* s-osinte-posix.adb, s-osinte-linux.ads, s-osinte-freebsd.adb,
s-osinte-freebsd.ads, s-osinte-solaris-posix.ads, s-osinte-hpux.ads,
s-osinte-darwin.adb, s-osinte-darwin.ads, s-osinte-lynxos-3.ads,
s-osinte-lynxos-3.adb (To_Target_Priority): New function maps from
System.Any_Priority to a POSIX priority on the target.
* system-linux-ia64.ads:
Extend range of Priority types on Linux to use the whole range made
available by the system.
* s-osinte-aix.adb, s-osinte-aix.ads (To_Target_Priority): New
function maps from System.Any_Priority to a POSIX priority on the
target.
(PTHREAD_PRIO_PROTECT): Set real value.
(PTHREAD_PRIO_INHERIT): Now a function.
(SIGCPUFAIL): New signal.
(Reserved): Add SIGALRM1, SIGWAITING, SIGCPUFAIL, since these signals
are documented as reserved by the OS.
* system-aix.ads: Use the full range of priorities provided by the
system on AIX.
* s-taprop-posix.adb: Call new function To_Target_Priority.
(Set_Priority): Take into account Task_Dispatching_Policy and
Priority_Specific_Dispatching pragmas when determining if Round Robin
must be used for scheduling the task.
* system-linux-x86_64.ads, system-linux-x86.ads,
system-linux-ppc.ads: Extend range of Priority types on Linux to use
the whole range made available by the system.
* s-taprop-vms.adb, s-taprop-mingw.adb, s-taprop-irix.adb,
s-taprop-tru64.adb, s-taprop-linux.adb, s-taprop-hpux-dce.adb,
s-taprop-lynxos.adb (Finalize_TCB): invalidate the stack-check cache
when deallocating the TCB in order to avoid potential references to
deallocated data.
(Set_Priority): Take into account Task_Dispatching_Policy and
Priority_Specific_Dispatching pragmas when determining if Round Robin
or FIFO within priorities must be used for scheduling the task.
* s-taprop-vxworks.adb (Enter_Task): Store the user-level task id in
the Thread field (to be used internally by the run-time system) and the
kernel-level task id in the LWP field (to be used by the debugger).
(Create_Task): Reorganize to unify the calls to taskSpawn into a single
instance, and propagate the current task options to the spawned task.
(Set_Priority): Take into account Priority_Specific_Dispatching pragmas.
(Initialize): Set Round Robin dispatching when the corresponding pragma
is in effect.
