Add support to HASH and SET datatypes

[moticless]

Following this PR, the parser will be able to parse HASH and SET data types.

• This includes: plain hash, ziplist hash, listpack hash, zipmap hash, plain set, intset and listpack set.
• Added corresponding tests for json, resp and redis formaters.
• Data integrity doesn't check for duplication of elements that was read from RDB (if it is important to client, then it is the one to implement it).
• Added corresponding tests for json, resp and redis formaters.
• As list data-type also uses ziplist and listpack - some refactor was made at parserRaw.c.
• Copied implementation of zipmap from Redis to deps/redis/zipmap.c

How to review:

• librdb-api.h
• tests: review the filenames. Review the json files to see the expected output.
• Please review core parser code (parser.c and parserRaw.c)

Another commit:
fixed BulkInfo pointers invalidation due to realloc() by BulkAlloc.c. The fix is to avoid any realloc() and use simple list instead. To review it, see bulkAlloc.c

that's a lot of code and no description.
please fill it and let me know what to focus on.
