9f9aa85206 gdb: Make python display_hint None handling defined behaviour
The documentation say that the display_hint method must return a
string to serve as a display hint, and then goes on to list some
acceptable strings.

However, if we don't supply the display_hint method then we get a
default display style behaviour and there's currently no way (in the
python api) to force this default behaviour.

The guile api allows #f to be used in order to force the default
display style behaviour, and this is documented.

Currently, using None in the python api also forces the default
display behaviour.

This commit extends the documentation to make returning None from the
display_hint method an official mechanism by which the user can get
the default display style.

I've extended one of the existing tests to cover this case.

gdb/doc/ChangeLog:

	* python.texi (Pretty Printing API): Document use of None for the
	display_hint.

gdb/testsuite/ChangeLog:

	* gdb.python/py-prettyprint.c (struct container) <is_map_p>: New

42a4f53d2b 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.

332cf4c925 Allow a pretty-printer without a to_string method
PR python/16047 points out that, while the documentation says that the
to_string method is optional for a pretty-printer, the code disagrees
and throws an exception.  This patch fixes the problem.  varobj is
already ok here.

Tested on x86-64 Fedora 26.

0625771b9e MI: Allow non-raw varobj evaluation
Make the MI variable object expression evaluation, with the
-var-evaluate-expression command, recursively call pretty printers, to
match the output of normal expression printing.

Consider the following code:

        struct Foo { int val; };
        struct Wrapper { Foo foo; };

        int main() {
                Wrapper w;
                w.foo.val = 23;
        }

and this pretty printer file:

        import gdb.printing

        class FooPrinter:
          def __init__(self, val):
            self.val = val
          def to_string(self):
            return "Foo" + str(self.val["val"])

        class WrapperPrinter:
          def __init__(self, val):
            self.val = val
          def to_string(self):
            return self.val["foo"]

        test_printer = gdb.printing.RegexpCollectionPrettyPrinter("test")
        test_printer.add_printer('Foo', '^Foo$', FooPrinter)
        test_printer.add_printer('Wrapper', '^Wrapper$', WrapperPrinter)

        gdb.printing.register_pretty_printer(None, test_printer)

Setting a breakpoint at the end of the function, we call the following commands:

        -enable-pretty-printing
        ^done

        -var-create var_w @ w
        ^done,name="var_w",numchild="0",value="{val = 23}",type="Wrapper",dynamic="1",has_more="0"
        -var-create var_w_foo @ w.foo
        ^done,name="var_w_foo",numchild="0",value="Foo23",type="Foo",dynamic="1",has_more="0"

        -var-evaluate-expression var_w
        ^done,value="{val = 23}"
        -var-evaluate-expression var_w_foo
        ^done,value="Foo23"

        -data-evaluate-expression w
        ^done,value="Foo23"
        -data-evaluate-expression w.foo
        ^done,value="Foo23"

So, in the -var-evaluate-expression var_w case, we print the "raw" value
of w.foo, while in the -data-evaluate-expression w case, we print the
pretty printed w.foo value. After this patch, all of the above print
"Foo23".

c973d0aa4a Fix type casts losing typedefs and reimplement "whatis" typedef stripping
(Ref: https://sourceware.org/ml/gdb/2017-06/msg00020.html)

Assuming int_t is a typedef to int:

 typedef int int_t;

gdb currently loses this expression's typedef:

 (gdb) p (int_t) 0
 $1 = 0
 (gdb) whatis $1
 type = int

or:

 (gdb) whatis (int_t) 0
 type = int

or, to get "whatis" out of the way:

 (gdb) maint print type (int_t) 0
 ...
 name 'int'
 code 0x8 (TYPE_CODE_INT)
 ...

This prevents a type printer for "int_t" kicking in, with e.g.:

 (gdb) p (int_t) 0

From the manual, we can see that that "whatis (int_t) 0" command
invocation should have printed "type = int_t":

 If @var{arg} is a variable or an expression, @code{whatis} prints its
 literal type as it is used in the source code.  If the type was
 defined using a @code{typedef}, @code{whatis} will @emph{not} print
 the data type underlying the @code{typedef}.
 (...)
 If @var{arg} is a type name that was defined using @code{typedef},
 @code{whatis} @dfn{unrolls} only one level of that @code{typedef}.

That one-level stripping is currently done here, in
gdb/eval.c:evaluate_subexp_standard, handling OP_TYPE:

...
     else if (noside == EVAL_AVOID_SIDE_EFFECTS)
	{
	  struct type *type = exp->elts[pc + 1].type;

	  /* If this is a typedef, then find its immediate target.  We
	     use check_typedef to resolve stubs, but we ignore its
	     result because we do not want to dig past all
	     typedefs.  */
	  check_typedef (type);
	  if (TYPE_CODE (type) == TYPE_CODE_TYPEDEF)
	    type = TYPE_TARGET_TYPE (type);
	  return allocate_value (type);
	}

However, this stripping is reachable in both:

 #1 - (gdb) whatis (int_t)0     # ARG is an expression with a cast to
                                # typedef type.
 #2 - (gdb) whatis int_t        # ARG is a type name.

while only case #2 should strip the typedef.  Removing that code from
evaluate_subexp_standard is part of the fix.  Instead, we make the
"whatis" command implementation itself strip one level of typedefs
when the command argument is a type name.

We then run into another problem, also fixed by this commit:
value_cast always drops any typedefs of the destination type.

With all that fixed, "whatis (int_t) 0" now works as expected:

 (gdb) whatis int_t
 type = int
 (gdb) whatis (int_t)0
 type = int_t

value_cast has many different exit/convertion paths, for handling many
different kinds of casts/conversions, and most of them had to be
tweaked to construct the value of the right "to" type.  The new tests
try to exercise most of it, by trying castin of many different
combinations of types.  With:

 $ make check TESTS="*/whatis-ptype*.exp */gnu_vector.exp */dfp-test.exp"

... due to combinatorial explosion, the testsuite results for the
tests above alone grow like:

 - # of expected passes            246
 + # of expected passes            3811

You'll note that the tests exposed one GCC buglet, filed here:

  Missing DW_AT_type in DW_TAG_typedef of "typedef of typedef of void"
