There is no reason the callers of these functions need to change the
returned string, so change the `char *` return types to `const char *`.
Update a few callers to also use `const char *`.

Now that defs.h, server.h and common-defs.h are included via the
`-include` option, it is no longer necessary for source files to include
them. Remove all the inclusions of these files I could find. Update
the generation scripts where relevant.

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.
gdbsupport/errors.h declares perror_with_name and leaves the
implementation to the clients.
However gdb and gdbserver's implementations are essentially the
same, resulting in unnecessary code duplication.
Fix this by implementing perror_with_name in gdbsupport. Add an
optional parameter for specifying the errno used to generate the
error message.
Also move the implementation of perror_string to gdbsupport since
perror_with_name requires it.

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.
Currently, if GDBserver hits some internal assertion, it exits with
error status, instead of aborting. This makes it harder to debug
GDBserver, as you can't just debug a core file if GDBserver fails an
assertion. I've had to hack the code to make GDBserver abort to debug
something several times before.
I believe the reason it exits instead of aborting, is to prevent
potentially littering the filesystem of smaller embedded targets with
core files. I think I recall Daniel Jacobowitz once saying that many
years ago, but I can't be sure. Anyhow, that seems reasonable to me.
Since we nowadays have a distinction between development and release
modes, I propose to make GDBserver abort on internal error if in
development mode, while keeping the status quo when in release mode.
Thus, after this patch, in development mode, you get:
$ ../gdbserver/gdbserver
../../src/gdbserver/server.cc:3711: A problem internal to GDBserver has been detected.
captured_main: Assertion `0' failed.
Aborted (core dumped)
$
while in release mode, you'll continue to get:
$ ../gdbserver/gdbserver
../../src/gdbserver/server.cc:3711: A problem internal to GDBserver has been detected.
captured_main: Assertion `0' failed.
$ echo $?
1
I do not think that this requires a separate configure switch.
A "--target_board=native-extended-gdbserver" run on Ubuntu 20.04 ends
up with:
=== gdb Summary ===
# of unexpected core files 29
...
for me, of which 8 are GDBserver core dumps, 7 more than without this
patch.

This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.
This commits the result of running gdb/copyright.py as per our Start
of New Year procedure...
gdb/ChangeLog
Update copyright year range in copyright header of all GDB files.
For the same reasons outlined in the previous patch, this patch renames
gdbserver source files to .cc.
I have moved the "-x c++" switch to only those rules that require it.
gdbserver/ChangeLog:
* Makefile.in: Rename source files from .c to .cc.
* %.c: Rename to %.cc.
* configure.ac: Rename server.c to server.cc.
* configure: Re-generate.
