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.

New in this version:

 - Rebase on master, fix a few more issues that appeared.

python-internal.h contains a number of macros that helped make the code
work with both Python 2 and 3.  Remove them and adjust the code to use
the Python 3 functions.

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.

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.

	Update copyright year range in all GDB files.

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

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.

gdb/ChangeLog:

        Update copyright year range in all GDB files.

This patch modifies the unwinder (sniffer) defined in
py-recurse-unwind.py so that, depending upon the value of one of its
class variables, it will take different paths through the code,
testing different functionality.

The original test attempted to obtain the value of an undefined
symbol.

This somewhat expanded test checks to see if 'pc' can be read via
gdb.PendingFrame.read_register() and also via gdb.parse_and_eval().

gdb/testsuite/ChangeLog:

	* gdb.python/py-recurse-unwind.c (main): Add loop.
	* gdb.python/py-recurse-unwind.py (TestUnwinder): Add calls
	to read_register() and gdb.parse_and_eval().  Make each code
	call a separate case that can be individually tested.
	* gdb.python/py-recurse-unwind.exp (cont_and_backtrace): New
	proc. Call cont_and_backtrace for each of the code paths that
	we want to test in the unwinder.

This test case verifies that GDB will not attempt to invoke a python
unwinder recursively.

At the moment, the behavior exhibited by GDB looks like this:

    (gdb) source py-recurse-unwind.py
    Python script imported
    (gdb) b ccc
    Breakpoint 1 at 0x4004bd: file py-recurse-unwind.c, line 23.
    (gdb) run
    Starting program: py-recurse-unwind
    TestUnwinder: Recursion detected - returning early.
    TestUnwinder: Recursion detected - returning early.
    TestUnwinder: Recursion detected - returning early.
    TestUnwinder: Recursion detected - returning early.

    Breakpoint 1, ccc (arg=<unavailable>) at py-recurse-unwind.c:23
    23      }
    (gdb) bt
    #-1 ccc (arg=<unavailable>) at py-recurse-unwind.c:23
    Backtrace stopped: previous frame identical to this frame (corrupt stack?)

[I've shortened pathnames for easier reading.]

The desired / expected behavior looks like this:

    (gdb) source py-recurse-unwind.py
    Python script imported
    (gdb) b ccc
    Breakpoint 1 at 0x4004bd: file py-recurse-unwind.c, line 23.
    (gdb) run
    Starting program: py-recurse-unwind

    Breakpoint 1, ccc (arg=789) at py-recurse-unwind.c:23
    23      }
    (gdb) bt
    #0  ccc (arg=789) at py-recurse-unwind.c:23
    #1  0x00000000004004d5 in bbb (arg=456) at py-recurse-unwind.c:28
    #2  0x00000000004004ed in aaa (arg=123) at py-recurse-unwind.c:34
    #3  0x00000000004004fe in main () at py-recurse-unwind.c:40

Note that GDB's problems go well beyond the fact that it invokes the
unwinder recursively.  In the process it messes up some internal state
(the frame stash) leading to display of (only) the sentinel frame in
the backtrace.

gdb/testsuite/ChangeLog:

	* gdb.python/py-recurse-unwind.c: New file.
	* gdb.python/py-recurse-unwind.py: New file.
	* gdb.python/py-recurse-unwind.exp: New file.

One of the last checks update_breakpoints_after_exec does while looping
over the list of breakpoints is check that the breakpoint has a valid
location spec. It uses event_location_empty_p to check if the location spec
is "empty", and if it is, the breakpoint is deleted.

momentary_breakpoint types rely on setting the breakpoint structure's
location spec to NULL, thereby causing an update to delete the breakpoint.
However, event_location_empty_p assumed that locations were never NULL.
As a result, GDB would crash dereferencing a NULL pointer whenever
update_breakpoints_after_exec would encounter a momentary_breakpoint.

This patch creates a new wrapper/helper function which tests that the given
breakpoint's location spec is non-NULL and if it is not "empty"
or "unspecified."

gdb/ChangeLog

	PR breakpoints/19546
	* breakpoint.c (breakpoint_event_location_empty_p): New function.
	(update_breakpoints_after_exec, bkpt_re_set): Use this new function
	instead of event_location_empty_p.

Two modifications:

  2. The use of a single year range, instead of potentially multiple
     year ranges, as approved by the FSF.
