#647394 #514030 by PreZ, me: Rename classnames and globals to prevent colissions, also fixes for code-style by coder module.

-Spent the past couple days tweaking the SHIT out of everything.
-Updated cacherouter.inc to work more like core cache.inc.
-Got all engines (except for the new memcached.inc) passing tests.
-Fixed XCache to not whites screen any more and actually work.
-Fixed eacc to actually work (and not bad I must say).  You MUST use the svn snapshot of eAccelerator for this to clear cache correctly.
tweaked apc/eacc/xcache to use files for locks for better reliability and true atomic locks.
-Fixed a ton of bugs.
-Ripped out stats.  STATS WILL NOT GO INTO 1.0.  Sorry guys, it's just not gonna happen.

I'm marking this as RC1.  Session handling and stats will go into 2.0.

Fix for expire to obey core expire better for memcache and apc.  Need to roll these changes into xcache + eacc + memcached still after some testing.

Fix for issue #266588 by Jonah Ellison and andypost.  Great ideas, thank you  times 10^6. ;)  I think this is a great solution.

I suppose this only really fixes shared memcache, and we should implement a fix for "CACHE_PERMANENT" stuff.  But what exactly is the point of CACHE_PERMANENT again?? Caches are volatile by nature imho.

Update our cookie to be the same as the boost cookie.  No need for two cookies to do the exact same thing.

If database engine is used, we can now actually serve pages directly with page_cache_fastpath.  This is an improvement over core and makes db engine worth using.  Thanks to Jonah Ellison of authcache for the idea.  Now we should be able to make these modules work together.

Added memcached engine based on initial cut by joshk.  Still a lot to do to make this engine fully utilize the power of the libmemcache library.  Should be much better (in theory) than memcache engine.  Thanks Josh for getting the ball rolling.

Fix for [#418764] by mundanity, TBarregren: cache_clear_all() in cacherouter.inc.  What the fuck??  I am surprised that I have gone this long without finding this bug.  Big ups to everyone for this one.

Fix for issue #341575 by janicel700, andypost and greg.harvey: XCache causes white screen of death.  Thanks guys!

Thank you!

Refactor cache creation and initialization to be better suited for programmatic cache creation.  Initial patch by Damien Tournoud.

Fix for issue #365065

Cleaned up patch a bit and kept file patches from earlier.

Thank you!

Fix for issue #475788: File engine - Cache write error presented to users. Should log by default and only display for Administrators.

I liked it so much I switched everything to watchdog logging.

Thanks harking!

Fixes issue #463758: Change module package in info file.  Thank you psynaptic!
