from the four main SQL tables in realtime, which
effectively gives us "live" SQL.
Changed eventfd pipe engine to not use buffered write.
Added TryLock to threading engines.
Made blocking SQL queries in our SQL API thread-safe.
Added a search path option to the Config script for cmake to use when finding libraries for modules or for gettext.
Fixed m_mysql and m_ssl to work under Windows, made the Windows Config
program remember the last used options, and fixed Windows release builds.
This allows modules (xmlrpc) to create and accept SSL connections.
Also fixed unloading m_mysql at certain times and made the threading
engine always work correctly on Windows.
