10274	Simplify options caching	ryan	ryan	"Instead of caching all options and their values to a big array, let's cache only the option names to an array and cache the values individually. The option name cache will be passed to wp_cache_get_multi() (which needs to be added) at startup to prime the option cache. Here's the flow.

(List of option names cached to all_options)

First page load:

 * wp_cache_get all_options
 * Nothing is cached to all_options, so query db for all option names and values
 * Loop over DB results, wp_cache_add each option and construct all_options list.
 * wp_cache_set all_options with the options list * Cache for each option is now primed via the wp_cache_adds.

Next page load:

 * wp_get_get all_options
 * all_options has cached list of option names, pass those names to wp_cache_get_multi
 * get_multi does one memcached request for all options
 * cache is now primed for all options, each option in its own bucket, no need to query DB "	defect (bug)	closed	low	2.9	Cache		minor	worksforme
