Psql

[pkuwwt]

Description
Add sql support in addition to bolt, including sqlite3, postgres, mysql.

Most code are in storage/sql, except a few lines in cmd/root.go and cmd/utils.go.

Usage

filebrowser -d sqlite3://test.db
filebrowser -d 'postgres://user:password@192.168.1.100:5432/postgres?sslmode=disable'

Reason
Bolt is a relative non-mainstream choice for storage. When someone use filebrowser as a component of a project, he/she will need a centralized storage server, e.g. postgres, mysql, other than bolt.

Can any effort be put into merging this? Filebrowser CLI cannot be used inside container or while it's running in general, because of the exclusive database lock. This is seriously inconvenient. I am forced at this point to either kill filebrowser every time I want to run a CLI command, or build this PR for use in production. This also affects automation and makes it difficult to programmatically add users (for example) based on other input. I would use the API but it is not documented and seems fiddly to use, #2551.

I built this and merged with master. Works with Postgres, but I've found some issues.

1. The github.com/mattn/go-sqlite3 library isn't being updated anymore, and the last release is from 2022. It didn't build successfully on my machine, and I had to update it to the latest Git commit v0.0.0-20240202170028-6ee3e6746e6b to build.
2. AuthMethod of type proxy does not seem to work. It either isn't grabbing the header from the auther row, or is not being properly substituted in the SQL statement. I am investigating.
   The statement being run:

   SELECT id,username,password,scope,locale,lockpassword,viewmode,perm,commands,sorting,rules,hidedotfiles,dateformat,singleclick FROM "fb_users" WHERE username=''

   As a consequence of this, I see the login page since it is shown when the user either doesn't exist or isn't authed properly, as noted in many other issues.
   Actually, this seems to be an upstream bug. Proxy auth doesn't work #2995
3. config set attempts to insert already existing rows, like Root and Socket. I had to delete all the offending rows to allow it to re-insert them in order to use the command and add new values.
