Switched to POCO library for unified platform/library interface. Deprecated the external module API. It was creating more problems than solving. Removed most built-in libraries in favor of system libraries for easier maintenance. Cleaned and secured code with help from static analyzers.

|
|
/// before defaultClientContext() or defaultServerContext() are called.
|
|
///
|
|
/// If defaultClientContext() and defaultServerContext() are never called
|
|
/// in an application, initialization of SSLManager can be omitted.
