Remove unnecessary allocation for EXT_SIZE (1024 bytes) in
taosHashGetCloneExt. By reading the code, this doesn't seem like
needed.

* Testing
./taosdemo

Spent 87.4217 seconds to insert rows: 100000000, affected rows: 100000000 with 8 thread(s) into test.meters. 1143880.49 records/second

insert delay, avg:      69.22ms, max:     240.04ms, min:      26.19ms

Add wrapper for per entry lock / unlock.

Unify hash table lock function namespace and does not have
functional change.

Remove unused "freeFp".

Use the right format specifier (%zu) to print size_t type.

Simplify implementation of taosHashTableResize. Remove unnecessary
while loop.

1. Add missing lock / unlock in profiling code. Without
   synchronization, the profiling code could access freed memory.
2. Remove unnecessary assert.
3. Remove unncessary if check in taosHashRemoveWithData.

Fix a memory leak bug introduced in [5/n].

1. Simplify implementation of taosHashCondTraverse
2. Complete function header comments for a few more functions

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
