Create an array of modules to be built to allow for flexibility to
enable or disable some modules in the future and allow for additional
modules to be added easily
Since we don't always want to build all the modules, and there might be
more modules added in the future but we want to retain backwards
compatibility with older libvirts, change generator.py to be called once
per module instead of with all modules at once.
The generated libvirt.py modules will be in the build/
directory, so santitytest.py must use that directory.

virTypedParamsClear() and virTypedParamsFree() were introduced in
libvirt 1.0.2. In an effort to keep the code clean bring these two
functions to libvirt-python if we're building against a version of
libvirt that's older than 1.0.2
Add LIBVIR_CHECK_VERSION from libvirt upstream so that we can check the
version of the library we are compiling against and support a range of
libvirt versions. The macro was added to libvirt in 1.2.0 so we must
provide it if its not defined.
Import the libvirt memory allocation functions, stripping the OOM
testing and error reporting pieces.

We're no longer using automake, so <config.h> files are not
required. Also remove of all libvirt internal util header
files. Reference generated header files in build/ subdir.

This reverts commit 6b90d7428d72e92db292a9228c44701bfd5003c9.
The original problem was that libvirt_virConnectGetCPUModelNames
was listed twice in the exports table, once automatically from
the generator and once from the manual override. We merely needed
to list it in the skip_impl list, and not delete the manually
written code entirely.
Commit de51dc9c9aed0e615c8b301cccb89f4859324eb0 primarily added
virConnectGetCPUModelNames as libvirt.getCPUModelNames(conn, arch)
instead of libvirt.virConnect.getCPUModelNames(arch) so revert the code
that does the former while leaving the code that does the later.
This is the rest of the patch that was ACK'd by Dan but I committed only
the partial patch in 6a8b8ae.

fix the remaining uses before adding a syntax check.

Commit d76227be added functions virDomainCreateWithFiles and
virDomainCreateXMLWithFiles, but there was a little piece missing in
python bindings. This patch fixes proper passing of file descriptors
in the overwrites of these functions.
The libvirt.so library has far too many library deps to allow
linking against it from setuid programs. Those libraries can
do stuff in __attribute__((constructor) functions which is
not setuid safe.
The virt-login-shell needs to link directly against individual
files that it uses, with all library deps turned off except
for libxml2 and libselinux.
Create a libvirt-setuid-rpc-client.la library which is linked
to by virt-login-shell. A config-post.h file allows this library
to disable all external deps except libselinux and libxml2.

'const fooPtr' is the same as 'foo * const' (the pointer won't
change, but it's contents can). But in general, if an interface
is trying to be const-correct, it should be using 'const foo *'
(the pointer is to data that can't be changed).
Fix up offenders in the python bindings.
* python/generator.py (py_types): Drop useless conversions.
* python/libvirt-override.c (getPyVirTypedParameter)
(setPyVirTypedParameter): Use intended type.

The memory size in virNodeGetInfo python API binding is reported in MiB
instead of KiB (like we have in C struct). However, there already might
be applications out there relying on this inconsistence so we can't
simply fix it. Document this sad fact as known bug.
The new function virConnectGetCPUModelNames allows to retrieve the list
of CPU models known by the hypervisor for a specific architecture.

Automake has builtin support to prevent botched conditional nesting,
but only if you use:
if FOO
else !FOO
endif !FOO
An example error message when using the wrong name:
daemon/Makefile.am:378: error: else reminder (LIBVIRT_INIT_SCRIPT_SYSTEMD_TRUE) incompatible with current conditional: LIBVIRT_INIT_SCRIPT_SYSTEMD_FALSE
daemon/Makefile.am:381: error: endif reminder (LIBVIRT_INIT_SCRIPT_SYSTEMD_TRUE) incompatible with current conditional: LIBVIRT_INIT_SCRIPT_SYSTEMD_FALSE
As our makefiles tend to have quite a bit of nested conditionals,
it's better to take advantage of the benefits of the build system
double-checking that our conditionals are well-nested, but that
requires a syntax check to enforce our usage style.
Alas, unlike C preprocessor and spec files, we can't use indentation
to make it easier to see how deeply nesting goes.
* cfg.mk (sc_makefile_conditionals): New rule.

Consistently use "is" or "is not" to compare variables to None,
because doing so is preferrable, as per PEP 8
(http://www.python.org/dev/peps/pep-0008/#programming-recommendations):
> Comparisons to singletons like None should always be done with is or
> is not, never the equality operators.
The python/tests directory contains a number of so called
"tests" for the python API. These are all hardcoded to
look for Xen and cannot be run in any automated fashion,
and no one is ever manually running them. Given that they
don't meaningully contribute to the test coverage, delete
them.
For some reason these tests were also copied into the
filesystem as part of 'make install'. The change to the
RPM in commit 3347a4203278ec93d7b0ceb88b5ed10e4f14765c
caused a build failure, since it removed the code which
deleted these installed tests.

File hasn't been really touched for 7 years. And with recent rawhide
changes it contributed to an RPM build failure. Let's drop it.
This also removes installation of a libvirt-python doc dir, so drop
handling of it from the RPM spec.
Makefiles are another easy file to enforce line limits.
Mostly straightforward; interesting tricks worth noting:
src/Makefile.am: $(confdir) was already defined, use it in more places
tests/Makefile.am: path_add and VG required some interesting compression
* cfg.mk (sc_prohibit_long_lines): Add another test.
* Makefile.am: Fix offenders.
* daemon/Makefile.am: Likewise.
* docs/Makefile.am: Likewise.
* python/Makefile.am: Likewise.
* src/Makefile.am: Likewise.
* tests/Makefile.am: Likewise.

With container based virt, it is useful to be able to pass
pre-opened file descriptors to the container init process.
This allows for containers to be auto-activated from incoming
socket connections, passing the active socket into the container.
To do this, introduce a pair of new APIs, virDomainCreateXMLWithFiles
and virDomainCreateWithFiles, which accept an array of file
descriptors. For the LXC driver, UNIX file descriptor passing
will be used to send them to libvirtd, which will them pass
them down to libvirt_lxc, which will then pass them to the container
init process.
This will only be implemented for LXC right now, but the design
is generic enough it could work with other hypervisors, hence
I suggest adding this to libvirt.so, rather than libvirt-lxc.so

Currently, when there is no blockjob, dom.blockJobInfo('vda')
still reports error because it doesn't distinguish return value 0 from -1.
libvirt.libvirtError: virDomainGetBlockJobInfo() failed
virDomainGetBlockJobInfo() API return value:
-1 in case of failure, 0 when nothing found, 1 found.
And use PyDict_SetItemString instead of PyDict_SetItem when key is
of string type. PyDict_SetItemString increments key/value reference
count, so call Py_DECREF() for value. For key, we don't need to
do this, because PyDict_SetItemString will handle it internally.
Convert the type of loop iterators named 'i', 'j', k',
'ii', 'jj', 'kk', to be 'size_t' instead of 'int' or
'unsigned int', also santizing 'ii', 'jj', 'kk' to use
the normal 'i', 'j', 'k' naming

This patch introduces two new APIs virDomainMigrate3 and
virDomainMigrateToURI3 that may be used in place of their older
variants. These new APIs take optional migration parameters (such as
bandwidth, domain XML, ...) in an array of virTypedParameters, which
makes adding new parameters easier as there's no need to introduce new
APIs whenever a new migration parameter needs to be added. Both APIs are
backward compatible and will automatically use older migration calls in
case the new calls are not supported as long as the typed parameters
array does not contain any parameter which was not supported by the
older calls.
