Provide hasChildren() to replace isEmptyContent()

Summary:
Fixes T3698. Sometimes views need to render differently depending on whether they contain content or not. The existing approach for this is `isEmptyContent()`, which doesn't work well and is sort of hacky (it implies double-rendering content, which is not always free or side-effect free).

Instead, provide a test for an element without children. This test is powerful enough to catch the easy cases of `null`, etc., and just do the expected thing, but will not catch a View which is reduced upon rendering. Since this is rare and we have no actual need for it today, just accept that as a limitation.

Test Plan:
Viewed Timeline and Feed UI examples. Viewed Feed (feed), Pholio (timelineview), and Differential (old transactionview).

Stop using process/filesystem-based checks to determine if daemons are running

Summary:
We currently check if daemons are running using the filesystem and process list. These checks reach the wrong result for a lot of users because their webservers can't read the filesystem or process list. They also reach the wrong result for daemons running on other machines.

Instead, query the active daemon list to see if daemons are running. This should be significantly more reliable.

(We didn't do this before because the running daemon list mechanism didn't exist when the check was written, and at the time it was more complex than doing a simple filesystem/process list thing.)

Test Plan: Viewed `/repositories/` with and without daemons running, saw appropriate warning or lack of warning.

Don't synchronize Asana objects with no CCs and no responsible, non-author users

Summary: Ref T2852. Currently, we publish commits with no audit requests and reviews with no CCs or reviewers into Asana. This creates undesired notifications, so drop events which would publish an object that doesn't exist yet and has no followers or respible users.

Test Plan: Used `bin/feed republish` to publish a story about an object with no related users, saw the publish abort with the new message. Added a CC, published again, got a publish.

Allow Pholio mock images to be drag-reordered

Raise a setup fatal for 'disable_functions' or 'disable_classes'

Summary:
Fixes T3709. PHP has two configuration options ('disable_functions', 'disable_classes') which allow functions and classes to be blacklisted at runtime.

Since these break things in an unclear way, raise a setup fatal if they are set.

We take a slightly more tailored approach to these in `phd` already, but I'd rather try just saying "no, this is bad" and see if we can get away with it. I suspect we can, and there's no legitimate reason to blacklist functions given that Phabricator must have access to, e.g., `proc_open()`.
