ec145b73fc Major refactoring of queue handlers to support running multiple sites in one daemon.
Key changes:
* Initialization code moved from common.php to StatusNet class;
  can now switch configurations during runtime.
* As a consequence, configuration files must now be idempotent...
  Be careful with constant, function or class definitions.
* Control structure for daemons/QueueManager/QueueHandler has been refactored;
  the run loop is now managed by IoMaster run via scripts/queuedaemon.php
  IoManager subclasses are woken to handle socket input or polling, and may
  cover multiple sites.
* Plugins can implement notice queue handlers more easily by registering a
  QueueHandler class; no more need to add a daemon.

The new QueueDaemon runs from scripts/queuedaemon.php:

* This replaces most of the old *handler.php scripts; they've been refactored
  to the bare handler classes.
* Spawns multiple child processes to spread load; defaults to CPU count on
  Linux and Mac OS X systems, or override with --threads=N
* When multithreaded, child processes are automatically respawned on failure.
* Threads gracefully shut down and restart when passing a soft memory limit
  (defaults to 90% of memory_limit), limiting damage from memory leaks.
* Support for UDP-based monitoring: http://www.gitorious.org/snqmon

Rough control flow diagram:
QueueDaemon -> IoMaster -> IoManager
                           QueueManager [listen or poll] -> QueueHandler
                           XmppManager [ping & keepalive]
                           XmppConfirmManager [poll updates]

Todo:

* Respawning features not currently available running single-threaded.
* When running single-site, configuration changes aren't picked up.
* New sites or config changes affecting queue subscriptions are not yet
  handled without a daemon restart.
* SNMP monitoring output to integrate with general tools (nagios, ganglia)
* Convert XMPP confirmation message sends to use stomp queue instead of polling
* Convert xmppdaemon.php to IoManager?
* Convert Twitter status, friends import polling daemons to IoManager
* Clean up some error reporting and failure modes
* May need to adjust queue priorities for best perf in backlog/flood cases

4cc9b183d7 Avoid spewing warnings about returning by reference on memcached cache misses by setting a var and returning it instead of trying to return false directly.
This hacky workaround is brought to you by DB_DataObject's PHP 4 roots.

85554d0840 Rearrange Memcached_DataObject::staticGet() to avoid "only variables can be passed by reference" warnings when DB lookup fails and we return false.
(We need to keep it returning a reference because the extlib parent class is stuck in PHP 4-land and uses references everywhere, including this function's return value. Yuck!)

Also changed pkeyGet to drop the reference, since it doesn't have an upstream equivalent.

b93244395f Fix for broken profile flag admin UI: delete stray flag entries when users are deleted so broken entries don't litter the lookups.
* added ProfileDeleteRelated event to match UserDeleteRelated, to allow plugins to add extra related tables on profile deletion
* UserFlagPlugin: deleting flags when target profile is deleted
* UserFlagPlugin: deleting flags when flagging user is deleted
* UserFlagPlugin: fix for autoloader -- class names are case-insensitive. We may get lowercase class names coming in at times, such as when creating DB objects programatically from a table name.

Note that any already-existing bogus entries need to be removed from the database:
select * from user_flag_profile where (select id from profile where id=profile_id) is null;
select * from user_flag_profile where (select id from user where id=user_id) is null;

eb22d2d240 Ticket 2135: trim overlong repeats with ellipsis rather than failing.
In web interface and retweet/repeat API we show the original untrimmed text, but some back-compat API messages will still show the trimmed 'RT' version.
This matches Twitter's behavior on overlong retweets, though we're outputting the RT version in more API results than they do.

aff78e5121 Cache fixes:
* We now cache negative lookups; clear them in Memcached_DataObject->insert()
* Mark file.url as a unique key in statusnet.ini so its negative lookups are cleared properly (first save of a notice with a new URL was failing due to double-insert)
* Now using serialization for default in-process cache instead of just saving objects; avoids potential corruption if you save an object to cache, change the original object, then fetch the same key from cache again

9e2e0605ed Move Authorization and Authentication plugin structures into core, instead of as plugins.
This move makes sense as you can addPlugin('Authentication') for example - these are abstract classes designed to be implemented, not used directly.

abc9b33241 Memcached_DataObject stores empty values in the cache
There's great value in knowing that something doesn't exist. We
now cache this information, and carefully compare the results from
cache as $results !== false instead of !empty($results), since some
empty values (null, 0, empty array, empty string) are stored in the
cache.

Caching staticGet() and pkeyGet() now store DB misses in the cache,
and cachedQuery() checks for empty results from the cache.

5a1ea0b9b2 Stop caching unfindable keys
There were some problems with the automated cache/uncache system
for data objects that made us cache unfindable keys (with null
attributes and sometimes null names). Fixed those problems and
refactored the encache() and decache() methods so they use a helper
to find the cache keys to use.
