When `RM_ZsetAdd()`/`RM_ZsetIncrby()`/`RM_StreamAdd()` fails, if a new key happens to
be created using `moduleCreateEmptyKey()`, we should clean up the empty key.
## Test
1) Add new module commands(`zset.add` and `zset.incrby`) to cover `RM_ZsetAdd()`/`RM_ZsetIncrby()`.
2) Add a large-memory test to cover `RM_StreamAdd()`.
Summary of changes:
1. Rename `redisCommand->name` to `redisCommand->declared_name`, it is a
const char * for native commands and SDS for module commands.
2. Store the [sub]command fullname in `redisCommand->fullname` (sds).
3. List subcommands in `ACL CAT`
4. List subcommands in `COMMAND LIST`
5. `moduleUnregisterCommands` now will also free the module subcommands.
6. RM_GetCurrentCommandName returns full command name
Other changes:
1. Add `addReplyErrorArity` and `addReplyErrorExpireTime`
2. Remove `getFullCommandName` function that now is useless.
3. Some cleanups about `fullname` since now it is SDS.
4. Delete `populateSingleCommand` function from server.h that is useless.
5. Added tests to cover this change.
6. Add some module unload tests and fix the leaks
7. Make error messages uniform, make sure they always contain the full command
name and that it's quoted.
7. Fixes some typos

APIs added for these stream operations: add, delete, iterate and
trim (by ID or maxlength). The functions are prefixed by RM_Stream.
* RM_StreamAdd
* RM_StreamDelete
* RM_StreamIteratorStart
* RM_StreamIteratorStop
* RM_StreamIteratorNextID
* RM_StreamIteratorNextField
* RM_StreamIteratorDelete
* RM_StreamTrimByLength
* RM_StreamTrimByID
The type RedisModuleStreamID is added and functions for converting
from and to RedisModuleString.
* RM_CreateStringFromStreamID
* RM_StringToStreamID
Whenever the stream functions return REDISMODULE_ERR, errno is set to
provide additional error information.
Refactoring: The zset iterator fields in the RedisModuleKey struct
are wrapped in a union, to allow the same space to be used for type-
specific info for streams and allow future use for other key types.
