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.

# This test spawns a few threads that constantly trip on a breakpoint
|
|
# that does not cause a user-visible stop. While one of those
|
|
# breakpoints is being handled, the main thread exits the whole
|
|
# process. The result is that the current thread for which GDB is
|
|
# handling the event disappears too and any attempt to access
|
|
# register/memory now errors out. GDB and GDBserver should be able to
|
|
# handle this scenario gracefully.
