cc67f780ec sim: info: convert verbose field to a bool
The verbose argument has always been an int treated as a bool, so
convert it to an explicit bool.  Further, update the API docs to
match the reality that the verbose value is actually used by some
of the internal modules.

d87bef3a7b Update year range in copyright notice of binutils files
The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.

11e25f766e sim: drop unused SIM_ADDR type [PR sim/7504]
Now that sim APIs either use 64-bit addresses all the time, or more
appropriate target-specific types, drop this now-unused 32-bit-only
address type.

63fd5b5dda sim: switch sim_{read,write} APIs to 64-bit all the time [PR sim/7504]
We've been using SIM_ADDR which has always been 32-bit.  This means
the upper 32-bit address range in 64-bit sims is inaccessible.  Use
64-bit addresses all the time since we want the APIs to be stable
regardless of the active arch backend (which can be 32 or 64-bit).

The length is also 64-bit because it's completely feasible to have
a program that is larger than 4 GiB in size/image/runtime.  Forcing
the caller to manually chunk those accesses up into 4 GiB at a time
doesn't seem useful to anyone.

d026e67ed4 sim: move register headers into sim/ namespace [PR sim/29869]
These headers define the register numbers for each port to implement
the sim_fetch_register & sim_store_register interfaces.  While gdb
uses these, the APIs are part of the sim, not gdb.  Move the headers
out of the gdb/ include namespace and into sim/ instead.

195064c8da sim: drop unused CORE_ADDR_TYPE
This hasn't been used by gdb in decades, and doesn't make sense with
a standalone sim program/library where the ABI is fixed.  So punt it
to simplify the code.

ee1cffd388 sim: common: change sim_{fetch,store}_register helpers to use void* buffers
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.

a2c5833233 Update year range in copyright notice of binutils files
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.

The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.

20a8e078cc sim: reorder header includes
We're including system headers after local headers in a bunch of
places, but this leads to conflicts when our local headers happen
to define symbols that show up in the system headers.

Use the more standard order of:
* config.h (via defs.h)
* system headers
* local library headers (e.g. bfd & libiberty)
* sim specific headers

8cfc9a1895 sim: callback: expose argv & environ
Pass the existing strings data to the callbacks so that common
libgloss syscalls can be implemented (which we'll do shortly).

9335d9f823 sim: rename ChangeLog files to ChangeLog-2021
Now that ChangeLog entries are no longer used for sim patches,
this commit renames all relevant sim ChangeLog to ChangeLog-2021,
similar to what we would do in the context of the "Start of New
Year" procedure.

The purpose of this change is to avoid people merging ChangeLog
entries by mistake when applying existing commits that they are
currently working on.

Also throw in a .gitignore entry to keep people from adding new
ChangeLog files anywhere in the sim tree.

a1d9117f94 sim: callback: add printf attributes
This helps these funcs get printf format checking coverage.

The sim-io.c hack as a result is a bit unfortunate, but the compiler
throws warnings when printing with empty strings.  In this one case,
we actually want that due to the side-effect of the callback halting
execution for us.

bdedb2d21b sim: callback: extend syscall interface to handle 7 args
The Linux syscall interface, depending on architecture, handles up to
7 arguments.  Extend the callback API to handle those.

d394a6efed sim: callback: add a kill interface
This will make it easier to emulate the syscall.  If the kill target
is the sim itself, don't do anything.  This forces the higher layers
to make a decision as to how to handle this event: like halting the
overall engine process.

c45cffdbe1 sim: callback: add a getpid interface
Rather than hit the OS interface directly, use the existing callback
layer so the instantiator can decide behavior.

2fbe9507bf sim: callback: convert FS interfaces to 64-bit
Rather than rely on off_t being the right size between the host &
target, have the interface always be 64-bit.  We can figure out if
we need to truncate when actually outputting it to the right target.

We require C11 now, so no need for these pre-ANSI C hacks.
PTR is simply void*, so use that directly.

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.
