        * include/ns.h:
        * nsd/nsd.h:
        * nsd/init.c:
        * nsd/proc.c:
        * nsd/cache.c: Global hash of cache names removed; access no
        longer available via Ns_CacheFind() or ns_cache_names.  Caches
        have unique locking requirements and lifetimes which could be
        violated by e.g. running ns_cache_stats on a thread local cache as the
        thread is exiting.

        New Ns_CacheCreateEx() allows creating a cache which has both a
        size and a time limit.

        Caches with time limits are calculated differently.  Previous
        behaviour was to periodically check the last access time of each
        cache entry and flush those which had expired.  A busy cache could
        grow without bound.  New behaviour is to check for expirey each time
        an entry is retrieved from the cache.  All caches can (and should)
        be size limited.  Timeouts may be specified per cache and per
        entry using new Ns_CacheSetValueExpires().

        Ns_CacheFlush() now returns the number of entries flushed.

        New Ns_CacheStats() takes over from ns_cache_stats for non-Tcl
        caches. Stats are returned in Tcl "array get" format.

        Removed Ns_CacheMalloc(), Ns_CacheFree() and Ns_CacheName().

        Move Tcl commands to tclcache.c.

        * nsd/Makefile:
        * nsd/tclcmds.c:
        * nsd/tclcache.c:
        * tests/ns_cache.test: Add new Tcl commands ns_cache_create,
        _eval, _append, _lappend, and _incr. (RFE# 1119257)

        Old commands ns_cache_names, _keys, _flush and _stats now only
        work on Tcl caches.  ns_cache_size has been removed; the size is
        now reported along with other statistics. These commands now only
        work on Tcl caches.

        * tcl/cache.tcl: New ns_memoize and related commands which act
        just like ns_cache_eval but use the script as a key into the
        memoize cache.
