Brad House	b19c186ce7	Rework WinAFD event code (#811 ) We've had reports of user-after-free type crashes in Windows cleanup code for the Event Thread. In evaluating the code, it appeared there were some memory leaks on per-connection handles that may have remained open during shutdown, while trying to resolve that it became apparent the methodology chosen may not have been the right one for interfacing with the Windows AFD system as stability issues were seen during this debugging process. Since this system is completely undocumented, there was no clear resolution path other than to switch to the other methodology which involves directly opening `\Device\Afd`, rather than spawning a "peer socket" to use to queue AFD operations. The original methodology chosen more closely resembled what is employed by [libuv](https://github.com/libuv/libuv) and given its widespread use was the reason it was used. The new methodology more closely resembles [wepoll](https://github.com/piscisaureus/wepoll). Its not clear if there are any scalability or performance advantages or disadvantages for either method. They both seem like different ways to do the same thing, but this current way does seem more stable. Fixes #798 Fix By: Brad House (@bradh352)	5 months ago

Brad House	614bdd88b9	Tests: fix test cleanup race condition (#803 ) There was a thread passed data for processing that was cleaned up before thread exit, and it could cause a use-after-free in the test suite. This doesn't affect c-ares. This was found during trying to reproduce #798, but appears unrelated, don't use a helper thread as it isn't necessary. Fix By: Brad House (@bradh352)	5 months ago
Brad House	378d26144d	DNS RR TXT strings should not be automatically concatenated (#801 ) As per #738, there are usecases where the DNS TXT record strings should not be concatenated like RFC 7208 indicates. We cannot break ABI with those using the new API, so we need to support retrieving the concatenated version as well as a new API to retrieve the individual strings which will be used by `ares_parse_text_reply_ext()` to restore the old behavior prior to c-ares 1.20.

Brad House	70f10a85f3	DNS 0x20 implementation (#800 ) This PR enables DNS 0x20 as per https://datatracker.ietf.org/doc/html/draft-vixie-dnsext-dns0x20-00 . DNS 0x20 adds additional entropy to the request by randomly altering the case of the DNS question to help prevent cache poisoning attacks. Google DNS has implemented this support as of 2023, even though this is a proposed and expired standard from 2008: https://groups.google.com/g/public-dns-discuss/c/KxIDPOydA5M There have been documented cases of name server and caching server non-conformance, though it is expected to become more rare, especially since Google has started using this. This can be enabled via the `ARES_FLAG_DNS0x20` flag, which is currently disabled by default. The test cases do however enable this flag to validate this feature. Implementors using this flag will notice that responses will retain the mixed case, but since DNS names are case-insensitive, any proper implementation should not be impacted. There is currently no fallback mechanism implemented as it isn't immediately clear how this may affect a stub resolver like c-ares where we aren't querying the authoritative name server, but instead an intermediate recursive resolver where some domains may return invalid results while others return valid results, all while querying the same nameserver. Likely using DNS cookies as suggested by #620 is a better mechanism to fight cache poisoning attacks for stub resolvers. TCP queries do not use this feature even if the `ARES_FLAG_DNS0x20` flag is specified since they are not subject to cache poisoning attacks.

Brad House	51ca744459	Clean up header inclusion, simplification (#797 ) The header inclusion logic in c-ares is hard to follow. Lets try to simplify the way it works to make it easier to understand and less likely to break on new code changes. There's still more work to be done, but this is a good start at simplifying things.
