Major plugin refactor and cleanup.

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.

+# 3/ Start the cygserver: nohup /usr/sbin/cygserver &
+# 4/ close the separate terminal
+# 5/ run the Foundation tests: build/script/runtests.sh Foundation
