214d8edd18 score: Add self-contained mutex implementation 
This mutex implementation uses a thread priority queue with a simple
priority inheritance mechanism (similar to the object based mutexes).
The storage space must be supplied by the user (16 bytes on 32-bit
targets).

0e3c59d65c score: Use a plain ticket lock for thread locks 
This enables external libraries to use thread locks since they are
independent of the actual RTEMS build configuration, e.g. profiling
enabled or disabled.

10e32a2634 score: Add potpourri lock statistics 
These SMP lock statistics are used for all lock objects that lack a
storage space for the statistics.  Examples are lock objects used in
external libraries which are independent of the actual RTEMS build
configuration.

e709aa8522 score: Move wait flag update to tq extract 
This makes it possible to use _Thread_queue_Extract_locked() for barrier
operations which extract all threads on the queue in one critical
section.

d7665823b2 score: Introduce Thread_queue_Heads 
Move the storage for the thread queue heads to the threads.  Each thread
provides a set of thread queue heads allocated from a dedicated memory
pool.  In case a thread blocks on a queue, then it lends its heads to
the queue.  In case the thread unblocks, then it takes a free set of
threads from the queue.  Since a thread can block on at most one queue
this works.  This mechanism is used in FreeBSD.  The motivation for this
change is to reduce the memory demands of the synchronization objects.
On a 32-bit uni-processor configuration the Thread_queue_Control size is
now 8 bytes, compared to 64 bytes in RTEMS 4.10 (other changes reduced
the size as well).

e273501233 score: Introduce Thread_queue_Queue 
Separate the thread queue heads and lock from the operations.  This
enables the support for light weight objects which only support one
queuing discipline.

d6c67ad526 bsp/tms570: skipped 32bit field definitions and corrected single bit fields

whole registers. In addition, BSP_FLD32 does not work right

602e395b4d bsp/tms570: fix get time resolution after infrastructure change to timecounter. 
The update fixes breakage of TMS570 support after Alexander Krutwig
switch of RTEMS time read to timecounter mechanism

bsps: Convert clock drivers to use a timecounter

Mechanism to specify odd (non 1 Mhz) time base update frequencies
implemented after objections of  Martin Galvan.

Code is adjusted to convert RTEMS configuration parameter
microseconds_per_tick to such odd base if
TMS570_PREFERRED_TC_FREQUENCY is specified appropriately.
