Consistent definition of priority levels
In the specs and the documentation of the spawn_opt family of functions
there is the following definition of priority levels:
Level = low | normal | high
However, the process_flag/1 function in that module reads:
process_flag(Flag :: priority, Level) -> OldLevel
Types:
Level = OldLevel = priority_level()
priority_level() = low | normal | high | max
This is clearly inconsistent. Change specs to use the process_level()
type declaration instead of re-defining it in various places.
