This patch set replaces the CPU budget algorithm enumeration with a set of CPU
budget operations which implement a particular CPU budget algorithm. This
helps to hide the CPU budget algorithm implementation details from the general
thread handling. The CPU budget callouts are turned into CPU budget
operations. This slightly reduces the size of the thread control block.
All schedulers used the default scheduler tick implementation. The tick
scheduler operation is removed and the CPU budget operations are directly used
in _Watchdog_Tick() if the executing thread uses a CPU budget algorithm. This
is performance improvement for all threads which do not use a CPU budget
algorithm (default behaviour).

Use the new Priority_Group_order enum instead of a boolean to indicated if a
priority should be inserted as the first or last node into its priority group.
This makes the code more expressive. It is also a bit more efficient since a
branch in _Scheduler_Node_set_priority() is avoided and a simple bitwise or
operation can be used.

Move the CPU time budget to the thread configuration. This simplifies
_Thread_Initialize().

Add priority nodes which contribute to the overall thread priority.
The actual priority of a thread is now an aggregation of priority nodes.
The thread priority aggregation for the home scheduler instance of a
thread consists of at least one priority node, which is normally the
real priority of the thread. The locking protocols (e.g. priority
ceiling and priority inheritance), rate-monotonic period objects and the
POSIX sporadic server add, change and remove priority nodes.
A thread changes its priority now immediately, e.g. priority changes are
not deferred until the thread releases its last resource.
Replace the _Thread_Change_priority() function with
* _Thread_Priority_perform_actions(),
* _Thread_Priority_add(),
* _Thread_Priority_remove(),
* _Thread_Priority_change(), and
* _Thread_Priority_update().
Update #2412.

Instead of lowering the priority in case the initial budget is consumed
raise the priority for each new period. Restore the normal priority
once the initial budget is consumed. This makes it later easier to
combine the high priority phase with temporary priority boosts (e.g. via
priority ceiling and inheritance).
Use the thread lock to protect the POSIX thread attributes instead of
the thread state lock. This makes it easier to change the thread
priority and keep the POSIX attributes consistent.
Fixes a false positive use of uninitialized variable warning.

Move the writes to Thread_Control::current_priority and
Thread_Control::real_priority into _Thread_Change_priority() under the
protection of the thread lock. Add a filter function to
_Thread_Change_priority() to enable specialized variants.

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.
