Instead of using sequelize-cli and ensure migrations by shellscript,
this patch automates database migrations properly to the umzug library.
The sequelize CLI becomes a dev dependencies as it's still useful for
generating migrations.
This should eliminate the need for crude generating of database config
files and alike. Instead we utilize the pre-configured sequelize
connection that CodiMD will use anyway.

This is a forward-port of d6ce60c.
The old pg version doesn't work with node version 14 due to
an undocumented API change in the `readyState` in the socket API.
This patch updates the required dependency and this way resolves the
issue.

dmpWorker is run as a childProcess, which is a completely separate
nodejs instance. As such, the `logger` it obtains is a separate instance
than the one in the parent. The parent reads the config file to
determine the log level, but the childProcess does not. So the log level
used in dmpWorker is always `debug`, regardless of the configuration
options.
In addition to polluting the logs, this is potentially a privacy issue,
because `dmpWorker` logs the diffs of notes at the `debug` level, which
will then enter the system logs.
This commit fixes this by making `dmpWorker` send any messages back to
the parent, who is responsible for logging. This also avoids any
potential race conditions between the two loggers writing to the same
output.

Our frontend requests the `/me` pathname in order to determine whether
it's logged in or not. Due to the fact that the sameSite attribute of
the session cookie was set to `strict` in a previous commit, the session
token was no longer sent along with HTTP calls initiated by JS. This is
due to the RFCs definition of "safe" HTTP calls in RFC7231.
The bug triggers the UI to show up like an unauthenticated user, even
after a successful login. In order to debug it a look into the send
cookies to the `/me` turned out to be very enlightening.
The fix this patch implements is rather simple, it replaces the sameSite
attribute to `lax` which enables the cookies for those requests again.
Some older and mobile clients were unaffected by this due to the lack of
implementations of sameSite policies.

We enabled the `secure` flag for various cookies in previous commits.
This caused setups behind reverse proxies to drop cookies as the nodejs
instance wasn't aware of the fact that it was able to hand out secure
commits using an insecure connection (between the codimd instance and
the reverse proxy).
This patch makes express, the webserver framework we use, aware of
proxies and this way re-enabled the handing out of cookies. Not only the
cookie monster will enjoy, but also functionality like authentication
and real-time editing will return as intended.

While HSTS should take care of most of this, setting cookies to be
secure, and only applied on same site helps to improve situations where
for whatever reason, downgrade attacks are still a thing.
This patch adds the `sameSite` and `secure` to the session cookie and
this way prevent all accidents where a browser may doesn't support HSTS
or HSTS is intentionally dropped.

Modern browsers do not support (or will stop supporting) sameSite: none (or no sameSite attribute) without the Secure flag. As we don't want everyone to be able to make requests with our cookies anyway, this commit sets sameSite to strict. See https://developer.mozilla.org/de/docs/Web/HTTP/Headers/Set-Cookie/SameSite

Synk reported an Remote Code Execution vulnerability for the
passport-ldapauth dependency `bunyan`. This RCE is due to wrong command
sanitizing but doesn't only affects the executable the libary provides.
It has no impact on CodiMD.
This patch just updates passport-ldapauth since it's long overdue anyway
and to silence annoying security scanners that pretend this is rather
critical for us.

Previously, upon receiving a termination signal, the process tries to
flush all changes to the database, retrying every 0.1s until it
succeeds. However, if the database is not set up properly, this always
fails, and spams the terminal/logging with the error message 10 times a
second.
If the user sends another termination signal, the handleTermSignal
function is called once again, and we get twice the number of error
messages.
This commit changes the behaviour in various ways.
(1) It lowers the retry rate to 0.5s, and aborts after 30 seconds.
(2) If the write to the database errored, the error message explains
that this is due to us flushing the final changes.
(3) We replace realtime.maintenance with realtime.state, which is an
Enum with three possible states --- Starting, Running, and Stopping.
If a termination signal is received in the starting state, the
process simply aborts because there is nothing to clean up. This is
the case when the database is misconfigured, since the application
starts up only after connecting to the databse. If it is in the
Stopping state, the handleTermSignal function returns because
another instance of handleTermSignal is already running.

OAuth2 allows the user to only consent to a subset of the scopes
requested. Previously, the Generic Oauth2 implementation assumes that
the `username`, `email` and `displayName` attributes are supplied, and
may crash if they are not defined.
This commit allows for `email` and `displayName` to not be defined,
either through the user refusing consent or the OAuth2 configuration
not asking for them in the first place (by not setting
`userProfile*Attr`).
If `email` is not provided, the `emails` property is simply left empty.
If `displayName` is not provided, it is left undefined, and CodiMD uses
the `username` whenever the `displayName` is expected.
This does not deal with the case where `username` is not provided. Since
usernames are not unique in CodiMD, it is possible to deal with this by
setting a dummy username. This can be added in a future commit if
desired.

This allows configuring the group and mode of the unix socket after it
has been created to allow reverse proxies to access it. Fixes#317.
I decided to call `chown` and `chgrp` directly to change the owner and
group (the former will almost definitely not be called; only root can
chown a file to another user, and you are not running codimd as root. It
is included for consistency).
The nodejs chown/chgrp functions only accepts uid and gid, not the names
of the user or group. The standard way to convert a group name into a gid
is the `uid-number` package. The way this package works is that
1. It spawns a new nodejs process
2. The new nodejs process calls nodejs' setgid function, which *does*
accept both the group name and gid
3. It then calls getuid to retrieve the uid of the process, and returns
it to the parent process via stdout.
While this *works*, it is hacky, and if we are spawning a process
anyway, might as well call `chgrp` directly.
This does not update the documentation because we are merging into
release/2.0.x but master reworks the configuration section of the
documentation, so there will be a conflict when we merge anyway.

The code intends to check if the note is anonymous by checking if it has
an owner. If it is anonymous, the default permission must be `freely`.
However, at this point in the code, `owner` is never populated; only
`ownerId` is. The property `owner` is automatically filled in *after*
the Note is created, but this call happens before that.
Thus, the default note permission is always `freely`, regardless of the
`defaultPermission` setting. By checking `ownerId` instead of `owner`,
the anonymity and hence default permission is correctly determined,
This is especially an issue when `allowAnonymous` is `false`, since this
would allow the user to create a note with `freely` permission when it
should not be allowed.

It should be possible to run a backend build without the need to start
the application and without the need to fiddle around with PATH or
fiddling with `node_modules`. Therefore this patch splits the build
command into `build-frontend` and `build-backend`, which will allow
those builds to be done independent and have a separate command `build`
which will provide the combination of both of them.
