User Extension API for the TCB extensions array.

[Chris Johns]

The User Extensions API needs to be extended to provide controlled access to the extensions array in the TCB.

The following is required:

rtems_status_code
rtems_extension_get_var(rtems_id id,

rtems_id task,
void var);

void* rtems_extension_self_get_var(int index);

The last one must be an inline/macro. The use of the extension id should be looked at verses the use of an index.

Note, this API is needed to resolve PR189 plus remove taskvars from RTEMS. RPC and the capture engine also require it.
