Commit cd48c3f4 added a Py_ssize_t typedef for Python < 2.7.
But Py_ssize_t was added in Python 2.5. This makes the build fail
for Python 2.6.

Adjust the check to match Python < 2.5 to fix this.

I'm not sure when Py_ssize_t was introduced; but Fedora 14 Python 2.7
has it, while RHEL 5 Python 2.4 lacks it.  It should be easy enough
to adjust if someone runs into problems.

* python/typewrappers.h (Py_ssize_t): Define for older python.

The return values for the python version are different that the C version
of virStreamSend: on success we return a string, an error raises an exception,
and if the stream would block we return int(-2). We need to do this
since strings aren't passed by reference in python.

v2:
    Don't generate virStreamFree

I have primarily followed the pattern of the 'secret' driver to provide
support for the missing python bindings for the network filter API.

Introduce a new public API that provides a way to get progress
info on currently running jobs on a virDomainpPtr. APIs that
are initially within scope of this idea are

 virDomainMigrate
 virDomainMigrateToURI
 virDomainSave
 virDomainRestore
 virDomainCoreDump

These all take a potentially long time and benefit from monitoring.
The virDomainJobInfo struct allows for various pieces of information
to be reported

 - Percentage completion
 - Time
 - Overall data
 - Guest memory data
 - Guest disk/file data

* include/libvirt/libvirt.h.in: Add virDomainGetJobInfo
* python/generator.py, python/libvirt-override-api.xml,
  python/libvirt-override.c: Override for virDomainGetJobInfo API
* python/typewrappers.c, python/typewrappers.h: Introduce wrapper
  for unsigned long long type

* include/libvirt/libvirt.h.in: Public API contract for
  virStreamPtr object
* src/libvirt_public.syms: Export data stream APIs
* src/libvirt_private.syms: Export internal helper APIs
* src/libvirt.c: Data stream API driver dispatch
* src/datatypes.h, src/datatypes.c: Internal helpers for virStreamPtr
  object
* src/driver.h: Define internal driver API for streams
* .x-sc_avoid_write: Ignore src/libvirt.c because it trips
  up on comments including write()
* python/Makefile.am: Add libvirt-override-virStream.py
* python/generator.py: Add rules for virStreamPtr class
* python/typewrappers.h, python/typewrappers.c: Wrapper
  for virStreamPtr
* docs/libvirt-api.xml, docs/libvirt-refs.xml: Regenerate
  with new APIs

* README: New file describing what each file is used for
* livvirt-override.c, libvirt-override.py, libvirt-override-api.xml,
  libvirt-override-virConnect.py: Manually written code overriding
  the generator
* typewrappers.c, typewrappers.h: Data type wrappers
* generator.py: Automatically pre-prend contents of libvirt-override.py
  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

Sample session:

>>> import libvirt
>>> c = libvirt.open('qemu:///session')

>>> c.listSecrets()
['12247729-47d2-a783-88ce-b329d4781cd3', 'reee', 'abc']

>>> s = c.secretDefineXML("<secret ephemeral='no' private='no'>\n<description>Something for use</description>\n<volume>/foo/bar</volume>\n</secret>\n")

>>> s.UUIDString()
'340c2dfb-811b-eda8-da9e-25ccd7bfd650'

>>> s.XMLDesc()
"<secret ephemeral='no' private='no'>\n  <uuid>340c2dfb-811b-eda8-da9e-25ccd7bfd650</uuid>\n  <description>Something for use</description>\n  <volume>/foo/bar</volume>\n</secret>\n"

>>> s.setValue('abc\0xx\xffx')
0

>>> s.value()
'abc\x00xx\xffx'

>>> s.undefine()
0

* python/generator.py: Add rules for virSecret APIs
* python/libvir.c, python/libvirt-python-api.xml: Manual impl of
  virSecretSetValue, virSecretGetValue$ and virConnectListSecrets APIs

  Re-generate with 'make api'

by running this command:
git ls-files -z | xargs -0 perl -pi -0777 -e 's/\n\n+$/\n/'
This is in preparation for a more strict make syntax-check
rule that will detect trailing blank lines.

  python/libvir.py python/libvirt_wrap.h python/types.c:
  adds support for events from the python bindings, also
  improves the generator allowing to embbed per function
  definition files, patch by Ben Guthro
* examples/domain-events/events-python/event-test.py: also
  adds a programming example

Done using this command (also includes .c.in and .h.in files):

        Change #include <> to #include "" for local includes.
        Removed many includes from src/internal.h and put them in
        the C files which actually use them.
        Removed <ansidecl.h> - unused.
        Added a comment around __func__.
        Removed a clashing redefinition of VERSION symbol.
        All limits (PATH_MAX etc) now done in src/internal.h, so we
        don't need to include those headers in other files.

  avoid using "" in the includes themselves.
Daniel

  the Perl bindings, regenerated
* python/libvirt_wrap.h: added a missing include.
Daniel

  the specs, the icons, the docs, etc ...
* configure.in: prepare for 0.0.3
Daniel

  missing features like list of domains and domain info extraction
Daniel

  version for python bindings, heavilly based on libxml2/libxslt
  way of doing things, maybe this need to be revisited. Added packaging
  too.
* src/hash.h: fixed the Copyright notice.
