* libgnarl/s-taprop__mingw.adb: On Windows, initialize the thead handle
only for foreign threads. We initialize the thread handle only if not
yet initialized. This happens in Enter_Task for foreign threads only.
But for native threads (Ada tasking) we do want to keep the real
handle (from Create_Task) to be able to free the corresponding
resources in Finalize_TCB (CloseHandle).

* sem_attr.adb (Analyze_Attribute): Default initialize P_Type,
P_Base_Type.
(Error_Attr_P): Fix name in pragma No_Return.
(Unexpected_Argument): Add pragma No_Return.
(Placement_Error): Add pragma No_Return.

* exp_disp.adb (Elab_Flag_Needed): Elaboration flag not needed when the
dispatch table is statically built.
(Make_DT): Declare constant the Interface_Table object associated with
an statically built dispatch table. For this purpose the Offset_To_Top
value of each interface is computed using the dummy object.
* exp_ch3.adb (Build_Init_Procedure): Do not generate code initializing
the Offset_To_Top field of secondary dispatch tables when the dispatch
table is statically built.
(Initialize_Tag): Do not generate calls to Register_Interface_Offset
when the dispatch table is statically built.
* doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
Document the new GNAT restriction Static_Dispatch_Tables.
* gnat_rm.texi: Regenerate.

* sem_aggr.adb (Resolve_Delta_Record_Aggregate): Reorder declarations
to avoid a dormant bug.

* init.c: Define missing __gnat_alternate_stack for QNX. Set it to 0,
as such capability is not available on the OS.
* link.c: Make sure linker options for QNX are correct.
* libgnarl/s-osinte__qnx.ads: Add some missing bindings to pthread.
* libgnarl/s-taprop__qnx.adb: New, derived from s-taprop__posix.adb. This brings
in particular a workaround with locks priority ceiling where a higher
priority task is allowed to lock a lower ceiling priority lock. This
also fixes the scheduling of FIFO tasks when the priority of a task is
lowered.
* libgnat/system-qnx-aarch64.ads: Fix priority ranges.

* erroutc.adb (Output_Error_Msgs): Justify CodePeer false positive
message.
* gnatbind.adb (Scan_Bind_Arg): Simplify test to remove always true
condition.
* namet.adb (Copy_One_Character): Add assumption for static analysis,
as knowledge that Hex(2) is in the range 0..255 is too complex for
CodePeer.
(Finalize): Add assumption for static analysis, as the fact that there
are symbols in the table depends on a global invariant at this point in
the program.
* set_targ.adb (Check_Spaces): Justify CodePeer false positive message.
* stylesw.adb (Save_Style_Check_Options): Rewrite to avoid test always
true.
