Log message:
	do not use python<version> subdir when including Python .h file
	
	This is preparation work for being able to build GDB with Python
	support on MinGW.
	
	So far, the "python<version>" subdirectory needs to be specified
	when including a Python header file.  In order to do that, we have
	some special configury that tweaks the include path returned by
	python-config.py such that the use of the subdirectory in the include
	is necessary.  This was done in order to protect ourselves from
	possible filename conflicts, since some of the filenames chosen by
	Python were a little generic.
	
	The problem is that this cannot work with a standard Python install
	on MinGW systems.  On such systems, the .h files are located in
	<python_prefix>/include.  So, in preparation for allowing us to build
	GDB on MinGW with Python support enabled, this patch changes the
	requirement to provide the "python<version>" subdirectory in the
	include directive.
	
	The positive consequence is that we no longer need to have a set
	of #include directives for each version of Python, since the include
	directive is now the same for all versions of Python.  However, the
	downside is that we are losing the level of protection we were trying
	to achieve by forcing the subdirectory in the include directive.
	In order to reduce a bit the consequences of a possible conflict,
	this patch also changes the location where the -I/path/to/python
	switch goes, to be last in the list (suggested by Doug Evans).
	
	One last change is the fact that we are now including Python.h
	and all other Python include headers using angle brackets rather
	than double-quotes.  This fixes a problem on case-insensitive
	systems where #include "Python.h" causes our gdb/python/python.h
	header to be included instead of Python's <Python.h> header.
	
	gdb/ChangeLog:
	
	* configure.ac: Remove fallback behavior for building
	against Python.  Remove tweaking of Python include path.
	Add PYTHON_CPPFLAGS and PYTHON_LIBS substitution.
	(AC_TRY_LIBPYTHON):  Adjust program used in linking test.
	If link is successful, set PYTHON_CPPFLAGS and PYTHON_LIBS.
	Always restore CPPFLAGS and LIBS after linking test.
	* configure: Regenerated.
	* Makefile.in (INTERNAL_CPPFLAGS): Add @PYTHON_CPPFLAGS@.
	(INSTALLED_LIBS, CLIBS): Add @PYTHON_LIBS@.
	* python/python-internal.h: Adjust includes of Python .h files.
