* python/libvir.c, python/libvirt_wrap.h, qemud/qemud.c,
        qemud/remote.c, src/internal.h, src/openvz_conf.c,
        src/openvz_driver.c, src/proxy_internal.h, src/qemu_conf.c,
        src/qemu_driver.c, src/remote_internal.h, src/test.h, src/util.c,
        src/xen_unified.c, src/xen_unified.h, tests/nodeinfotest.c,
        tests/qemuxml2argvtest.c, tests/qemuxml2xmltest.c, tests/reconnect.c,
        tests/sexpr2xmltest.c, tests/virshtest.c, tests/xencapstest.c,
        tests/xmconfigtest.c, tests/xml2sexprtest.c:
        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.

* if (x) LIBVIRT_STMT_START { ... } LIBVIRT_STMT_END; else ...
*
* When GCC is compiling C code in non-ANSI mode, it will use the
* compiler __extension__ to wrap the statements wihin `({' and '})' braces.
* When compiling on platforms where configure has defined
* HAVE_DOWHILE_MACROS, statements will be wrapped with `do' and `while (0)'.
* For any other platforms (SunOS4 is known to have this issue), wrap the
* statements with `if (1)' and `else (void) 0'.
