When running black to format Python files, files with extension .py.in
are ignored, because they don't end in .py. Add a pyproject.toml file
to instruct black to pick up these files too.

gdb: add owner-related methods to struct type
two fields of struct maint_type were renamed. 'flag_objfile_owned'
became 'm_flag_objfile_owned' and 'owner' became 'm_owner'. Update
our python helper script to take this into account.
I've added a basic test that uses the self-test framework to load the
pretty printers, and print a type.
The test relies on stopping in GDB's `value_print` function.
gdb/ChangeLog:
* gdb-gdb.py.in (StructMainTypePrettyPrinter) <owner_to_string>:
Updated fields names flag_objfile_owned to m_flag_objfile_owned,
and owner to m_owner.
gdb/testsuite/ChangeLog:
* gdb.gdb/python-helper.exp: New file.

In struct dynamic_prop the members kind and data were renamed to m_kind and
m_data.
And flag_upper_bound_is_count is actually in bounds directly, not in its
high member.

This commit introduces a new kind of type, meant to describe
fixed-point types, using a new code added specifically for
this purpose (TYPE_CODE_FIXED_POINT).
It then adds handling of fixed-point base types in the DWARF reader.
And finally, as a first step, this commit adds support for printing
the value of fixed-point type objects.
Note that this commit has a known issue: Trying to print the value
of a fixed-point object with a format letter (e.g. "print /x NAME")
causes the wrong value to be printed because the scaling factor
is not applied. Since the fix for this issue is isolated, and
this is not a regression, the fix will be made in a pach of its own.
This is meant to simplify review and archeology.
Also, other functionalities related to fixed-point type handling
(ptype, arithmetics, etc), will be added piecemeal as well, for
the same reasons (faciliate reviews and archeology). Related to this,
the testcase gdb.ada/fixed_cmp.exp is adjusted to compile the test
program with -fgnat-encodings=all, so as to force the use of GNAT
encodings, rather than rely on the compiler's default to use them.
The intent is to enhance this testcase to also test the pure DWARF
approach using -fgnat-encodings=minimal as soon as the corresponding
suport gets added in. Thus, the modification to the testcase is made
in a way that it prepares this testcase to be tested in both modes.

Commit 314ad88df63c ("Use type_instance_flags more throughout") changed
the name of field type::instance_flags to type::m_instance_flags. It
however missed changing it in the gdb-gdb.py.in file, which results in
this when trying to use the pretty-printer:
(top-gdb) p *val.type
Traceback (most recent call last):
File "/home/smarchi/build/binutils-gdb/gdb/gdb-gdb.py", line 116, in to_string

This patch fixes it.

I noticed that trying to print the contents of a struct main_type
would fail when the type was a TYPE_CODE_RANGE:
(gdb) p *type.main_type
$1 = Python Exception <class 'gdb.error'> There is no member named low_undefined.:
And indeed, Python is right, fields "low_undefined" has been removed
from struct range_bounds back in ... 2014! It was done when we introduced
dynamic bounds handling. This patch fixes gdb-gdb.py.in according to
the new structure.
gdb/ChangeLog:
* gdb-gdb.py.in (StructMainTypePrettyPrinter.bound_img): New method.
(StructMainTypePrettyPrinter.bounds_img): Use new "bound_img"
method to compute the bounds of range types. Also print "[evaluated]"
if the bounds' values come from a dynamic evaluation.

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 has been removed recently.

Python 3 doesn't use __cmp__ to order objects, it uses __lt__. Because
of this, we get this exception when trying to pretty-print "type"
objects:
I tested it with Python 2.7 as well.
gdb/ChangeLog:
* gdb-gdb.py.in (TypeFlag) <__cmp__>: Remove.
<__lt__>: Add.

I have thought for a long time how nice it would be to have cool pretty
printers for GDB's internal types. Well, turns out there are few
already in gdb-gdb.py! Unfortunately, if you build GDB outside of the
source directory, that file never gets loaded. top-gdb will look for a
file called
../path/to/build/gdb/gdb-gdb.py
but that file is in the source directory at
../path/to/src/gdb/gdb-gdb.py
This patch makes it so we copy it to the build directory, just like we
do for gdb-gdb.gdb. With this, I can at least see the file getting
automatically loaded:
(top-gdb) info pretty-printer
global pretty-printers:
builtin
mpx_bound128
objfile /home/emaisin/build/binutils-gdb/gdb/gdb pretty-printers:
type_lookup_function
I noticed that running "make" didn't re-generate gdb-gdb.py from
gdb-gdb.py.in. That's because it's copied when running the configure
script and that's it. I added a rule in the Makefile for that (and for
gdb-gdb.gdb too) and added them as a dependency to the "all" target.
gdb/ChangeLog:
* gdb-gdb.py: Move to...
* gdb-gdb.py.in: ... here.
* configure.ac (AC_CONFIG_FILES): Add gdb-gdb.py.
* Makefile.in (all): Add gdb-gdb.gdb and gdb-gdb.py as
dependencies.
(distclean): Remove gdb-gdb.py when cleaning.
(gdb-gdb.py, gdb-gdb.gdb): New rules.
* configure: Re-generate.
