txt, it just passes back any adaptations to include_directories() and the LIB_LIST without filling the parent namespace with the details

asynchronous dns for ipv4 and ipv6 This adds the option to have lws do its own dns resolution on the event loop, without blocking. Existing implementations get the name resolution done by the libc, which is blocking. In the case you are opening client connections but need to carefully manage latency, another connection opening and doing the name resolution becomes a big problem. Currently it supports - ipv4 / A records - ipv6 / AAAA records - ipv4-over-ipv6 ::ffff:1.2.3.4 A record promotion for ipv6 - only one server supported over UDP :53 - nameserver discovery on linux, windows, freertos It also has some nice advantages - lws-style paranoid response parsing - random unique tid generation to increase difficulty of poisoning - it's really integrated with the lws event loop, it does not spawn threads or use the libc resolver, and of course no blocking at all - platform-specific server address capturing (from /etc/resolv.conf on linux, windows apis on windows) - it has LRU caching - piggybacking (multiple requests before the first completes go on a list on the first request, not spawn multiple requests) - observes TTL in cache - TTL and timeout use lws_sul timers on the event loop - ipv6 pieces only built if cmake LWS_IPV6 enabled

CTest: migrate and deprecate existing selftest scripts Replace the bash selftest plumbing with CTest. To use the selftests, build with -DLWS_WITH_MINIMAL_EXAMPLES=1 and `CTEST_OUTPUT_ON_FAILURE=1 make test` or just `make test`. To disable tests that require internet access, also give -DLWS_CTEST_INTERNET_AVAILABLE=0 Remove travis and appveyor scripts on master. Remove travis and appveyor decals on README.md.
