http://drupal.org/cvs?commit=79316 clear cache on install

Lots of bugfixes. Thanks to killes, chx and LifetimeTV for the great testing and help getting this module enterprise-ready.

• make sure $cache->data is object. Reported by chx.
• Many bugfixes regarding the debug information and its interactions with bootstrap.
• typo in .info file: depends => dependencies

• Added admin/settings/memcache page to turn per-page memcache statistics on or off globally.
• Removed user_access call from hook_init... that function isn't available in the init phase of bootstrapping.
• rearranging and consolidating. memcache.module is now just a placeholder for its install hooks. To guarantee that it gets turned on, the memcache_admin module does indeed depend on it. All stats collecting is now in memcache_admin. The previous memcache_admin status page is now under admin/logs. There is a new admin/settings page for memcache to turn display of per-page stats on or off.
• updated documentation.
• #163277 by RobRoy use MEMCACHE_COMPRESSED instead of TRUE to flag compression.
• removing session files again. They accidentally jumped into the 1.3 release without my permission.

Fixing a critical SQL error in memcache.db.inc. Reported by robertDouglass and corrected by chx. Also adds hook_requirements.

Critical error in memcache_admin code introduced in 1.1 release.

• adding separate patches for Drupal 5.1 and 5.2
• admin module now working pretty well. Many unimplemented features, and some nice fancy graphics would be cool as well, but it shows up in the menu and gives you the raw stats for the various servers.
• correct menu type in admin module so that link shows in menu
• #158140 updating docs and removing old tests. New tests should be written to reflect newest code
• #149120 by Shiny - postgresql fixes
• #162710 reroll patch for DRUPAL-5-2

1. documenting the 'memcache_key_prefix' variable that can be set in if more than one Drupal instance is to share memcache
2. rob discovers hook_devel_cache and promptly simplifies the install and uninstall hooks for memcache.
3. Adding a TROUBLESHOOTING section to README.txt
4. session handling doesn't work right. I'm removing it for now in advance of a 1.0 release
5. #154247 by chx and robertDouglass: clone objects going into memcache
6. #154287 by chx: no table locking

This is the first public (beta) release of the Memcache module. The admin stats still need a lot of work and patches are welcome. The basic machinery should be working well, however. Installation documentation needs some love.

This code is exactly the same as the development snapshot that has been available until now. Future development will be changing the overall strategy with regards to the relation between memcache and Drupal's own cache mechanism, so this version is being released only to be available for anyone who may be using it currently.

BETA CODE. This code is here for testing and community input. Patches should apply to DRUPAL-5.
