Ticket History #3716: Plugin search algorithm should take lists of name and directories

The support library plugin interface should take lists of plugin names and directories to search
for plugins in. Since the plugin names will not usually have the platform specific extension, the
support library should also have an API to form a larger list of plugin names with the possible
platform specific extensions added.

Changed to krb5int_open_plugin_dirs/krb5int_close_plugin_dirs which
takes a list of filebases and directories rather than a list of full paths
so the caller doesn't have to generate the possibilities themselves.
krb5int_open_plugin_dirs will append the possible suffixes for that platform
(including no suffix in case there already is one on the file base).

Modified the kdb and locate kdc interfaces to use the new API.
