The macro is huge and gives us nothing but headache when maintaining it.

A couple of functions were declared using the old style foo()
for no-parameters, instead of foo(void)

* src/xen/xen_hypervisor.c, tests/testutils.c: Replace () with (void)
  in some function declarations
* m4/virt-compile-warnings.m4: Enable -Wold-style-definition

* src/internal.h: Define a ATTRIBUTE_NO_RETURN annotation
* src/lxc/lxc_container.c: Annotate lxcContainerDummyChild
  with ATTRIBUTE_NO_RETURN
* tests/eventtest.c: Mark async thread as ATTRIBUTE_NO_RETURN
* m4/virt-compile-warnings.m4: Enable -Wmissing-noreturn

Add a couple of missing ATTRIBUTE_FMT_PRINTF annotations

* tools/virsh.c, tests/testutils.c: Add printf format attribute
* m4/virt-compile-warnings.m4: Enable -Wmissing-format-attribute

Split the bit acinclude.m4 file into smaller pieces named
as m4/virt-XXXXX.m4

* .gitignore: Ignore gettext related files
* acinclude.m4: Delete
* m4/virt-compile-warnings.m4: Checks for GCC compiler flags
* m4/virt-pkgconfig-back-compat.m4: Backcompat check for
  pkgconfig program

Remove custom code for checking compiler warnings, using
gl_WARN_ADD instead. Don't list all flags ourselves, use
gnulib's gl_MANYWARN_ALL_GCC to get all possible GCC flags,
then turn off the ones we don't want yet.

* acinclude.m4: Rewrite to use gl_WARN_ADD and gl_MANYWARN_ALL_GCC
* bootstrap.conf: Add warnings & manywarnings
* configure.ac: Switch to gl_WARN_ADD
* m4/compiler-flags.m4: Obsoleted by gl_WARN_ADD

* src/openvz/openvz_driver.c: Initialize saveptr variable

Removes 4kb stack allocation in the XenD subdriver.

Replace openvz_readline with getline in several places to get rid of stack
allocated buffers to hold lines.

openvzReadConfigParam allocates memory for return values instead of
expecting a preexisting buffer.

Removes multiple 4kb stack allocations.

Removes TODO comments as suggested by Daniel P. Berrange.

Move the buffers to the heap allocated client/private data structs.

Removing a 4kb stack allocation.

Reduce stack buffer for virStrerror to the common 1kb instead of 4kb.

Allocate on the heap instead.

Use virAsprintf instead of snprintf.

Make virFileBuildPath operate on the heap instead of the stack. It
allocates a buffer instead of expecting a preexisting buffer.

The domainSetAutostart function is nearly identical to the one from qemu.

This patch enables the relative backing file path support provided by
qemu-img create.

If a relative path is specified for the backing file, it is converted
to an absolute path using the storage pool path. The absolute path is
used to verify that the backing file exists. If the backing file exists,
the relative path is allowed and will be provided to qemu-img create.

Even with -Wuninitialized (which is part of autobuild.sh
--enable-compile-warnings=error), gcc does NOT catch this
use of an uninitialized variable:

{
  if (cond)
    goto error;
  int a = 1;
error:
  printf("%d", a);
}

which prints 0 (supposing the stack started life wiped) if
cond was true.  Clang will catch it, but we don't use clang
as often.  Using gcc -Wjump-misses-init catches it, but also
gives false positives:

{
  if (cond)
    goto error;
  int a = 1;
  return a;
error:
  return 0;
}

Here, a was never used in the scope of the error block, so
declaring it after goto is technically fine (and clang agrees).
However, given that our HACKING already documents a preference
to C89 decl-before-statement, the false positive warning is
enough of a prod to comply with HACKING.

[Personally, I'd _really_ rather use C99 decl-after-statement
to minimize scope, but until gcc can efficiently and reliably
catch scoping and uninitialized usage bugs, I'll settle with
the compromise of enforcing a coding standard that happens to
reject false positives if it can also detect real bugs.]

If strdup("x509dname") or strdup("saslUsername") success, but
strdup(x509dname) or strdup(saslUsername) failed, subject->nidentity
is not the num elements of subject->identities, and we will leak some
memory.

There is no need to lock vm while allocating memory. If allocating
memory failed, we forgot to unlock vm.

  When you happen to have a libvirtd binary compiled with the
libxenlight driver (say you have installed xen-4.1 libraries)
but not running a xen enabled system, then libvirtd fails to start.

The cause is that libxlStartup() returns -1 when failing to initialize
the library, and this propagates to virStateInitialize() which consider
this a failure. We should only exit libxlStartup with an error code
if something like an allocation error occurs, not if the driver failed
to initialize.

* src/libxl/libxl_driver.c: fix libxlStartup() to not return -1
  when failing to initialize the libxenlight library

Commit 78ba748e claims to fix
documentation for swap_hard_limit virsh memtune option but it only fixes
documentation in formatdomain.html and libvirt.h. This patch completes
the task by fixing "virsh help memtune" output and memtune section of
virsh man page.

as needed on non linux ports using HAL.

qemu driver uses a 4K buffer for reading qemu log file. This is enough
when only qemu's output is present in the log file. However, when
debugging messages are turned on, intermediate libvirt process fills the
log with a bunch of debugging messages before it executes qemu binary.
In such a case the buffer may become too small. However, we are not
really interested in libvirt messages so they can be filtered out from
the buffer.
