This version has been tested on the sort multithreaded application  
for TSAR_IOB architectures ranging from 1 to 8 clusters. 
It fixes three bigs bugs: 
1) the dev_ioc device API has been modified: the dev_ioc_sync_read() 
and dev_ioc_sync_write() function use now extended pointers on the  
kernel buffer to access a mapper stored in any cluster. 
2) the hal_uspace API has been modified: the hal_copy_to_uspace() 
and hal_copy_from_uspace() functions use now a (cxy,ptr) couple 
to identify the target buffer (equivalent to an extended pointer. 
3) an implementation bug has been fixed in the assembly code contained  
in the hal_copy_to_uspace() and hal_copy_from_uspace() functions.
