Eric Blake c700613b8d python: use libvirt_util to avoid raw free
This patch starts the process of elevating the python binding code
to be on the same level as the rest of libvirt when it comes to
requiring good coding styles.  Statically linking against the
libvirt_util library makes it much easier to write good code,
rather than having to open-code and reinvent things locally.

Done by global search and replace of s/free(/VIR_FREE(/, followed
by hand-inspection of remaining malloc and redundant memset.

* cfg.mk (exclude_file_name_regexp--sc_prohibit_raw_allocation):
Remove python from exemption.
* python/Makefile.am (INCLUDES): Add gnulib and src/util.  Drop
$(top_builddir)/$(subdir), as automake already guarantees that.
(mylibs, myqemulibs): Pull in libvirt_util and gnulib.
(libvirtmod_la_CFLAGS): Catch compiler warnings if configured to
use -Werror.
* python/typewrappers.c (libvirt_charPtrSizeWrap)
(libvirt_charPtrWrap): Convert free to VIR_FREE.
* python/generator.py (print_function_wrapper): Likewise.
* python/libvirt-override.c: Likewise.

    libvirt Python Bindings README
    ==============================

Most of the libvirt python binding code is automatically generated
using the script  generator.py, and the API description from
docs/libvirt-api.xml


Manually written files:

 - libvirt-override.c: methods where the C binding needs to be hand crafted
 - libvirt-override.py: global methods where the C and python bindings have different args
 - libvirt-override-api.xml: methods where the auto-extracted API docs are not
   suitable for python auto-generator. Overriding this if the method is going
   into libvirt-override.c, but we still want auto-generated libvirt-override.py
 - libvirt-override-virConnect.py: virConnect class methods
 - typewrappers.h,.c: Python object wrappers for each libvirt C object


Auto-generated files:

  - libvirt.py: The main python binding. Comprises auto-generated code, along
    with contents from libvirt-override.py and libvirt-override-virConnect.py
  - libvirt.c, libvirt.h: The C glue layer for the python binding. Comprises
    auto-generated code, along with libvirt-override.c
  - libvirt-export.c: List of auto-generated C methods, included into
    the libvirt-override.c method table
