Added a log of the keyname in the test modules to reproduce the problem (tests crash without the fix)

All the defrag allocations API expects to get a value and replace it, leaving the old value untouchable. In some cases a value might be shared between multiple keys, in such cases we can not simply replace it when the defrag callback is called. To allow support such use cases, the PR adds two new API's to the defrag API: 1. `RM_DefragAllocRaw` - allocate memory base on a given size. 2. `RM_DefragFreeRaw` - Free the given pointer. Those API's avoid using tcache so they operate just like `RM_DefragAlloc` but allows the user to split the allocation and the memory free operations into two stages and control when those happen. In addition the PR adds new API to allow the module to receive notifications when defrag start and end: `RM_RegisterDefragCallbacks` Those callbacks are the same as `RM_RegisterDefragFunc` but promised to be called and the start and the end of the defrag process.

* Support BUILD_TLS=module to be loaded as a module via config file or command line. e.g. redis-server --loadmodule redis-tls.so * Updates to redismodule.h to allow it to be used side by side with server.h by defining REDISMODULE_CORE_MODULE * Changes to server.h, redismodule.h and module.c to avoid repeated type declarations (gcc 4.8 doesn't like these) * Add a mechanism for non-ABI neutral modules (ones who include server.h) to refuse loading if they detect not being built together with redis (release.c) * Fix wrong signature of RedisModuleDefragFunc, this could break compilation of a module, but not the ABI * Move initialization of listeners in server.c to be after loading the modules * Config TLS after initialization of listeners * Init cluster after initialization of listeners * Add TLS module to CI * Fix a test suite race conditions: Now that the listeners are initialized later, it's not sufficient to wait for the PID message in the log, we need to wait for the "Server Initialized" message. * Fix issues with moduleconfigs test as a result from start_server waiting for "Server Initialized" * Fix issues with modules/infra test as a result of an additional module present Notes about Sentinel: Sentinel can't really rely on the tls module, since it uses hiredis to initiate connections and depends on OpenSSL (won't be able to use any other connection modules for that), so it was decided that when TLS is built as a module, sentinel does not support TLS at all. This means that it keeps using redis_tls_ctx and redis_tls_client_ctx directly. Example code of config in redis-tls.so(may be use in the future): RedisModuleString *tls_cfg = NULL; void tlsInfo(RedisModuleInfoCtx *ctx, int for_crash_report) { UNUSED(for_crash_report); RedisModule_InfoAddSection(ctx, ""); RedisModule_InfoAddFieldLongLong(ctx, "var", 42); } int tlsCommand(RedisModuleCtx *ctx, RedisModuleString **argv, int argc) { if (argc != 2) return RedisModule_WrongArity(ctx); return RedisModule_ReplyWithString(ctx, argv[1]); } RedisModuleString *getStringConfigCommand(const char *name, void *privdata) { REDISMODULE_NOT_USED(name); REDISMODULE_NOT_USED(privdata); return tls_cfg; } int setStringConfigCommand(const char *name, RedisModuleString *new, void *privdata, RedisModuleString **err) { REDISMODULE_NOT_USED(name); REDISMODULE_NOT_USED(err); REDISMODULE_NOT_USED(privdata); if (tls_cfg) RedisModule_FreeString(NULL, tls_cfg); RedisModule_RetainString(NULL, new); tls_cfg = new; return REDISMODULE_OK; } int RedisModule_OnLoad(void *ctx, RedisModuleString **argv, int argc) { .... if (RedisModule_CreateCommand(ctx,"tls",tlsCommand,"",0,0,0) == REDISMODULE_ERR) return REDISMODULE_ERR; if (RedisModule_RegisterStringConfig(ctx, "cfg", "", REDISMODULE_CONFIG_DEFAULT, getStringConfigCommand, setStringConfigCommand, NULL, NULL) == REDISMODULE_ERR) return REDISMODULE_ERR; if (RedisModule_LoadConfigs(ctx) == REDISMODULE_ERR) { if (tls_cfg) { RedisModule_FreeString(ctx, tls_cfg); tls_cfg = NULL; } return REDISMODULE_ERR; } ... } Co-authored-by:zhenwei pi <pizhenwei@bytedance.com> Signed-off-by:

Create new module type enhanced callbacks: mem_usage2, free_effort2, unlink2, copy2. These will be given a context point from which the module can obtain the key name and database id. In addition the digest and defrag context can now be used to obtain the key name and database id.

With this fix, module data type registration will fail if the load or save callbacks are not defined, or the optional aux load and save callbacks are not either both defined or both missing.

Add a new set of defrag functions that take a defrag context and allow defragmenting memory blocks and RedisModuleStrings. Modules can register a defrag callback which will be invoked when the defrag process handles globals. Modules with custom data types can also register a datatype-specific defrag callback which is invoked for keys that require defragmentation. The callback and associated functions support both one-step and multi-step options, depending on the complexity of the key as exposed by the free_effort callback.
