Summary:
Per the documentation[1], any intermediate chain is to be
appended to the "cert" parameter. The "ca" parameter controls the
root CA used to authenticate the client certificate, if one is
provided, and is not used for intermediate certificate chains -- nor
has it ever been. It is not clear how this could have worked in the
past[2].

Summary:
Ref T6915. This allows multiple notification servers to talk to each other:
- Every server has a list of every other server, including itself.
- Every server generates a unique fingerprint at startup, like "XjeHuPKPBKHUmXkB".
- Every time a server gets a message, it marks it with its personal fingerprint, then sends it to every other server.
- Servers do not retransmit messages that they've already seen (already marked with their fingerprint).
- Servers learn other servers' fingerprints after they send them a message, and stop sending them messages they've already seen.
This is pretty crude, and the first message to a cluster will transmit N^2 times, but N is going to be like 3 or 4 in even the most extreme cases for a very long time.
The fingerprinting stops cycles, and stops servers from sending themselves copies of messages.
We don't need to do anything more sophisticated than this because it's fine if some notifications get lost when a server dies. Clients will reconnect after a short period of time and life will continue.
Test Plan:
- Wrote two server configs.
- Started two servers.
- Told Phabricator about all four services.
- Loaded Chrome and Safari.
- Saw them connect to different servers.
- Sent messages in one, got notifications in the other (magic!).
- Saw the fingerprinting stuff work on the console, no infinite retransmission of messages, etc.
(This pretty much just worked when I ran it the first time so I probably missed something?)

Fixes T10783 (what little of it remains). Ref T10697.
Aphlict currently uses request paths for two different things:
- multi-tenant instancing in the Phacility cluster (each instance gets its own namespace within an Aphlict server);
- some users configure nginx and apache to do proxying or SSL termination based on the path.
Currently, these can collide.
Put a "~" before the instance name to make it unambiguous. At some point we can possibly just use a GET parameter, but I think there was some reason I didn't do that originally and this sequence of changes is disruptive enough already.
Test Plan: Saw local Aphlict unambiguously recognize "local.phacility.com" as instance "local", with a "~"-style URI.

Summary:
Ref T10697. Currently, `aphlict` takes a ton of command line flags to configure exactly one admin server and exactly one client server.
I want to replace this with a config file. Additionally, I plan to support:
- arbitrary numbers of listening client ports;
- arbitrary numbers of listening admin ports;
- SSL on any port.
For now, just transform the arguments to look like they're a config file. In the future, I'll load from a config file instead.
This greater generality will allow you to do stuff like run separate HTTP and HTTPS admin ports if you really want. I don't think there's a ton of use for this, but it tends to make the code cleaner anyway and there may be some weird cross-datacneter cases for it. Certainly, we undershot with the initial design and lots of users want to terminate SSL in nginx and run only HTTP on this server.
(Some sort-of-plausible use cases are running separate HTTP and HTTPS client servers, if your Phabricator install supports both, or running multiple HTTPS servers with different certificates if you have a bizarre VPN.)

Summary:
Fixes T7130. Fixes T7041. Fixes T7012.
Major change here is partitioning clients. In the Phacility cluster, being able to get a huge pile of instances on a single server -- without needing to run a process per instance -- is desirable.
To accomplish this, just bucket clients by the path they connect with. This will let us set client URIs to `/instancename/` and then route connections to a small set of servers. This degrades cleanly in the common case and has no effect on installs which don't do instancing.
Also fix two unrelated issues:
- Fix the timeouts, which were incorrectly initializing in `open()` (which is called during reconnect, causing them to reset every time). Instead, initialize in the constructor. Cap timeout at 5 minutes.
- Probably fix subscriptions, which were using a property with an object definition. Since this is by-ref, all concrete instances of the object share the same property, so all users would be subscribed to everything. Probably.
Test Plan:
- Hit notification status page, saw version bump and instance/path name.
- Saw instance/path name in client and server logs.
- Stopped server, saw reconnects after 2, 4, 16, ... seconds.
- Sent test notification; received test notification.
- Didn't explicitly test the subscription thing but it should be obvious by looking at `/notification/status/` shortly after a push.

- Writing or deleting properties which have there writeable or configurable attributes set to false will now throw an error instead of failing silently.
- Adding a property to an object whose extensible attribute is false will also throw an error now.
- A functions arguments are not writeable so attempting to change them will now throw an error `arguments = [...]`.
- `with(){}` statements are gone.
- Use of `eval` is effectively banned.
- `eval` and `arguments` are not allowed as variable or function identifiers in any scope.

Summary: Currently, the `AphlictClient` will only send its subscriptions to the `AphlictMaster` once. If the original `AphlictMaster` is closed and a new master is created, then client subscriptions will be lost.
Test Plan: Opened two separate tabs. Closed the "master" tab and noticed that the subscriptions were re-sent to the server.
