6df01ab8ab sim: switch config.h usage to defs.h
The defs.h header will take care of including the various config.h
headers.  For now, it's just config.h, but we'll add more when we
integrate gnulib in.

This header should be used instead of config.h, and should be the
first include in every .c file.  We won't rely on the old behavior
where we expected files to include the port's sim-main.h which then
includes the common sim-basics.h which then includes config.h.  We
have a ton of code that includes things before sim-main.h, and it
sometimes needs to be that way.  Creating a dedicated header avoids
the ordering mess and implicit inclusion that shows up otherwise.

df68e12b3b sim: create header namespace
The gdb/callback.h & gdb/remote-sim.h headers have nothing to do with
gdb and are really definitions for the libsim API under the sim/ tree.
While gdb uses those headers as a client, it's not specific to it.  So
create a new sim/ namespace and move the headers there.

f08708cbf5 sim: add ATTRIBUTE_PRINTF / ATTRIBUTE_NULL_PRINTF where necessary
I finally got the all-targets sim building with Clang, these are all the
instances where an ATTRIBUTE_PRINTF or ATTRIBUTE_NULL_PRINTF attribute
needed to be added to avoid errors like:

    /home/simark/src/binutils-gdb/sim/aarch64/../common/sim-profile.c:464:19: error: format string is not a string literal [-Werror,-Wformat-nonliteral]
        vfprintf (fp, fmt, ap);
                      ^~~
There are more fixes needed to get everything building, but adding these
attributes is trivial enough, so I send them all in a single patch.

Adding the format attributes introduces some format string errors when
building with GCC (because now format strings are checked), so
corresponding changes are needed to avoid breaking the build.  Other
than simple format string specified changes, there is this one:

    /home/simark/src/binutils-gdb/sim/aarch64/../common/hw-events.c: In function 'hw_event_queue_schedule':
    /home/simark/src/binutils-gdb/sim/aarch64/../common/hw-events.c:95:15: error: too many arguments for format [-Werror=format-extra-args]
       95 |         NULL, dummy);
          |               ^~~~~

We can fix it and avoid using a dummy variable by simply calling
hw_event_queue_schedule_tracef instead of
hw_event_queue_schedule_vtracef.

	* armdefs.h (ARMul_ConsolePrint): Use format attribute.
	* wrapper.c (op_printf): Likewise.

d89a87ba3c sim: bfin: move option inits to respective modules
Now that modules can self declare their own init funcs, change the mmu
and mach logic to use it.  We don't need to export the option symbols
or specifically call this logic from the sim_open function anymore.

4c0d76b9c4 sim: watchpoints: use common sim_pc_get
Few arches implement STATE_WATCHPOINTS()->pc while all of them implement
sim_pc_get.  Lets switch the sim-watch core for monitoring pc events to
the sim_pc_get API so this module works for all ports, and then we can
delete this old back channel of snooping in the port's cpu state -- the
code needs the pointer to the pc storage so that it can read out bytes
and compare them to the watchrange.

This also fixes the logic on multi-cpu sims by removing the limitation
of only being able to watch CPU0's state.

d4e3adda12 sim: watchpoints: change sizeof_pc to sizeof(sim_cia)
Existing ports already have sizeof_pc set to the same size as sim_cia,
so simply make that part of the core code.  We already assume this in
places by way of sim_pc_{get,set}, and this is how it's documented in
the sim-base.h API.

There is code to allow sims to pick different register word sizes from
address sizes, but most ports use the defaults for both (32-bits), and
the few that support multiple register sizes never change the address
size (so address defaults to register).  I can't think of any machine
where the register hardware size would be larger than the address word
size either.  We have ABIs that behave that way (e.g. x32), but the
hardware is still equivalent register sized.

0ede24f2c4 sim: common: add align_{up,down} to match gdb
We have ALIGN_{8,16,PAGE} and FLOOR_PAGE macros (where PAGE is defined as
4k) which were imported from the ppc sim.  But no other sim utilizes these
and hardcoding the sizes in the name is a bit limiting.

Let's delete these and import the two general macros that gdb uses:
	align_up(addr, bytes)
	align_down(addr, bytes)

This in turn allows us to cut over the Blackfin code immediately.

This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

0e9672991e sim: standardize sim_create_inferior handling of argv a bit more
For targets that process argv in sim_create_inferior, improve the code:
- provide more details in the comment
- make the check for when to re-init more robust
- clean out legacy sim_copy_argv code

This will be cleaned up more in the future when we have a common inferior
creation function, but at least help new ports get it right until then.

6e4f085c7f sim: sim-close: unify sim_close logic
Other than the nice advantage of all sims having to declare one fewer
common function, this also fixes leakage in pretty much every sim.
Many were not freeing any resources, and a few were inconsistent as
to the ones they did.  Now we have a single module that takes care of
all the logic for us.

Most of the non-cgen based ones could be deleted outright.  The cgen
ones required adding a callback to the arch-specific cleanup func.
The few that still have close callbacks are to manage their internal
state.

We do not convert erc32, m32c, ppc, rl78, or rx as they do not use
the common sim core.
