1. move gnu compile flags "-pipe -Wshadow" from root "CMakeLists.txt" to "cmake/define.inc"; and change compile flag "/O3" to "/O2", because "/O3" is not supported by MSVC.
2. fix compile warnings in "src/util/src/tbuffer.c", by using "union" to transform integer with float and double.
3. use "memcpy()" instead of directly type convert in "rc/util/src/tutil.c" to resolve memory alignment problem in ARM platform.
4. reduce other compile warnings.

1. rename semphone to semaphore
2. add comment for tsched.h
3. change the function signature for taosSchedulerTask, changing from
return int to void. We currently don't check any return code of the function.
4. add some error handlings. For fatal error, just exit the process because
the program may run into a random state.
