code cleanup: we prefer 'CURLcode result'

Browse source 
... for the local variable name in functions holding the return
code. Using the same name universally makes code easier to read and
follow.

Also, unify code for checking for CURLcode errors with:

 if(result) or if(!result)

instead of

 if(result == CURLE_OK), if(CURLE_OK == result) or if(result != CURLE_OK)
