fix(build): Use gai_strerrorA not gai_strerror on Windows

Browse Source 
* Explicitly call gai_strerrorA (for Windows builds), so that the code work correctly in 32bit or 64bit builds.

* Implement GAI_STRERROR macro to deal with Windows vs. Non-Windows compiles for 64-bit.

* make usocket.c consistent with other modules that call macro GAI_STRERROR

* Use different name not just different case for macro wrapping function
