[pve-devel] [RFC v2 common 1/2] REST environment: add static log_warn function

[Fabian Ebner]

which avoids the need for the caller to check whether the environment
was initialized or not.

Changes from v1:
    * The static function now calls the class method, rather than the
      other way around. If the current environment is a derived class
      providing its own implementation of warn(), the static function
      will call that one.
