Fix issue of conversion from size_t to int

Browse Source 
ssl_helpers.c is treated with W3 warning level in MSVC complier.
So that it's reported as error for warning of conversion from
size_t to int. This change fixes all this type of warning seen in
Microsoft Visual Studio 12.0. Besides, some potential problems of
type conversion are also handled.
