While GDB is still C++11, lets add a gdb::make_unique template
function that can be used to create std::unique_ptr objects, just like
the C++14 std::make_unique.
If GDB is being compiled with a C++14 compiler then the new
gdb::make_unique function will delegate to the std::make_unique. I
checked with gcc, and at -O1 and above gdb::make_unique will be
optimised away completely in this case.
If C++14 (or later) becomes our minimum, then it will be easy enough
to go through the code and replace gdb::make_unique with
std::make_unique later on.
I've make use of this function in all the places I think this can
easily be used, though I'm sure I've probably missed some.
Should be no user visible changes after this commit.

Remove the breakpoint_pointer_iterator layer. Adjust all users of
all_breakpoints and all_tracepoints to use references instead of
pointers.

The print_it method itself is const. In a subsequent patch, the
locations that come out of a const breakpoint will be const as well. It
will therefore be needed to make the last_loc output parameter const as
well. Make that change now to reduce the size of the following patches.

Some implementations of breakpoint::check_status and
breakpoint::print_it do this:
struct breakpoint *b = bs->breakpoint_at;
bs->breakpoint_at is always the same as `this` (we can get convinced by
looking at the call sites of check_status and print_it), so it would
just be clearer to access fields through `this` instead.

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 introduces a catchpoint class that is used as the base class for
all catchpoints. init_catchpoint is rewritten to be a constructor
instead.
This changes the hierarchy a little -- some catchpoints now inherit
from base_breakpoint whereas previously they did not. This isn't a
problem, as long as re_set is redefined in catchpoint.
At this point, all implementations of breakpoints use the vtable. So,
we can now remove most function pointers from breakpoint_ops and
switch to using methods directly in the callers. Only the two "static
virtual" methods remain in breakpoint_ops.
This changes breakpoint_ops::print_one to return bool, and updates all
the implementations and the caller. The caller is changed so that a
NULL check is no longer needed -- something that will be impossible
with a real method.
The "catch load" code is reasonably self-contained, and so this patch
moves it out of breakpoint.c and into a new file, break-catch-load.c.
One function from breakpoint.c, print_solib_event, now has to be
exposed, but this seems pretty reasonable.
