We had several issues around the introducing of a verification callback. We reverted to use a `NATS_WITH_EXPERIMENTAL` build flag, but still, as part of the rewrite, there was something of the like: ``` SSL_verify_cb cb = _collectSSLErr; ``` Prior to 3.10, we would have called `SSL_set_verify(ssl, SSL_VERIFY_PEER, _collectSSLErr);` which was not causing an issue. The above would when building with OpenSSL prior to 1.1.1. So move the `cb` initialization as a `SSL_verify_cb` only when under the experimental flag, otherwise, invoke the same code we had prior to 3.10. Signed-off-by: Ivan Kozlovic <ivan@synadia.com>

Release notes will be: This release contains some breaking changes. See the "Changed" section below. * Build * Disable NATS Streaming by default by @mtmk in #770 * TLS * Require OpenSSL 1.1.1+ to compile. Removed the `NATS_BUILD_TLS_USE_OPENSSL_1_1_API` CMake variable by @kozlovic in #905 * The option `natsOptions_SetSSLVerificationCallback` signature was changed to replace the use of `SSL_verify_cb` (which required OpenSSL dependency in the `nats.h` file), to the new callback `natsSSLVerifyCb`. See documentation of `natsSSLVerifyCb` to see the cast needed to compile with this new header file by @kozlovic in #908 * Modification of a `natsOptions` object if it has TLS/SSL configuration and is actively used by connections will now return a `NATS_ILLEGAL_STATE` by @kozlovic in #912 * Options * Ability to load the trusted CA certificates from a directory using the new option `natsOptions_LoadCATrustedCertificatesPath` by @kerbert101 in #862 * Ability to connect via HTTP proxy for instance by adding a proxy connection handler using the new option `natsOptions_SetProxyConnHandler` by @wolfkor in #871 and @kozlovic in #897 * Ability to load the certificate chain and key from a file on every connection attempt using the new option `natsOptions_LoadCertificatesChainDynamic` by @Matus-p in #901 * Ability to perform concurrent TLS handshakes that may improve time it takes for concurrent connections to be established using the new option `natsOptions_AllowConcurrentTLSHandshakes ` by @kozlovic in #914. Issue was reported by @yanyongcheng in #899 * JetStream * Per-message TTL support (a NATS Server v2.11 feature) by @levb in #863 * Pull consumer priority groups (a NATS Server v2.11 feature) by @levb in #869 * ObjectStore support by @kozlovic in #902. Thanks to @jfflynn41 and @alex1891 for the feedback in #876 * JetStream * Handling of publish asynchronous timeouts by @kozlovic in #886. Issue reported by @yanyongcheng in #880 * Timer insertion by @kozlovic in #883. Issue reported by @yanyongcheng in #881 * EventLoop: * Handling of possible failure on initial attach by @kozlovic in #918 * LibEvent: `natsConnection_Close()` not closing the TCP connection by @kozlovic in #882. Issue was reported by @yanyongcheng in #879 * Libuv: Possible crash if connection is destroyed while receiving data by @kozlovic in #889. Issue was reported by @yanyongcheng in #888 * KeyValue * Keys, History or watcher's next may incorrectly return `NATS_TIMEOUT` by @kozlovic in #917/ Issue was reported by @ArashPartow in #916 * MicroServices: * Wrong marshaling of `average_processing_time` by @kozlovic in #892. Issue was reported by @Archie3d in #890 * Statistics error was always incremented by @kozlovic in #894. Issue was reported by @Archie3d in #893 * TLS * Unknown type name `SSL_verify_cb` by @kozlovic in #878. Issue was reported by @philipfoulkes in #877 * Initialization and cleanup code related to OpenSSL was removed since it was deprecated for versions post OpenSSL 1.1. A cleanup function pertinent to 1.1+ code was possibly causing a problem. By @kozlovic in #905. Issue was reported by @vdeters in #904 * Possible hang during handshake by @kozlovic in #907. Issue was reported by @etrochim in #906 * Protect calls to `SSL_read` and `SSL_write` with a mutex. Since the same `SSL` object is shared between different threads, the OpenSSL library requires a mutex to be used by @kozlovic in #913 * Memory allocation check by @wooffie in #868 * Add missing status text string by @oldnick85 in #872 and @kozlovic in #874 (the issue was not present in any published release and was introduced in #869) * Parsing of message headers with `NULL` or all-whitespace values by @habbbe in #873 * Removed some unused code related to handling of responses and added custom inbox with very long prefix test by @kozlovic in #885. Issue was reported by @yanyongcheng in #884 * Connection drain could cause missed reply and/or a 100ms delay by @kozlovic in #915. Issue was reported by @T-Maxxx in #911 * Build * Deprecated Ubuntu 20.04 in GitHub actions by @levb in #864 * Removed the older compiler jobs by @levb in #865 * Fixed Windows build to use the NATS Server main branch by @levb in #866 * @kerbert101 made their first contribution in #862 * @habbbe made their first contribution in #873 * @wolfkor made their first contribution in #871 * @Matus-p made their first contribution in #901 Signed-off-by: Ivan Kozlovic <ivan@synadia.com>
