Summary:
Ref T11469. This isn't directly related, but has been on my radar for a while: building SSH keyfiles (particular for installs with a lot of keys, like ours) can be fairly slow.
At least one cluster instance is making multiple clone requests per second. While that should probably be rate limited separately, caching this should mitigate the impact of these requests.
This is pretty straightforward to cache since it's exactly the same every time, and only changes when users modify SSH keys (which is rare).
Test Plan:
- Ran `bin/auth-ssh`, saw authfile generate.
- Ran it again, saw it read from cache.
- Changed an SSH key.
- Ran it again, saw it regenerate.

This updates the eye logo and removes the formal wordmark "Phabricator" as an image. Instead we'll use the new updated eye logo and plain text for "Phabricator", both of which are more friendly and less industrial.
Installs that already use the `header-logo` customization setting will need to rebuild their logo to 80px x 80px. They will then also get to use plain text to whitebox their install as they see fit.
Test Plan:
Tested new logo at desktop, tablet, and mobile sizes. Set a random instance name, saw new wordmark. Created a really long wordmark of MMMMMMMMMMMM, saw text cut off so UI doesn't break. May need some additional tweaking, but I think we covered the most edge cases here.

Ref T10547. This has been around for a while but I was never able to reproduce it. I caught a repro case in the cluster recently and I think this is the right fix.
We tell Subversion to run `ssh-connect` instead of `ssh` so we can provide options and credentials, by using `SVN_SSH` in the environment. Subversion will sometimes kill the SSH tunnel subprocess aggressively with SIGTERM -- as of writing, you can search for `SIGTERM` in `make_tunnel()` here:
http://svn.apache.org/repos/asf/subversion/trunk/subversion/libsvn_ra_svn/client.c
By default, when a PHP process gets SIGTERM it just exits immediately, without running destructors or shutdown functions. Since destructors/shutdown functions don't run, `TempFile` doesn't get a chance to remove the file.
I don't have a clear picture of //when// Subversion sends SIGTERM to the child process. I can't really get this to trigger locally via `svn`, although I was able to get it to trigger explicitly. So I'm only about 95% sure this fixes it, but it seems likely.
Test Plan:
Locally, I couldn't get this to reproduce "normally" even knowing the cause (maybe Subversion doesn't do the SIGTERM stuff on OSX?) but I was able to get it to reproduce reliabily by adding `posix_kill(getmypid(), SIGTERM);` to the body of the script.
With that added, running the script with `PHABRICATOR_CREDENTIAL=PHID-CDTL-...` in the environment reliably left straggler temporary files.
Adding `declare()` and a signal handler fixed this: the script now runs the `TempFile` destructor and longer leaves the stragglers around.

Summary:
Ref T10917. Currently, when you delete an SSH key, we really truly delete it forever.
This isn't very consistent with other applications, but we built this stuff a long time ago before we were as rigorous about retaining data and making it auditable.
In partiular, destroying data isn't good for auditing after security issues, since it means we can't show you logs of any changes an attacker might have made to your keys.
To prepare to improve this, stop destoying data. This will allow later changes to become transaction-oriented and show normal transaction logs.
The tricky part here is that we have a `UNIQUE KEY` on the public key part of the key.
Instead, I changed this to `UNIQUE (key, isActive)`, where `isActive` is a nullable boolean column. This works because MySQL does not enforce "unique" if part of the key is `NULL`.
So you can't have two rows with `("A", 1)`, but you can have as many rows as you want with `("A", null)`. This lets us keep the "each key may only be active for one user/object" rule without requiring us to delete any data.
Test Plan:
- Ran schema changes.
- Viewed public keys.
- Tried to add a duplicate key, got rejected (already associated with another object).
- Deleted SSH key.
- Verified that the key was no longer actually deleted from the database, just marked inactive (in future changes, I'll update the UI to be more clear about this).
- Uploaded a new copy of the same public key, worked fine (no duplicate key rejection).
- Tried to upload yet another copy, got rejected.
- Generated a new keypair.
- Tried to upload a duplicate to an Almanac device, got rejected.
- Generated a new pair for a device.

Ref T4292. When you run `git fetch` and connect to, say, `repo001.west.company.com`, we'll look at the current version of the repository in other nodes in the cluster.
If `repo002.east.company.com` has a newer version of the repository, we'll fetch that version first, then respond to your request.
To do this, we need to run `git fetch repo002.east.company.com ...` and have that connect to the other host and be able to fetch data.
This change allows us to run `PHABRICATOR_AS_DEVICE=1 git fetch ...` to use device credentials to do this fetch. (Device credentials are already supported and used, they just always connect as a user right now, but these fetches should be doable without having a user. We will have a valid user when you run `git fetch` yourself, but we won't have one if the daemons notice that a repository is out of date and want to update it, so the update code should not depend on having a user.)

Summary:
Ref T7034.
In a cluster environment, when a user connects with a VCS request over SSH (like `git pull`), the receiving server may need to proxy it to a server which can actually satisfy the request.
In order to proxy the request, we need to know which repository the user is interested in accessing.
Split the SSH workflow into two steps:
# First, identify the repository.
# Then, execute the operation.
In the future, this will allow us to put a possible "proxy the whole thing somewhere else" step in the middle, mirroring the behavior of Conduit.
This is trivially easy in `git` and `hg`. Both identify the repository on the commmand line.
This is fiendishly complex in `svn`, for the same reasons that hosting SVN was hard in the first place. Specifically:
- The client doesn't tell us what it's after.
- To get it to tell us, we have to send it a server capabilities string //first//.
- We can't just start an `svnserve` process and read the repository out after a little while, because we may need to proxy the request once we figure out the repository.
- We can't consume the client protocol frame that tells us what the client wants, because when we start the real server request it won't know what the client is after if it never receives that frame.
- On the other hand, we must consume the second copy of the server protocol frame that would be sent to the client, or they'll get two "HELLO" messages and not know what to do.
The approach here is straightforward, but the implementation is not trivial. Roughly:
- Start `svnserve`, read the "hello" frame from it.
- Kill `svnserve`.
- Send the "hello" to the client.
- Wait for the client to send us "I want repository X".
- Save the message it sent us in the "peekBuffer".
- Return "this is a request for repository X", so we can proxy it.
Then, to continue the request:
- Start the real `svnserve`.
- Read the "hello" frame from it and throw it away.
- Write the data in the "peekBuffer" to it, as though we'd just received it from the client.
- State of the world is normal again, so we can continue.
Also fixed some other issues:
- SVN could choke if `repository.default-local-path` contained extra slashes.
- PHP might emit some complaints when executing the commit hook; silence those.
Test Plan: Pushed and pulled repositories in SVN, Mercurial and Git.

Summary:
Fixes T7019. In a cluster environment, pushes currently fail because the commit hook can't identify the instance.
For web processes, the hostname identifies the instance -- but we don't have a hostname in the hook.
For CLI processes, the environment identifies the instance -- but we don't have an environment in the hook under SVN.
Promote the instance identifier into the upstream and pack/unpack it explicitly for hooks. This is probably not useful for anyone but us, but the amount of special-purpose code we're introducing is very small.
I poked at trying to do this in a more general way, but:
- We MUST know this BEFORE we run code, so the normal subclassing stuff is useless.
- I couldn't come up with any other parameter which might ever be useful to pass in.
Test Plan: Used `git push` to push code through proxied HTTP, got a clean push.
