Change file names in comments to match the files they are in Some of these are leftovers from renaming the files, others are just typos. Also introduce an ugly awk script to enforce this.

Separate internal node device APIs from public API 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. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

Fix virCgroupGetPercpuStats with non-continuous present CPUs 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

virBitmapPtr nodeGetPresentCPUBitmap(void);
cpustat: fix regression when cpus are offline 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.
