Transactions - change show all key from "~" to "@"

Summary: (some) international keyboard layouts can not type "~" in a way as to trigger this so use "@" instead. Save the suggested "+" as that seems like it would be useful for some future "adding stuff" keyboard workflow. Pretty stoked to get this squared away as I am quite confident our unreleased product will now be a huge smashing success. Ref T6683.

Test Plan: made sure my choice was okay via https://en.wikipedia.org/wiki/Dead_key#Dead_keys_on_various_keyboard_layouts; used the "@" key to show all transactions

Phriction - validateTransactions that need parent ancestry to complete successfully

Summary:
Fixes T6651, T6682. Since policy is defined by ancestry, you can't make things outside the core tree.

An alternative fix would be to automagically stub everything in these cases. This has potential negative policy implications - consider making a public document with several levels of depth that automagically stubs out its ancestry as public - and additionally the PhabricatorApplicationTransactionEditor framework would make this very tricky code (i.e. you are expected to validateTransactions in said hook *and* return an error if things aren't valid and not do some automagic stubbing, etc.)

Test Plan: tried to move a doc from location/that/exists to locationz/thatz/dontz/existz/ and got an error message with links to each missing doc. tried to create a doc at locatonz/thatz/dontz/existsz/ and got an error message with links to each missing doc.

Home - limit "status" queries to 100 and show 99+ if we hit that

Summary: Fixes T6595. This diff has two issues as is... 1) the differential data fetching is pretty cheesey, but it looks like we can't just issue three separate databases to get the right data? 2) the translations break, since I am turning this into a string (and not an int) so the whole pluralization bit fails. I think 1 is okay as is and 2 needs to be fixed though I am not sure how to best do that...

Test Plan: loaded home page and it looked nice...!

Allow repositories to be bound to an AlmanacService

Summary:
Ref T2783. This is primarily exploratory and just figuring out what we're blocked on:

  - Allow a Repository to be bound to a Service. The Service may eventually define multiple read/write nodes, etc.
    - There's no UI to do this binding yet, you have to touch the database manually.
  - If a repository is bound to a Service, effect Conduit calls via calls to the remote service instead of executing them in-process.
    - These don't actually work yet since there's no authentication (see T5955).

Test Plan:
  - Made a nice Service with a nice Binding to a nice Interface on a nice Device.
  - Force-associated a repository with the service using a raw MySQL query.
  - Saw Phabricator try to make a remote call to the service (on localhost) and fail because of missing auth stuff.
  - Also ran `almanac.queryservices`.

Prevent Phame blogs from using invalid skins

Summary: Via HackerOne. An attacker with access to both Phame and the filesystem could potentially load a skin that lives outside of the configured skin directories, because we had insufficient checks on the actual skin at load time.

Test Plan: Attempted to build a blog with an invalid skin; got an exception instead of a mis-load of a sketchy skin.

Lock `phabricator.show-prototypes`

Summary:
Two goals:

  - If an attacker compromises an administrator account (without compromising the host itself), they can currently take advantage of vulnerabilities in prototype applications by enabling the applications, then exploiting the vulnerability. Locking this option requires CLI access to enable prototypes, so installs which do not have prototypes enabled have no exposure to security issues in prototype applications.
  - Making this very slightly harder to enable is probably a good thing, given the state of the world and support.

Test Plan: Verified that web UI shows the value is locked and instructs the user to update via the CLI.

Add Conduit Tokens to make authentication in Conduit somewhat more sane

Summary:
Ref T5955. Summary of intended changes:

**Improve Granularity of Authorization**: Currently, users have one Conduit Certificate. This isn't very flexible, and means that you can't ever generate an API token with limited permissions or IP block controls (see T6706). This moves toward a world where you can generate multiple tokens, revoke them individually, and assign disparate privileges to them.

**Standardize Token Management**: This moves Conduit to work the same way that sessions, OAuth authorizations, and temporary tokens already work, instead of being this crazy bizarre mess.

**Make Authentication Faster**: Authentication currently requires a handshake (conduit.connect) to establish a session, like the web UI. This is unnecessary from a security point of view and puts an extra round trip in front of all Conduit activity. Essentially no other API anywhere works like this.

**Make Authentication Simpler**: The handshake is complex, and involves deriving hashes. The session is also complex, and creates issues like T4377. Handshake and session management require different inputs.

**Make Token Management Simpler**: The certificate is this huge long thing right now, which is not necessary from a security perspective. There are separate Arcanist handshake tokens, but they have a different set of issues. We can move forward to a token management world where neither of these problems exist.

**Lower Protocol Barrier**: The simplest possible API client is very complex right now. It should be `curl`. Simplifying authentication is a necessary step toward this.

**Unblock T2783**: T2783 is blocked on nodes in the cluster making authenticated API calls to other nodes. This provides a simpler way forward than the handshake mess (or enormous-hack-mess) which would currently be required.

Test Plan:
  - Generated tokens.
  - Generated tokens for a bot account.
  - Terminated tokens (and for a bot account).
  - Terminated all tokens (and for a bot account).
  - Ran GC and saw it reap all the expired tokens.

NOTE: These tokens can not actually be used to authenticate yet!

Accept Conduit tokens as an authentication mechanism

Summary:
  - Ref T5955. Accept the tokens introduced in D10985 as an authentication token.
  - Ref T3628. Permit simple `curl`-compatible decoding of parameters.

Test Plan:
  - Ran some sensible `curl` API commands:

```

```

  - Ran older-style commands like `arc list` against the local install.
  - Ran commands via web console.
  - Added and ran a unit test to make sure nothing is using forbidden parameter names.
  - Terminated a token and verified it no longer works.

Add conduit.getcapabilities and a modern CLI handshake workflow

Summary:
Ref T5955.

  - Add `conduit.getcapabilities` to help arc (and other clients) determine formats, protocols, etc., the server supports.
  - Fixes T3117. Add a more modern version of the handshake workflow that allows all generated tokens to remain valid for an hour.
  - Generally, add a CLI token type. This token type expires after an hour when generated, then becomes permanent if used.

Test Plan:
  - See D10988.
  - Ran `conduit.getcapabilities` and inspected output.

Generate and use "cluster" Conduit API tokens

Summary:
Ref T5955. Ref T2783.

  - Removes the "temporary" type. I was going to use this for T3628 but it started taking more time than I wanted to spend on it.
  - Add a "cluster" type, which is an internal-only token type used within a cluster. This token value is never shown to the user.
  - Automatically generate, use, and cycle cluster tokens.

Test Plan:
  - Diffusion (mostly) works with a repository configured to use a remote service.
  - Saw cluster tokens generate; terminated a cluster token and saw it regenerate.
  - Viewed cluster token in settings panel and saw nice explanatory text instead, as expected (we might just hide these eventually).
