1. Minor refactoring of taosHashInit
2. Complete error handling path of taosHashInit

* Testing
compile tdengine
cmake .. && cmake --build .

A few cleanups:
1. Move implementation details (macro definition, SHashEntry and SHashObj
   definition) to hash.c. Only leave relevant APIs in hash.h.
2. Complete function header comments.
3. Correct variable naming from "newSize" to "newCapacity".

A few cleanups:
1. Rename hash node "count" to "refCount" for ease of reading
2. Trailing white space removal of hash.h

A few cleanups for the hashtable implementation:
1. Correct function header comments
2. Complete argument checking for a few functions
3. Remove trailing space
