Summary:
We lock tasks by setting `leaseOwner` to a unique value, but the value is currently unique-to-the-process rather than unique-to-the-query. This means that if a process leases a task, then leases another task, both tasks will have the same `leaseOwner`. This can cause an issue where we go to select the task we just leased and get the other task instead, if we aren't careful about the select construction.
We can avoid this by being clever and making sure the select is constructed correctly, but making the `leaseOwner` unique to the query is much simpler and more foolproof. This guarantees we always select only the rows we just leased.
Also remove `PhabricatorGoodForNothingWorker` since `PhabricatorTestWorker` fills its role of allowing things to be tested, and simplify the unit tests since we don't need to be clever about avoiding this issue any more.
Test Plan: Ran unit tests.

Differential Revision: https://secure.phabricator.com/D3862
Summary:
This was the major goal of D3859/D3855, and to a lesser degree D3854/D3852.
As Drydock is allocating a resource, it may need to allocate other resources first. For example, if it's allocating a working copy, it may need to allocate a host first.
Currently, we have the process basically queue up the allocation (insert a task into the queue) and sleep() until it finishes. This is problematic for a bunch of reasons, but the major one is that if allocation takes more resources (host, port, machine, DNS) than you have daemons, they could all end up sleeping and waiting for some other daemon to do their work. This is really stupid. Even if you only take up some of them, you're spending slots sleeping when you could be doing useful work.
To partially get around this and make the CLI experience less dumb, there's this goofy `synchronous` flag that gets passed around everywhere and pushes the workflow through a pile of special cases. Basically the `synchronous` flag causes us to do everything in-process. But this is dumb too because we'd rather do things in parallel if we can, and we have to have a lot of special case code to make it work at all.
Get rid of all of this. Instead of sleep()ing, try to work on the tasks that need to be worked on. If another daemon grabbed them already that's fine, but in the worst case we just gracefully degrade and do everything in process. So we get the best of both worlds: if we have parallelizable tasks and free daemons, things will execute in parallel. If we have nonparallelizable tasks or no free daemons, things will execute in process.
Test Plan: Ran `drydock_control.php --trace` and saw it perform cascading allocations without sleeping or special casing.

Currently, when taskmasters complete a task it is immediately deleted. This prevents us from doing some general things, like:
- Supporting the idea of permanent failure (e.g., after N failures just stop trying).

Having better visibility into this is important to Drydock, which builds on the task system. Also, generally buff debug output for task execution.

Summary:
Provides a simple way for policy-aware queries to pre-filter results without needing to maintain separate cursors, and fixes a bunch of filter-related edge cases.
- For reverse-paged cursor queries, we previously reversed each individual set of results. If the final result set is built out of multiple pages, it's in the wrong order overall, with each page in the correct order in sequence. Instead, reverse everything at the end. This also simplifies construction of queries.
- `AphrontCursorPagerView` would always render a "<< First" link when paging backward, even if we were on the first page of results.
- Add a filtering hook to let queries perform in-application pre-policy filtering as simply as possible (i.e., without maintaing their own cursors over the result sets).
Test Plan: Made feed randomly prefilter half the results, and paged forward and backward. Observed correct result ordering, pagination, and next/previous links.

Two high-level things happening here:
- We no longer ever need to put meta-UI (content creation, editing, notices, etc.) on live blog views, since this is all in Phame now. I pulled this out.
- On the other hand, I pushed more routing/control logic into Skins and made the root skin a Controller instead of a View. This simplifies some of the code above skins, and the theory behind this is that it gives us greater flexibility to, e.g., put a glue layer between Phame and Wordpress templates or whatever else, and allows skins to handle routing and thus add pages like "About" or "Bio".
- I added a basic skin below the root skin which is more like the old root skin and has standard rendering hooks.
- "Ten Eleven" is a play on the popular (default?) Wordpress themes called "Twenty Ten", "Twenty Eleven" and "Twenty Twelve".

Summary:
This leaves the UI in a pretty rough state, but implements blog policy controls and queries, and 1:1 relationships between posts and blogs. Needs a bunch more cleanup but seemed like an okayish breaking point in terms of cohesiveness.
Posts have these rules:
- Drafts are visible only to the author.
- Published posts are visible to anyone who can see the blog they appear on.
- Posts are only editable by the author.
...so we don't need any special policy UI or state to accommodate these rules.
Posts may have no blog if they're grandfathered in or you write a post to a blog and then lose the ability to see the blog. This is the messiest edge case -- specifically:
- You write a post to blog A.
- You publish the post.
- I edit the "Visible To:" for blog A and set it to exclude you.
What we do in this case is let you see the post in "My Posts", but you can no longer see the blog and you'll see the post as not being part of a blog. We can maybe give you some UI to let you move it later or something.
Test Plan: Hit all (I think?) of the interfaces without issues. Definitely some UI problems still right now.

There are several cases where we load data like:

This idiom seems fairly useful and non-dangerous, so I made `loadFromArray()` just drop extra keys.
