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.
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.
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.
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.

Rather than rely on time_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.
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.
