d50acdbb6c score: Add local context to SMP lock API 
Add a local context structure to the SMP lock API for acquire and
release pairs.  This context can be used to store the ISR level and
profiling information.  It may be later used to enable more
sophisticated lock algorithms, e.g. MCS locks.

There is only one lock that cannot be used with a local context.  This
is the per-CPU lock since here we would have to transfer the local
context through a context switch which is very complicated.

ae88aa7927 sapi: Use one SMP lock for all chains 
This partially reverts commit 1215fd4d94.

In order to support profiling of SMP locks and provide a future
compatible SMP locks API it is necessary to add an SMP lock destroy
function.  Since the commit above adds an SMP lock to each chain control
we would have to add a rtems_chain_destroy() function as well.  This
complicates the chain usage dramatically.  Thus revert the patch above.
A global SMP lock for all chains is used to implement the protected
chain operations.

Advantages:

* The SAPI chain API is now identical on SMP and non-SMP
  configurations.

* The size of the chain control is reduced and is then equal to the
  Score chains.

* The protected chain operations work correctly on SMP.

Disadvantage:

* Applications using many different chains and the protected operations
  may notice lock contention.

The chain control size drop is a huge benefit (SAPI chain controls are
66% larger than the Score chain controls).  The only disadvantage is not
really a problem since these applications can use specific interrupt
locks and unprotected chain operations to avoid this issue.
