Summary:
See PHI36. APCu originally had `apc_` methods, but at some point dropped these and only provides `apcu_` methods.
When the `apcu_` method is present, use it. It may not be present for older versions of APCu, so keep the fallback.
Test Plan:
- With modern APCu, clicked "Purge Caches" in Config > Caches.
- Before: fatal on bad `apc_clear_caches` call.
- After: Valid cache clear.

Summary: Ref T9640. APCu 5.0+ (for PHP7) uses `apcu_*` functions instead of `apc_` functions. Test for function existence and call the appropriate functions.

Summary:
Fixes T9874.
- Stop using the phrase "restart your webserver". Instead, say "restart Phabricator".
- Write a document explaining that "Restart Phabricator" means to restart all of the server processes, depending on how your configuration is set up, and approximately how to do that.
- Link to this document.
- In places where we are not specifically giving instructions and the user isn't expected to do anything, be intentionally vague so as to avoid being misleading.
Test Plan:
- Read document.
- Hit "exetnsion" and "PHP config" setup checks, got "restart Phabricator" with documentation links in both cases.

Summary:
Fixes T9599. When APC/APCu are not available, we fall back to a disk-based cache.
We try to share this cache across webserver processes like APC/APCu would be shared in order to improve performance, but are just kind of guessing how to coordinate it. From T9599, it sounds like we don't always get this right in every configuration.
Since this is complicated and error prone, just stop trying to do this. This cache has bad performance anyway (no production install should be using it), and we have much better APC/APCu setup instructions now than we did when I wrote this. Just using the PID is simpler and more correct.
Test Plan:
- Artificially disabled APC.
- Reloaded the page, saw all the setup stuff run.
- Reloaded the page, saw no setup stuff run (i.e., cache was hit).
- Restarted the webserver.
- Reloaded the page, saw all the setup stuff run.
- Reloaded again, got a cache hit.
I don't really know how to reproduce the exact problem with the parent PID not working, but from T9599 it sounds like this fixed the issue and from my test plan we still appear to get correct behavior in the standard/common case.

Summary: Reachable via the cache config page, restricted to admins only. This makes it convenient to hotfix phabricator without requiring a restart.
Test Plan:
- Local dev machine doesn't have apc, so I get the not installed message.
- Faked the name and isEnabled parameters, verified dialog shows up as expected.
- Didn't test clear code

Summary:
Ref T7811. Fixes two minor issues I observed in the cluster:
- Sometimes APC doesn't give us key names. Not sure exactly what's up here, but we can do a better job with this.
- The `%` in `25%` actually needs more escaping, since it's interpreted by both `pht()` (immediately) and `console_format()` (later).
Test Plan:
- First one is just from an error log, not sure how to repro offhand.
- Ran `bin/phd help start` for the second one.

Summary:
Ref T5501. Currently, we emit some bad warnings about, e.g., "apc.stat" on PHP 5.5+ systems with OPcache, where the warnings are not relevant.
Generate and raise warnings out of the CacheSpec pipeline so we only run relevant code.

In particular, this will make it much easier to lift these issues into setup warnings eventually.
