This partially reverts (and fixes that part in a different way) commit
e4384459, which replaced
``/usr/bin/python'' with ``/usr/bin/env python'' in all examples or
scripts used during build to generate other files.

However, python bindings module is compiled and linked against a
specific python discovered or explicitly provided in configure phase.
Thus libvirt.py, which is generated and installed into the system,
should use the same python binary for which the module has been built.

The hunk in Makefile.am replaces $(srcdir) with $(PYTHON), which might
seem wrong but it is not. generator.py didn't use any of its command
line arguments so passing $(srcdir) to it was redundant.

libvirt.c and libvirt.h are auto-generated files. Mentioning their names
in *_SOURCES includes them in the distribution. During an out-of-tree
build these shipped files are included instead of the auto-generated
version, potentially breaking the build (as it happend in 0.8.0, because
the shipped libvirt.h was missing the declaration for
'libvirt_virDomainUpdateDeviceFlags')

Use the nodist_*_SOURCES automake variable instead.

The latter is not officially "wrong", but *is* terribly anachronistic.
I think automake documentation or comments call that syntax obsolescent.

Commit 66137344 changed the Python detection
mechanism in configure to use AM_PATH_PYTHON. This results in a changed
install location for the Python bindings, at least on Fedora 12 64bit systems.

Before this commit libvirt.py and libvirtmod.so were installed to

  /usr/lib64/python2.6/site-packages

After this commit they are installed to

  /usr/lib/python2.6/site-packages

Mixed Python packages (containing *.py and *.so files) should be installed to
the pyexecdir directory detected by AM_PATH_PYTHON.

This restores the install location from before the AM_PATH_PYTHON commit.

* configure.in: remove unnecessary pythondir export
* python/Makefile.am: switch from pythondir to pyexecdir

Using AM_PATH_PYTHON solves the site-packages directory problem. At least
in Ubuntu with Python 2.6 and later site-packages is renamed to dist-packages
and site-packages is not part of sys.path anymore. So installing the libvirt
Python bindings to site-packages renders them unusable, because they can be
imported from there without manually including site-packages into sys.path.

AM_PATH_PYTHON detects the correct site-packages/dist-packages directory.

python-config --includes gives the correct include path for the Python header
files. The old probing code stays there as fallback mechanism.

* configure.in: use AM_PATH_PYTHON and python-config
* python/Makefile.am: remove -I because PYTHON_INCLUDES contains it now

  virStreamPtr object

  object

  the generator
* typewrappers.c, typewrappers.h: Data type wrappers

  to generated libvirt.py. Output into libvirt.py directly instead of
  libvirtclass.py. Don't generate libvirtclass.txt at all. Write C
  files into libvirt.c/.h directly
* Makefile.am: Remove rule for creating libvirt.py from libvirt-override.py
  and libvirtclass.py, since generator.py does it directly

	* src/remote_internal.c, python/Makefile.am: Python bindings
	  fixed, and now building virConnect.getHostname and

	  libvirt.py from being (re-)built.  Rearranged
	  python/Makefile.am to make it cleaner and clearer.

        * acinclude.m4: add LIBVIRT_COMPILE_WARNINGS, copied from
        GNOME but with a few more flags we'd been using.

        * configure.in: use that instead of setting CFLAGS
        directly.

        * proxy/Makefile.am, python/Makefile.am, qemud/Makefile.am,
          src/Makefile.am, tests/Makefile.am: use $(WARN_CFLAGS)
