ba2984bf2b dmllib: more consistent err handling for execute_sql() and others 
Silent errors in execute_sql() have been causing us lots of grief.
Turns out that if you have dblogerror set, it _will_ write it to the
logs.

DMLlib wasn't consistent. Most "modern" codepaths were calling both
debugging() and the dblogerror idiom. So we make all calls to
$db->Execute() consistent.

(Some exceptions remain, mostly for hardcoded SQL, such as the SET
statements when we connect...)

c96a4a46d5 rcache_* calls - flesh out logic and use $MCACHE if available 
- move from $CFG->enablerecordcache <count> to $CFG->rcache <type>

 - if $CFG->rcache === 'internal' use the cache array
   otherwise, attempt to use $MCACHE

 - implement and use rcache_getforfill() to catch thundering herds

 - the cache lifetime is hardcoded to 2s until we understand better the
   possible race conditions against updates that are not happening via
   update_record() / delete_record()

6c2f585f85 dmllib: introducing the rcache_* functions for record cache handling 
Abstracted Sam's initial work with $record_cache into a series of functions
that abstract things _just enough_ that we can use an internal
in-memory-array implementation or something that is shared across
processes, like memcached or the turckmmcache/eaccelerator caches.

Also
- added hit/miss stats tracking and reporting
- removed max entries limiting as it was buggy - var names mismatches
  and not counting unset()s
