We use a linked list to hold timers. They are ordered by absolute time. Inserting a timer was always looking for the spot starting at the beginning. We now check first if it should be added directly at the end of the list, which in most cases - say creating new connections that creates a timer for sending PINGs, they will likely be sequential. Added a test that shows that for 100,000 timers, the time spent is now very small. 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>
