5b3ccfd95f Move people list rendering into SearchEngine
Summary:
Ref T4986. One note:

  - We have a separate "browse directory" capability, to provide some soft privacy for users of public installs. Respect that policy within the SearchEngine.
  - Also restore some other icons I missed earlier.

Test Plan:
  - Viewed people list.
  - Build people panel.
  - Verified people panel was just me without browse capability.

e6f6a58f93 Move activity log rendering to a dashboard panel
Summary:
Ref T4986. Swap this in. Two minor notes:

  - I adjusted the SearchEngine to add an additional constraint when the viewer isn't an admin. This mostly stops us from doing a bunch of unnecessary work.
  - I fixed the settings panel to paginate (currently loads all results, slow in production).

Test Plan: Viewed logs; viewed settings panel; created a dashboard panel.

6300955661 Dashboards - add layout mode to dashboards
Summary:
This gets us the ability to specify a "layout mode" and which column a panel should appear in at panel add time. Changing the layout mode from a multi column view to a single column view or vice versa will reset all panels to the left most column.

You can also drag and drop where columns appear via the "arrange" mode.

We also have a new dashboard create flow. Create dashboard -> arrange mode. (As opposed to view mode.) This could all possibly use massaging.

Fixes T4996.

Test Plan:
made a dashboard with panels in multiple columns. verified correct widths for various layout modes

re-arranged collumns like whoa.

7ab26aef66 Internet Explorer compatibility fixes
Summary:
A few fixes for IE that makes this work in IE9+ and at least you can drag things and have it fail horribly in IE8 now. Ref T5023.

 - try / catch around getBoundingClientRect because IE throws if the object is not attached to the DOM. The correct value can be inferred in these cases as 0,0
 - turns out IE has different values for button here (1,2,4) than other browsers. special case this by using the other IE fact that 'which' will be null

Test Plan: dragged and dropped tasks successfully in IE9, IE10, and IE11 on Windows 7. dragged and dropped tasks unsuccessfully in IE8 on Windows 7 - they always "drop" to the 2nd position or so as I think the ondrag code isn't firing properly or something

347252fda8 Improve clarity of commit and symbol handling in DiffusionRequest
Summary:
Ref T2683. Currently, DiffusionRequest has four different "commitey" things:

  - `commit`
  - `rawCommit`
  - `symbolicCommit`
  - `stableCommit`

Of these, only two are actually distinct, useful values: `symbolicCommit` (which holds the value the request originally contained, if one existed) and `stableCommit` (which resolves that value, or the value implied by its omission, into a stable, permanent commit identifier).

  - `rawCommit` is equivalent to `symbolicCommit` and can be simply removed.
  - `commit` has some sketchy magic around it that needs to be pulled out before it can be jettisoned.

Summary:
Ref T2683. At least locally, browse views are now nearly instantaneous, even in Mercurial. We also fall back to what we were doing before if we miss or take too long, so this shouldn't make things very much worse even in extreme cases.

For a local `hg` repo, the time we spend pulling browse stuff has dropped from ~3,000ms to ~20ms. This is probably atypical, but not completely crazy or rigged or anything.

df59f4b047 Batch all supplementary information in Diffusion browse views
Summary: Ref T2683. Instead of sending one request for each path's history, send one request for all of it. This permits optimizations which are not currently available to us. It degrades the user experience a tiny bit in theory, but on my machine it's actually way faster already.

Test Plan: Loaded a browse page.

ac020bc420 Implement a lint count query
Summary: Ref T2683. This query is currently unbatched and happens inside a view. Leave it inside the view for now, but separate it and make it batchable.

e4ea092f60 Implement a chunked, APC-backed graph cache
Summary:
Ref T2683. This is a refinement and simplification of D5257. In particular:

  - D5257 only cached the commit chain, not path changes. This meant that we had to go issue an awkward query (which was slow on Facebook's install) periodically while reading the cache. This was reasonable locally but killed performance at FB scale. Instead, we can include path information in the cache. It is very rare that this is large except in Subversion, and we do not need to use this cache in Subversion. In other VCSes, the scale of this data is quite small (a handful of bytes per commit on average).
  - D5257 required a large, slow offline computation step. This relies on D9044 to populate parent data so we can build the cache online at will, and let it expire with normal LRU/LFU/whatever semantics. We need this parent data for other reasons anyway.
  - D5257 separated graph chunks per-repository. This change assumes we'll be able to pull stuff from APC most of the time and that the cost of switching chunks is not very large, so we can just build one chunk cache across all repositories. This allows the cache to be simpler.
  - D5257 needed an offline cache, and used a unique cache structure. Since this one can be built online it can mostly use normal cache code.
  - This also supports online appends to the cache.
  - Finally, this has a timeout to guarantee a ceiling on the worst case: the worst case is something like a query for a file that has never existed, in a repository which receives exactly 1 commit every time other repositories receive 4095 commits, on a cold cache. If we hit cases like this we can bail after warming the cache up a bit and fall back to asking the VCS for an answer.

This cache isn't perfect, but I believe it will give us substantial gains in the average case. It can often satisfy "average-looking" queries in 4-8ms, and pathological-ish queries in 20ms on my machine; `hg` usually can't even start up in less than 100ms. The major thing that's attractive about this approach is that it does not require anything external or complicated, and will "just work", even producing reasonble improvements for users without APC.

In followups, I'll modify queries to use this cache and see if it holds up in more realistic workloads.

Test Plan:
  - Used `bin/repository cache` to examine the behavior of this cache.
  - Did some profiling/testing from the web UI using `debug.php`.
  - This //appears// to provide a reasonable fast way to issue this query very quickly in the average case, without the various issues that plagued D5257.
