This header file includes the SilcClientEntry, SilcChannelEntry and
 SilcServer entry structures and various routines to search, resolve and
 handle these structures.

 All entries (SilcClientEntry, SilcChannelEntry and SilcServerEntry) are
 reference counted.  If application wishes to save an entry pointer it must
 always first acquire a reference.  The reference must be released once the
 entry is not needed anymore.  If application wants to read any data from
 the entry structure it must first lock the entry.  This protects access to
 the entries in multithreaded environment.  If threads are not used, locking
 the entries is not needed.  They however still must be referenced even
 when threads are not used.
