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) help save gdb-index
Save a gdb-index file.
Usage: save gdb-index [-dwarf-5] DIRECTORY
No options create one file with .gdb-index extension for pre-DWARF-5
compatible .gdb_index section. With -dwarf-5 creates two files with
extension .debug_names and .debug_str for DWARF-5 .debug_names section.
------------------------------------------------------------------------------
But gdb-add-index command provided no way how to pass the -dwarf-5 option.

* contrib/gdb-add-index.sh ($dwarf5): New, use it.
This adds a new "-dwarf-5" switch to "save gdb-index" that makes it
generate index files with DWARF-5 .debug_names/.debug_str sections
instead of GDB's own .gdb_index.
We should probably add a command line option to
contrib/gdb-add-index.sh (incl. cc-with-tweaks.sh) for the new
-dwarf-5 GDB option, and a new target board to make it more convenient
to exercise this. To be done later.
