function _variable_realm_invoke_all in Variable 7.2

Invoke variable realm hook on all currently loaded modules.

Variable realm usually starts from bootstrap, on hook_boot() and from here it is not safe to user regular hook invokation so we use our own function, similar to bootstrap_invoke_all() but returning the values (with deep merge).

@pram $hook Hook to invoke in all loaded modules

Parameters

$arg1, $arg2...: A variable number of arguments.
