Version 1.3.20:
- Various small fixes
- Introduce explicit plugin function prototypes to meet the C23 standard
  that more strictly check if the function prototype matches the actual
  argument list. Move these prototypes to lcas_types.h.
- Remove unused LCMAPS_MOD_HOME
- Initialize plugin_procs array
- Remove ineffective tests for NULL array member of struct

Version 1.3.19:

Bugfix:
- plugins where not properly dlclose()-ed. This indirectly triggered a
  segmentation fault in gsisshd when used in combination with PAM.

Version 1.3.17:

Bugfix:
- lcas_findfile() was fixed for plugins, but also used for db file in
  lcas-plugins-basic. Functionality is now split

Version 1.3.16:

Bugfix:
- Fix gsi handling code to prevent clash with globus symbols.

Version 1.3.15:

Run time feature:
- New plugin search code, similar to the LCMAPS approach.
    1. Try to set get the environment variable LCAS_MODULES_DIR.
    2. On success: check if the provided plugin filename has an absolute path already,
		   if not, prepend the $LCAS_MODULES_DIR value to the plugin and
		       check if the file exists.
                           if no file exists continue with 3.
       On failure: goto 3.
    3. Check if the provided plugin filename has an absolute path already,
	    if not, prepend the LCAS_MOD_HOME #define value to the plugin path
		and check if the file exists.
		Use the LCAS_MOD_HOME #define. The defined value originates from
		the configure script and 
		could be set there to the default or the
		--with-lcas-moduledir=DIR option.
            if this keeps failing, exit and trigger an LCAS initialization error.
    
    A new log line is printed in the log file to indicate what the LCAS plugin
    search paths are.

Build time feature:
- New configure option: --with-lcas-moduledir=DIR
  Sets the default search directory for LCAS modules to this value.
  Without the setting the default is relative to the (build) systems $libdir
  value: /usr/local/lib/lcas


Version 1.3.13:

This version of LCAS and the related LCAS plugins introduces the following new features:
- fix a few minor segfault situations.
- Log file output is cleaned up a bit

- The LCAS framework and LCAS-Interface components are now integrated in each other
- adjusted to be able to use EPEL, EMI and gLite packages
AS_MOD_HOME
