This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.
Now that all ports have migrated to the new framework, drop support
for the old sim_cpu_base layout. There's a lot of noise here, so
it's been split into a dedicated commit.
Currently all ports have to declare sim_cpu themselves in their
sim-main.h and then embed the common sim_cpu_base in it. This
dynamic makes it impossible to share common object code among
multiple ports because the core data structure is always different.
Let's invert this relationship: common code declares sim_cpu, and
the port uses the new arch_data field for its per-cpu state.
This is the first in a series of changes: it adds a define to select
between the old & new layouts, then converts all the ports that don't
need custom state over to the new layout. This includes mn10300 that,
while it defines custom fields in its cpu struct, never uses them.
When reading/writing arbitrary data to the system's memory, the unsigned
char pointer type doesn't make that much sense. Switch it to void so we
align a bit with standard C library read/write functions, and to avoid
having to sprinkle casts everywhere.
Clang generates a warning if the format string of a printf-like function is
not a literal ("-Wformat-nonliteral"). On the default configuration, it
causes a build failure (unless "--disable-werror" is specified).
To avoid warnings on the printf-like wrapper, it requires proper
__attribute__((format)) and we have ATTRIBUTE_PRINTF macro for this reason.
This commit adds ATTRIBUTE_PRINTF to a printf-like function.
This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.

gdb/ChangeLog
Update copyright year range in copyright header of 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.
gdb/ChangeLog:
Update copyright year range in all GDB files.
This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
Rather than include this for some targets, set it up so we can build it
all the time via the common code. This makes it easier for targets to
opt into it when they're ready, increases build coverage, and allows us
to centralize much of the logic.
We also get to delete tconfig.h from two more targets -- they were
setting WITH_DEVICES to 0 which has the same behavior as not defining
it at all.
While the SIM_HAVE_MODEL knob is gone, we now have WITH_MODEL_P, but it
is only used by the common sim-model code. We use it to declare dummy
model lists when the arch hasn't created its own.
The "MACH" and "MODEL" names are a bit generic and collide with symbols
used by other sections of code (like h8300's opcodes). Since these are
sim-specific types, they really should have a "SIM_" prefix.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
