5ef9273d29 gdbserver: start turning the target ops vector into a class 
This is the beginning of a series of patches where the goal is to turn
the target ops vector into a class and all the target op function
pointers into methods of this class.

Currently, the target ops is a struct of function pointers.  At the
end of the series, it becomes a class with methods, and the existing
low target definitions become subclasses.  That is, we end up with the
following class hierarchy:

  process_stratum_target
  ^
  |-- linux-low
  |-- lynx-low
  |-- nto-low
  |-- win32-low

process_stratum_target either defines the default behavior for the
target ops or leaves them as pure virtual for the subclasses to
override.

The transformation is done by first introducing a helper class, called
'process_target', that is initially empty.  An instance of this class
is added to the end of the current target ops vector.  This new field
is called 'pt'.  We will gradually carry target ops to the new class,
one by one, whereas the invocation of the target op will be converted
to a method call on 'pt'.

For instance, target op 'attach' is currently invoked as

  (*the_target->attach) (args)

After moving 'attach' as a method to 'process_target', it will be
invoked as

  the_target->pt->attach (args)

In this process, the concrete target vector definitions
(e.g. linux-low, win32-low, nto-low, etc.) are turned into derived
classes of 'process_target', so that they can either inherit the
default behavior of the target ops or can override the method.

We prefer to make this transition gradually rather than in a single
giant patch, to yield bite-size patches.  The goal is that after each
patch gdbserver will still be buildable and testable.

The general rule of thumb when converting a target op to a method is
this:

(1) If the function call is protected with a NULL-check with an
obvious default behavior, simply implement that default behavior in
the base class (e.g.: supports_non_stop).

(2) If there is no NULL-check guard, the method becomes pure
virtual, and the derived targets are required to implement the method
(e.g.: attach).

(3) If there is a NULL-check but no apparent default behavior, or if
the NULL-check is utilized to populate a feature support packet,
introduce a 'supports_XYZ' method (e.g.: pid_to_exec_file).

The overall strategy is to preserve the existing behavior as much as
possible.

When we're done moving all the target ops into 'process_target', the
target op vector will contain nothing but the field 'pt'.  At that
point, the auxiliary class 'process_target' will simply meld into
'process_stratum_target' and the method calls of the form
'the_target->pt->xyz' will be turned into 'the_target->xyz'.

The "linux-low" target has been built and reg-tested on X86_64 Linux
(Ubuntu).  The "win32-low" target has been built (but not tested) via
cross-compilation to a x86_64-w64-mingw32 target.  The "lynx-low" and
"nto-low" targets were neither built nor tested.

d13c7322fe gdb: Allow more control over where to find python libraries 
The motivation behind this commit is to make it easier to bundle the
Python *.py library files with GDB when statically linking GDB against
libpython.  The Python files will be manually added into the GDB
installation tree, and GDB should be able to find them at run-time.
The installation tree will look like this:

  .
  |-- bin/
  |-- include/
  |-- lib/
  |   `-- python3.8/
  `-- share/

The benefit here is that the entire installation tree can be bundled
into a single archive and copied to another machine with a different
version of Python installed, and GDB will still work, including its
Python support.

In use the new configure options would be used something like this,
first build and install a static Python library:

  mkdir python
  cd python
  # Clone or download Python into a src/ directory.
  mkdir build
  export PYTHON_INSTALL_PATH=$PWD/install
  cd build
  ../src/configure --disable-shared --prefix=$PYTHON_INSTALL_PATH
  make
  make install

Now build and install GDB:

  mkdir binutils-gdb
  cd binutils-gdb
  # Clone or download GDB into a src/ directory.
  mkdir build
  export GDB_INSTALL_DIR=$PWD/install
  cd build
  ../src/configure \
      --prefix=$GDB_INSTALL_DIR \
      --with-python=$PYTHON_INSTALL_PATH/bin/python3 \
      --with-python-libdir=$GDB_INSTALL_DIR/lib
  make all-gdb
  make install-gdb

Finally, copy the Python libraries into the GDB install:

  cp -r $PYTHON_INSTALL_DIR/lib/python3.8/ $GDB_INSTALL_DIR/lib

After this the Python src, build, and install directories are no
longer needed and can be deleted.

If the new --with-python-libdir option is not used then the existing
behaviour is left unchanged, GDB will look for the Python libraries in
the lib/ directory within the python path.  The concatenation of the
python prefix and the string 'lib/' is now done at configure time,
rather than at run time in GDB as it was previous, however, this was
never something that the user had dynamic control over, so there's no
loss of functionality.

gdb/ChangeLog:

	* config.in: Regenerate.
	* configure: Regenerate.
	* configure.ac: Add --with-python-libdir option.
	* main.c: Use WITH_PYTHON_LIBDIR.

869d89506c Two compute_and_set_names simplifications 
This patch simplifies compute_and_set_names in a couple of ways.

First, it changes one spot to use obstack_strndup, which is
equivalent, but more concise.

Second, the function ends with two calls to symbol_set_demangled_name.
This can be simplified to a single call.

c9c41e6d73 [gdb/testsuite] Fix xpass in gdb.python/lib-types.exp 
When running gdb.python/lib-types.exp, we have an xpass:
...
(gdb) python print (str (typedef_const_typedef_class1_ref_obj.type))^M
typedef_const_typedef_class1_ref^M
(gdb) XPASS: gdb.python/lib-types.exp: \
  python print (str (typedef_const_typedef_class1_ref_obj.type)) \
  (PRMS gcc/55641)
...

When running the same with gcc 4.8, we have an xfail instead:
...
(gdb) python print (str (typedef_const_typedef_class1_ref_obj.type))^M
const typedef_const_typedef_class1_ref^M
(gdb) XFAIL: gdb.python/lib-types.exp: \
  python print (str (typedef_const_typedef_class1_ref_obj.type)) \
  (PRMS gcc/55641)
...

Fix the xpass by xfailing only for the gcc 4.8 pattern.

- gcc 7.5.0
- gcc 4.8.5
- clang 5.0.2

f20ff83737 [gdb/testsuite] Fix funcall_ref.exp xpass 
When running gdb.ada/funcall_ref.exp I run into two XPASSes:
...
(gdb) p get ("Hello world!")^M
$1 = (n => 12, s => "Hello world!")^M
(gdb) XPASS: gdb.ada/funcall_ref.exp: p get ("Hello world!")
ptype get ("Hello world!")^M
type = <ref> record^M
    n: natural;^M
    s: access array (1 .. n) of character;^M
end record^M
(gdb) XPASS: gdb.ada/funcall_ref.exp: ptype get ("Hello world!")
...

The xfails are documented in funcall_ref.exp:
...
 # Currently, GCC describes such functions as returning pointers (instead of
 # references).
 setup_xfail *-*-*
...

Using gnatmake 4.8, we can reproduce the XFAILs:
...
(gdb) p get ("Hello world!")^M
$1 = (access foo.bar) 0x6147b0 <system.secondary_stack.chunk+48>^M
(gdb) XFAIL: gdb.ada/funcall_ref.exp: p get ("Hello world!")
ptype get ("Hello world!")^M
type = access record^M
    n: natural;^M
    s: access array (1 .. n) of character;^M
end record^M
(gdb) XFAIL: gdb.ada/funcall_ref.exp: ptype get ("Hello world!")
...

Fix the XPASSes by:
- removing the xfail setup
- switching the order of the two tests
- detecting the "access record" type and declaring the first test unsupported,
  and skipping the second test

Tested on x86_64-linux, both with gnatmake 4.8.5 and gnatmake 7.5.0.
