There's alsoan unused mutex.Split global stats into `stats` and `stats_state`. initialize via memset,reset only `stats` via memset, removing several places where stats values getrepeated. Looks much cleaner and should be less error prone.

An ascii multiget one make one log lineper key fetched.It's a good place to start. Need to come back and refactor parts of logger.cagain, then convert all prints in the codebase to log entries.

A new background thread aggregates thelogs, further processes them, then writes them to any "watchers".Logs can have the time added to them, and all have a GID so they can be putback into strict order.This is an early preview. Code needs refactoring and a more complete set ofoptions. All watchers are also stuck viewing the global feed of logs, even ifthey asked for different data.As of this commit there's no way to toggle the "stderr" watcher.

Pages can be re-assigned out of that pool during allocation.Combined with item rescuing from the previous patch, we can safely shufflepages back to the reassignment pool as chunks free up naturally. This shouldbe a safe default going forward. Users should be able to decide to free ormove pages based on eviction pressure as well. This is coming up in anothercommit.This also fixes a calculation of the NOEXP LRU size, and completely removesthe old slab automover thread. Slab automove decisions will now be part of thelru maintainer thread.

Now, if an item is valid and free chunks are available in the sameslab class, copy the item over and replace it.It's up to external systems to try to ensure free chunks are available beforemoving a slab page. If there is no memory it will simply evict them as normal.Also adds counters so we can finally tell how often these cases happen.
