This endpoint returns the internal readiness state used by
the realtime code to indicate whether HedgeDoc is performing
properly. As it only returns the state of a variable, it is
less resource hungry compared to a call to /status for
checking the health of HedgeDoc.
By prepending the route with an underscore, it should not be conflicting with already created pads in FreeURL mode.

The markdown for the publish-view is generated
using the `Note.extractMeta` method.
It uses meta-marked to separate the metadata from markdown.
Only the raw markdown is then sent to the client,
so it cannot respect the `breaks` option.
This adds an evil hack to send the `breaks` option with the markdown
if it is contained in the metadata block.

Since https://github.com/vesse/node-ldapauth-fork/commit
/741a648df98d789856b3301d65103b74872fdeea, ldapauth-fork calls `push` on
the attributes array.
Since we deep-freeze our config object in https://github
.com/hedgedoc/hedgedoc/blob/master/lib/config/index.js#L200, this
causes a crash.
This commit fixes the crash by creating a mutable clone of the LDAP
config and passing that to the LDAP strategy.

This patch adds an own filename function for `formidable`, which will
make sure to generate a random file name, using UUIDv4. This should
resolve GHSA-q6vv-2q26-j7rx.
This change is required due to a change in behaviour from version 1 to
version 2 of formidable. Formidable version 2 will generate predictable
filenames by default, which results in potential access to images, that
were uploaded while formidable v2 was used in Hedgedoc. This affects the
versions `1.9.1` and `1.9.2`.
Files generated previous to this commit will look like this:
```
<random string generated on app start><counter>.<file-extension>
38e56506ec2dcab52e9282c00.jpg
38e56506ec2dcab52e9282c01.jpg
38e56506ec2dcab52e9282c02.jpg
```
After this patch it'll look like this:
```
<uuid v4>.<file-extension>
a67f36b8-9afb-43c2-9ef2-a567a77d8628.jpg
56b3d5d0-c586-4679-9ae6-d2044843c2cd.jpg
2af727ac-a2d4-4aad-acb5-73596c2a7eb6.jpg
```
This patch was implemented using `uuid` since we already utilise this
package elsewhere in the project as well as using a secure function to
generate random strings. UUIDv4 is ideal for that. In order to be
consumable by formidable, it was wrapped in a function that makes sure
to keep the file extension.
This vulnerability was reported by Matias from [NCSC-FI](https://www.kyberturvallisuuskeskus.fi/).

We use the attribute `emails` (plural) for email addresses with other auth providers like LDAP or SAML. In case of OAuth2 we used the attribute `email` (singular) which resulted in problems.
Furthermore the OAuth2 strategy fell into the default fallback of the provider switch statement. This statement did not check email addresses but did generate the letter-avatar instantly.

This patch fixes the swollowing of the actual error message that appears
when a file fails to move, after being uploaded to Hedgedoc on an
instance that is using the upload-method `filesystem` active.
This became apparent when the error messages provided by some users,
where less than helpful.
As a solution the error message of the copy command was added to the
error that is output to the console.

When FreeURL mode is enabled and you called the /download route, the note was created and the user redirected to the blank note.
This is caused because the findNote method automatically creates a note when no existing one is found.
This commit adds a new parameter to the findNote method which allows to disable this behaviour. In that case a HTTP 404 error will be returned.

This patch fixes the issue of unauthenticated users, being able to
upload files, even when anonymous edits are disabled.
It's implemented by blocking uploads when either `allowAnonymous` is set
to `false` for all unauthenticated users, unless `allowAnonymousEdits`
is set to true, to make sure anonymous editors still experience the full
feature set.

This patch fixes a security issue with all existing CodiMD and HedgeDoc
installation which allows arbitary file uploads to instances that expose
the `/uploadimage` API endpoint. With the patch it implies the same
restrictions on the MIME-types as the frontend does. Means only images
are allowed unless configured differently.
This issue was reported by Thomas Lambertz.
To verify if you are vulnerable or not, create two files `test.html` and
`test.png` and try to upload them to your hedgedoc installation.
```
curl -X POST -F "image=@$(pwd)/test.html" http://localhost:3000/uploadimage
curl -X POST -F "image=@$(pwd)/test.png" http://localhost:3000/uploadimage
```
Note: Not all backends are affected. Imgur and lutim should prevent this
by their own upload API. But S3, minio, filesystem and azure, will be at
risk.
Addition Note: When using filesystem instead of an external uploads
providers, there is a higher risk of code injections as the default CSP
do not block JS from the main domain.
