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.

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.

gdb/ChangeLog:

        Update copyright year range in all GDB files.

While working on my other scripts to deal with gdb headers, I noticed
that some files were missing include guards.  I wrote a script to add
the missing ones, but found that using the obvious names for the
guards ran into clashes -- for example, gdb/nat/linux-nat.h used
"LINUX_NAT_H", but this was also the script's choice for
gdb/linux-nat.h.

So, I changed the script to normalize all include guards in gdb.  This
patch is the result.

As usual the script is available here:

    https://github.com/tromey/gdb-refactoring-scripts

Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the
buildbot.

This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

gdb/ChangeLog:

	Update copyright year range in all GDB files.

gdb/ChangeLog:

        Update copyright year range in all GDB files

Remove gdb.BtraceFunctionCall and replace by gdb.FunctionSegment.  Additionally,
rename prev_segment and next_segment to prev and next.

Remove gdb.BtraceInstruction and replace by gdb.RecordInstruction.

This patch implements the gdb.Record Python object methods and fields for
record target btrace.  Also, implement a stub for record target full.
