This updates the copyright headers to include 2025. I did this by
running gdb/copyright.py and then manually modifying a few files as
noted by the script.

This patch is the result of running check-include-guards.py on the
current tree. Running it a second time causes no changes.

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.

Add new function debuginfod_section_query. This function queries
debuginfod servers for an individual ELF/DWARF section associated with
a given build-id.

open_source_file relies on errno to communicate the reason for a missing
source file.
open_source_file may also call debuginfod_find_source. It is possible
for debuginfod_find_source to set errno to a value unrelated to the
reason for a failed download.
This can result in bogus error messages being reported as the reason for
a missing source file. The following error message should instead be
"No such file or directory":
Temporary breakpoint 1, 0x00005555556f4de0 in main ()
(gdb) list
Downloading source file /usr/src/debug/glibc-2.36-8.fc37.x86_64/elf/<built-in>
1 /usr/src/debug/glibc-2.36-8.fc37.x86_64/elf/<built-in>: Directory not empty.
Fix this by having open_source_file return a negative errno if it fails
to open a source file. Use this value to generate the error message
instead of errno.

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.

Add debuginfod support to core_target::build_file_mappings and
locate_exec_from_corefile_build_id to enable the downloading of
missing executables and shared libraries referenced in core files.
Also add debuginfod support to solib_map_sections so that previously
downloaded shared libraries can be retrieved from the local debuginfod
cache.
When core file shared libraries are found locally, verify that their
build-ids match the corresponding build-ids found in the core file.
If there is a mismatch, attempt to query debuginfod for the correct
build and print a warning if unsuccessful:
warning: Build-id of /lib64/libc.so.6 does not match core file.
Also disable debuginfod when gcore invokes gdb. Debuginfo is not
needed for core file generation so debuginfod queries will slow down
gcore unnecessarily.

debuginfod is a lightweight web service that indexes ELF/DWARF debugging
resources by build-id and serves them over HTTP.
This patch enables GDB to query debuginfod servers for separate debug
files and source code when it is otherwise not able to find them.
GDB can be built with debuginfod using the --with-debuginfod configure
option.
This requires that libdebuginfod be installed and found at configure time.
debuginfod is packaged with elfutils, starting with version 0.178.
For more information see https://sourceware.org/elfutils/.
Tested on x86_64 Fedora 31.
