Per-cpu stats are only shown for present CPUs in the cgroups,
but we were only parsing the largest CPU number from
/sys/devices/system/cpu/present and looking for stats even for
non-present CPUs.
This resulted in:
internal error: cpuacct parse error

And add stubs to other drivers like: lxc, qemu, uml and vbox.

For future work we want to get info for not only the free memory
but overall memory size too. That's why the function must have
new signature too.

Some of these are leftovers from renaming the files, others
are just typos.

Also introduce an ugly awk script to enforce this.

The individual hypervisor drivers were directly referencing
APIs in src/nodeinfo.c in their virDriverPtr struct. Separate
these methods, so there is always a wrapper in the hypervisor
driver. This allows the unused virConnectPtr args to be
removed from the nodeinfo.c file. Again this will ensure that
ACL checks will only be performed on invocations that are
directly associated with public API usage.

Which is already included by "internal.h", later patch will add
syntax-check to avoid it.

It turns out that the cpuacct results properly account for offline
cpus, and always returns results for every possible cpu, not just
the online ones.  So there is no need to check the map of online
cpus in the first place, merely only a need to know the maximum
possible cpu.  Meanwhile, virNodeGetCPUBitmap had a subtle change
from returning the maximum id to instead returning the width of
the bitmap (one larger than the maximum id) in commit 2f4c5338,
which made this code encounter some off-by-one logic leading to
bad error messages when a cpu was offline:

$ virsh cpu-stats dom
error: Failed to virDomainGetCPUStats()

error: An error occurred, but the cause is unknown

Cleaning this up unraveled a chain of other unused variables.

* src/qemu/qemu_driver.c (qemuDomainGetPercpuStats): Drop
pointless check for cpumap changes, and use correct number of
cpus.  Simplify signature.
(qemuDomainGetCPUStats): Adjust caller.
* src/nodeinfo.h (nodeGetCPUCount): New prototype.
(nodeGetCPUBitmap): Drop unused parameter.
* src/nodeinfo.c (nodeGetCPUBitmap): Likewise.
(nodeGetCPUMap): Adjust caller.
(nodeGetCPUCount): New function.
* src/libvirt_private.syms (nodeinfo.h): Export it.

Added an implemention of virNodeGetCPUMap to nodeinfo.c,
(nodeGetCPUMap) which can be used by all drivers for a Linux
hypervisor host.

Callers should not need to know what the name of the file to
be read in the Linux-specific version of nodeGetCPUmap;
furthermore, qemu cares about online cpus, not present cpus,
when determining which cpus to skip.

While at it, I fixed the fact that we were computing the maximum
online cpu id by doing a slow iteration, when what we really want
to know is the max available cpu.

* src/nodeinfo.h (nodeGetCPUmap): Rename...
(nodeGetCPUBitmap): ...and simplify signature.
* src/nodeinfo.c (linuxParseCPUmax): New function.
(linuxParseCPUmap): Simplify and alter signature.

The compiler might optimize based on our declaration that something
is unused.  Putting that declaration in the header risks getting
out of sync with the actual implementation, so it belongs better
only in the .c files.  We were mostly compliant, and a new syntax
check will help us in the future.

* cfg.mk (sc_avoid_attribute_unused_in_header): New syntax check.
* src/nodeinfo.h (nodeGetCPUStats, nodeGetMemoryStats): Delete
attribute already present in .c file.
* src/qemu/qemu_domain.h (qemuDomainEventFlush): Likewise.
* src/util/virterror_internal.h (virReportErrorHelper): Parameters
are actually used by .c file.
* src/xenxs/xen_sxpr.h (xenFormatSxprDisk): Adjust prototype.

* src/xen/xend_internal.c (xenDaemonAttachDeviceFlags)

Silently ignored flags get in the way of new features that
use those flags.  Also, an upcoming syntax check will favor
unsigned flags.

* src/nodeinfo.h (nodeGetCPUStats, nodeGetMemoryStats): Drop
unused attribute.

* src/util/logging.h (virLogDefineFilter, virLogDefineOutput)

qemudCapsInitNUMA and umlCapsInitNUMA were identical, so this change
factors them into a new function, virCapsInitNUMA, and puts it in
nodeinfo.c.

In addition to factoring out the duplicates, this change also
adjusts that function definition (along with its macros) so
that it works with Fedora 9's numactl version 1, and makes it
so the code will work even if someone builds the kernel with
CONFIG_NR_CPUS > 4096.

Finally, also perform this NUMA initialization for the lxc
and openvz drivers.

* src/nodeinfo.c: Include <stdint.h>, <numa.h> and "memory.h".
(virCapsInitNUMA): Rename from qemudCapsInitNUMA and umlCapsInitNUMA.
(NUMA_MAX_N_CPUS): Define depending on NUMA API version.
(n_bits, MASK_CPU_ISSET): Define, adjust, use uint64 rather than long.
* src/nodeinfo.h: Include "capabilities.h".
(virCapsInitNUMA): Declare it.
* examples/domain-events/events-c/Makefile.am:
* src/Makefile.am: Add $(NUMACTL_CFLAGS) and $(NUMACTL_LIBS) to various
compile/link-related variables.
* src/qemu_conf.c: Include "nodeinfo.h".

* src/lxc_conf.c: Include "nodeinfo.h".
(lxcCapsInit): Perform NUMA initialization here, too.
* src/openvz_conf.c (openvzCapsInit): And here.
Include "nodeinfo.h".
* src/libvirt_sym.version.in: Add virCapsInitNUMA so that libvirtd
can link to this function.

* src/internal.h: move xstrol() variants from here ...

* src/util.[ch]: ... to here and rename to virStrToLong()

* src/libvirt_sym.version: export __virStrToLong_i() for
virsh and qemud.

* src/nodeinfo.c, src/stats_linux.c, src/virsh.c,
  src/xend_internal.c, qemud/qemud.c: replace xstrtol()
calls with virStrToLong()

* src/nodeinfo.h: don't include internal.h, which was only
needed for xstrtol(), but instead include libvirt.h which
is suffificient for the declarations in the header.
