plugins FEATURE load external plugins as part of plugins initiation
Use default plugins directories or the directories provided via
environment variable and besides the internal types and extensions
plugins load also the plugins available in those directories.
The default directories (<INSTALL LIBDIR>/libyang/extensions and <INSTALL
LIBDIR>/libyang/types byt default) can be set using cmake and then they
are available via a new configuration header cmake_config.h. Also some
other cmake information regarding the plugins are placed there.
