Rspamd currently sends reply in JSON format. However, message pack seems to
be a better choice for a compatible client. It is faster and does not need
escaping or even UTF8 validation. This is a surface for further updates.

Further optimization to the hot path of lua userdata checks

We check userdata very frequently, so the idea here is the following:

- Store the address of classname (converted to int) in the metatable at index 1
- When we need to check some udata, we can just compare the static address with
  the integer stored in metatable
- This avoid quite an expensive `lua_rawequal` call for two tables as we know that
  our classes are quite static

[Minor] Add HAS_FILE_URL rule for messages containing a file:// URL

These are frequently abused for distributing malware via non-HTTP
protocols, such as public Samba servers. file:// URLs may also be abused
for including files from the victims' machine in a message. Either way,
a legitimate usecase is unlikely.
