[PATCH 00/21] Support statically allocated threads

[Sebastian Huber]

This change set makes it possible to statically allocate threads.  This means
the thread control block is provided by a statically allocated thread
information and the thread stack is provided by the user.  Currently, no API
function exists for this.  Adding this API is a follow up change set.  Only the
internal threads use statically allocated thread stacks in this change set.

Sebastian Huber (21):
  score: Remove superfluous FP types/defines
  score: Simplify thread stack allocation
  score: Simplify thread stack free
  score: Remove _Stack_Ensure_minimum() call
  score: Simplify FP context allocation
  score: Simplify TLS area allocation
  score: Split stack allocator configuration
  score: Add Thread_Configuration
  score: Add _Stack_Extend_size()
  score: Move thread stack allocation
  score: Statically allocate idle/MPCI stacks
  score: Add _Objects_Free_objects_block()
  score: Split up objects allocation
  score: Split up objects free
  score: Inline _Objects_Namespace_remove_u32()
  score: _Objects_Extend_information()
  score: Add _Freechain_Is_empty()
  score: Add _Freechain_Pop()
  score: Add _Freechain_Extend()
  score: Add _Objects_Activate_unlimited()
  score: Simplify _Thread_Initialize()
