Summary:
Depends on D20140. Ref T13250. Currently, the top-level exception handler doesn't dump stacks because we might not be in debug mode, and we might double-extra-super fatal if we call `PhabricatorEnv:...` to try to figure out if we're in debug mode or not.
We can get around this by setting a flag on the Sink once we're able to confirm that we're in debug mode. Then it's okay for the top-level error handler to show traces.
There's still some small possibility that showing a trace could make us double-super-fatal since we have to call a little more code, but AphrontStackTraceView is pretty conservative about what it does and 99% of the time this is a huge improvement.

Summary:
Ref T12907. At least part of the problem is that we can hit PHP's `max_execution_time` limit on the file download pathway.
We don't currently set this to anything in the application itself, but PHP often sets it to 30s by default (and we have it set to 30s in production).
When writing responses, remove this limit. This limit is mostly a protection against accidental loops/recurison/etc., not a process slot protection. It doesn't really protect process slots anyway, since it doesn't start counting until the request starts executing, so you can (by default) //send// the request as slowly as you want without hitting this limit.
By releasing the limit this late, hopefully all the loops and recursion issues have already been caught and we're left with mostly smooth sailing.
We already remove this limit when sending `git clone` responses in `DiffusionServeController` and nothing has blown up. This affects `git clone http://` and similar.
(I may have had this turned off locally and/or just be too impatient to wait 30s, which is why I haven't caught this previously.)
Test Plan:
- Poked around and downloaded some files.
- Will `curl ...` in production and see if that goes better.

Summary:
Fixes T12013. Send either "Content-Length" or enable output compression, but not both.
Prefer compression for static resources (CSS, JS, etc).
Test Plan: Ran `curl -v ...`, no longer saw responses with both compression and `Content-Length`.

Summary: Fixes T7620. I don't fully understand exactly what's going on here, but we don't actually need to call `flush()`.
Test Plan:
- Put timing code around the `echo`.
- Made a fake page that emitted a lot of data.
- Saw the `echo` block proportionate to data size under `curl --limit-rate ...`.
- See T7620.
- Downloaded a large file, got a reasonable progress bar and no obvious memory use issues.

Summary:
Ref T7149. This still buffers the whole file, but is reaaaaal close to not doing that.
Allow Responses to be streamed, and rewrite the range stuff in the FileResponse so it does not rely on having the entire content available.
Test Plan:
- Artificially slowed down downloads, suspended/resumed them (works in chrome, not so much in Safari/Firefox?)
- Played sounds in Safari/Chrome.
- Viewed a bunch of pages and files in every browser.

Summary:
Mostly ripped from D7391, with some changes:
- Serve repositories at `/diffusion/X/`, with no special `/git/` or `/serve/` URI component.
- This requires a little bit of magic, but I got the magic working for Git, Mercurial and SVN, and it seems reasonable.
- I think having one URI for everything will make it easier for users to understand.
- One downside is that git will clone into `X` by default, but I think that's not a big deal, and we can work around that in the future easily enough.
- Accept HTTP requests for Git, SVN and Mercurial repositories.
- Auth logic is a little different in order to be more consistent with how other things work.
- Instead of AphrontBasicAuthResponse, added "VCSResponse". Mercurial can print strings we send it on the CLI if we're careful, so support that. I did a fair amount of digging and didn't have any luck with git or svn.
- Commands we don't know about are assumed to require "Push" capability by default.
No actual VCS data going over the wire yet.
Test Plan:
Ran a bunch of stuff like this:
$ hg clone http://local.aphront.com:8080/diffusion/P/
abort: HTTP Error 403: This repository is not available over HTTP.
...and got pretty reasonable-seeming errors in all cases. All this can do is produce errors for now.

Summary:
In the past, we did some additional magic on `$response_string` (adding profiling headers? Or DarkConsole?), so we could not share the pathway with HTTPSink. We no longer do this; share the pathways.
Also remove error handler initialization (duplicated in PhabricatorEnv), and move $sink initialization earlier. My general goal here is to allow PhabricatorSetup to emit a normal Response object and share as much code as possible with normal pages.
Test Plan: Loaded page.

Summary:
This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory).
We are removing the headers for these reasons:
- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.
This change is approved by Alma Chao (Lead Open Source and IP Counsel at Facebook).
Test Plan: Verified that the license survived only in LICENSE file and that it didn't modify externals.

Some browsers will still sniff content types even with "Content-Type" and
"X-Content-Type-Options: nosniff". Encode "<" and ">" to prevent them from
sniffing the content as HTML.

This addresses a few things:
- Provide a software HTTP response spliting guard as an extra layer of
security, see http://news.php.net/php.internals/57655 and who knows what HPHP/i
does.
- Cleans up webroot/index.php a little bit, I want to get that file under
control eventually.
- Eventually I want to collect bytes in/out metrics and this allows us to do
that easily.
- We may eventually want to write to a socket or do something else like that,
ala Litespawn.
Test Plan:
- Ran unit tests.
- Browsed around, checked headers and HTTP status codes.
