This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

/* Convert SIM_SIGFOO to SIGFOO.

What to do when the host doesn't have SIGFOO is handled on a case by case
|
|
basis. Generally, in the case of passing a value back to gdb, we want gdb
|
|
to not think the process has died (so it can be debugged at the point of
|
|
failure). */
