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.

d5a71b1131 sim: cgen: move cgen_cpu_max_extra_bytes logic into the common code
Every arch handles this the same way, so move it to the common code.
This will also make unifying the sim_cpu structure easier.

42a4f53d2b Update copyright year range in all GDB files.
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.

	Update copyright year range in all GDB files.

dcc31d286a FT32: support for FT32B processor - part 2/2
FT32B is a new FT32 family member.
This patch adds support for the compressed instructions to gdb and sim.

gdb/ChangeLog:
        * ft32-tdep.c (ft32_fetch_instruction): New function.
        (ft32_analyze_prologue): Use ft32_fetch_instruction().

sim/ChangeLog:
        * ft32/interp.c (step_once): Add ft32 shortcode decoder.

3b4b0a629a FT32: support for FT32B processor - part 1
FT32B is a new FT32 family member. It has a code
compression scheme, which requires the use of linker
relaxations. The change is quite large, so submission
is in several parts.

Part 1 adds a 15-bit instruction field, and CPU-specific functions for
the code compression that are used in binutils and GDB.

77cf2ef5dc sim: parse_args: display getopt error ourselves
Fix a long standing todo where we let getopt write directly to stderr
when an invalid option is passed.  Use the sim io funcs instead as they
go through the filtered callbacks that gdb wants.

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.

71c34ca7a0 sim: ft32: correctly simulate PM write port
The FT32 simulator was not correctly simulating the behavior of the
program memory (PM) write port.  When it is locked, writes to the
data register do nothing.

bcd68f9e44 sim: ft32: add character input port
The FT32 simulator has character output, of course. This patch
adds character input, which lets the simulator run interactive
FT32 applications, e.g. language interpreters.

034685f9ce sim: replace CIA_{GET,SET} with CPU_PC_{GET,SET}
The CIA_{GET,SET} macros serve the same function as CPU_PC_{GET,SET}
except the latter adds a layer of indirection via the sim state.  This
lets models set up different functions at runtime and doesn't reach so
directly into the arch-specific cpu state.

It also doesn't make sense to have two sets of macros that do exactly
the same thing, so lets standardize on the one that gets us more.
