* strip out the href and xlink:href attributes from use element that
are _not_ anchors in svgs which can be used for XSS
* adding the content-disposition: attachment ensures that
uploaded SVGs cannot be opened and executed using the XSS exploit.
svgs embedded using an img tag do not suffer from the same exploit
* FIX: Improve category hashtag lookup
This commit improves support for sub-sub-categories and does not include
the ID of the category in the slug, which fixes the composer preview.
* FIX: Sub-sub-categories can be mentioned using only two levels
* FIX: Remove support for three-level hashtags
* DEV: Simplify code
The previous fix (f43c0a5d857d34) wasn't working for images that were already uploaded.
The "metadata" (eg. 'for_*' and 'secure' attributes) were not added to existing uploads.
Also used 'Upload.get_from_url' is the admin/site_setting controller to properly retrieve
an upload from its URL.
Fixed the Upload::URL_REGEX to use the \h (hexadecimal) for the SHA

* Change S3Helper::DOWNLOAD_URL_EXPIRES_AFTER_SECONDS to 5 minutes, which controls presigned URL expiry and secure-media route cache time.
* This is done because of the composer preview refreshing while typing causes a lot of requests sent to our server because of the short URL expiry. If this ends up being not enough we can always increase the time or explore other avenues (e.g. GitHub has a 7 day validity for secure URLs)
In 91c89df6, I fixed the onebox to support local topics with a slug-less URL.
This commit fixes all the other spots (search, topic links and user badges) where we look up for a local topic.

Google no longer supports the use of robots.txt to block indexing.
See https://support.google.com/webmasters/answer/6062608 and
https://support.google.com/webmasters/answer/93710
Previous commits have added the `noindex` header to appropriate pages,
now we need to remove the paths from robots.txt so the pages can be
crawled.

* FEATURE: Don't display muted/ignored users under "who liked"
Previously, if you clicked on the heart icon below a post
it would show you the avatar for a user even if you ignored or muted
them.
This commit will instead display a (?) icon. The count of likes will
remain correct, but you needn't be reminded of the person you
preferred not to see.
* Use a circle instead of (?) for unknown user
There are two problems I'm trying to tackle here.
1. The site json is cached for anonymous users so readonly mode can be
cached for up to 30 minutes which makes it confusing.
2. We've already checked for readonly mode in the controller so having
to check for readonly mode again in `SiteSerializer` is adding an extra
Redis query on every request.
Adds new hidden site settings for rate limits:
30 for logged in users, 15 for anon
Adds an anon cache for searching, caches results of searches for 1 minute
Discourse needs a bunch of data preloaded before it can start up.
Normally we throw blobs of this into the HTML document that is requested
but in some cases that's awkward to retrieve.
For example with Ember CLI you have a separate javascript application
that needs to make its own HTML.
This API endpoint returns a JSON object with all the data Discourse needs to
bootstrap and start up.
In some restricted setups all JS payloads need tight control.
This setting bans admins from making changes to JS on the site and
requires all themes be whitelisted to be used.
There are edge cases we still need to work through in this mode
hence this is still not supported in production and experimental.
Use an example like this to enable:
`DISCOURSE_WHITELISTED_THEME_REPOS="https://repo.com/repo.git,https://repo.com/repo2.git"`
By default this feature is not enabled and no changes are made.
One exception is that default theme id was missing a security check
this was added for correctness.
Fixes a regression in
e8fb9d406667c758cba0f7b1cc779e1ceb352c4c
which caused a bug where you couldn't send a message to a group that
contained an Uppercase letter. Added a test case for this.

* FIX: add X-Robots-Tag header for check_xhr-covered GET actions, too
see https://meta.discourse.org/t/missing-x-robots-tag/152593/3 for context
* test: a spec making sure X-Robots-Tag header is present when needed
/groups path responds to anonymous requests and doesn't skip `check_xhr` method, so we can use it here.
