Stefan Kalkowski 5447c406e5 thread: rearrange thread context management ... Use a bit allocator for the allocation management of thread contexts, instead of holding allocation information within the Thread_base objects, which lead to race conditions in the past. Moreover, extend the Thread_base class interface with the ability to to add additional stacks to a thread, and associate the context they're located in with the corresponding Thread_base object. Additional stacks can be used to do user-level scheduling with stack switching, without breaking Genode's API. Fixes #1024 Fixes #1036		2014-01-27 18:54:09 +01:00
