3020f550ca tests: Prepare for subcore tests
The nodeGetThreadsPerSubcore() function is mocked to return 8 for
ppc64 tests, which corresponds to the default subcore mode.

Update the expected output for the deconfigured-cpus nodeinfo
test to account for this change.

75f6f54546 nodeinfo: Make sysfs_prefix usage more consistent
Make sure sysfs_prefix, when present, is always the first argument
to a function; don't use a different name to refer to it; check
whether it is NULL, and hence SYSFS_SYSTEM_PATH should be used, only
when using it directly and not just passing it down to another
function; always pass down the same value we've been passed when
calling another function.

f8b784a8ef tests: Add nodeinfo test for non-present CPUs
Some of the possible CPUs in a system might not be present, eg. they
might be defective or might have been deconfigured from the ASM console
in a Power system. Due to this fact, Linux keeps track of what CPUs are
possible and what are present separately.

This test uses the data from a system where not all the possible CPUs
are present to make sure libvirt handles this situation correctly.

f4dc812c9e virNodeParseSocket: Take ARM into account
The virNodeParseSocket() function tries to get socked ID from
'topology/physical_package_id' file. However, on some architectures
the file contains the -1 constant which makes in turn libvirt think
the info extraction was unsuccessful. If that's the case, we need to
overwrite the obtained integer with zero like we are doing for other
architectures.

df80282dab tests: reduce length of nodeinfodata test names
Commit ddd6bef4 switched to the ustar format to fix an issue where
'make dist' fails to create a tarball because we have files with
relative names longer than 100 bytes by the time you include a
'libvirt-0.9.13' prefix.  Unfortunately, even with ustar format,
the use of 'tar -ch' tries to convert symlinks to hard links,
also with a name too long (omitting the -h works, but automake
automatically passes -h); such symlinks were added in commit
6dcf98c, which resulted in 'make dist' breaking again.  The
solution is to rename the offending symlinks to something shorter,
by shortening the entire nodeinfodata naming scheme.

* tests/nodeinfotest.c (mymain): Shorten test names.
(linuxTestNodeInfo): Accommodate new names.
* tests/nodeinfodata/*: Rename files accordingly.

03e0ec10b4 nodeinfo: deal with offline cpus in a node
Commit 80533ca forgot to think about offline cpus.  When a node
cpu is offline, then its topology/ subdirectory is not present,
leading to spurious error messages leaked to the user such as:

libvir:  error : cannot open /home/dummy/libvirt/tests/nodeinfodata/linux-nodeinfo-sysfs-test-6/node/node0/cpu7/topology/physical_package_id: No such file or directory

Fix that, as well as test it; the test data is gathered from a
machine with one NUMA node, hyperthreading, and with 2 of the
8 cpus offline.

* src/nodeinfo.c (virNodeParseNode): Don't parse topology of
offline cpus.
* tests/nodeinfotest.c (mymain): Run new test.
* tests/nodeinfodata/linux-nodeinfo-sysfs-test-6*: New data.

2b366b46dc nodeinfo: avoid probing host filesystem during test
We had previously weakened our nodeinfotest in order to ignore parsed
node values, because the parse function was mistakenly relying on
host files.  A better fix is to avoid using the numactl library, but
to instead parse the same files that numactl would read, all while
allowing the files to be relative to our choice of directory.

* src/nodeinfo.c (CPU_SYS_PATH, NODE_SYS_PATH): Replace with...
(SYSFS_SYSTEM_PATH): ...parent directory.
(linuxNodeInfoCPUPopulate): Check NUMA nodes from requested
directory (by inlining numactl code).
(nodeGetCPUmap, nodeGetMemoryStats): Adjust macro use.
* tests/nodeinfotest.c (linuxTestCompareFiles, linuxTestNodeInfo):

9943276fd2 Cleanup for a return statement in source files
Return statements with parameter enclosed in parentheses were modified
and parentheses were removed. The whole change was scripted, here is how:

List of files was obtained using this command:
git grep -l -e '\<return\s*([^()]*\(([^()]*)[^()]*\)*)\s*;' |             \
grep -e '\.[ch]$' -e '\.py$'

Found files were modified with this command:
sed -i -e                                                                 \
's_^\(.*\<return\)\s*(\(\([^()]*([^()]*)[^()]*\)*\))\s*\(;.*$\)_\1 \2\4_' \
-e 's_^\(.*\<return\)\s*(\([^()]*\))\s*\(;.*$\)_\1 \2\3_'

Then checked for nonsense.

The whole command looks like this:
git grep -l -e '\<return\s*([^()]*\(([^()]*)[^()]*\)*)\s*;' |             \
grep -e '\.[ch]$' -e '\.py$' | xargs sed -i -e                            \
's_^\(.*\<return\)\s*(\(\([^()]*([^()]*)[^()]*\)*\))\s*\(;.*$\)_\1 \2\4_' \
-e 's_^\(.*\<return\)\s*(\([^()]*\))\s*\(;.*$\)_\1 \2\3_'

7b7cb1ecc9 deprecate fclose() and introduce VIR_{FORCE_}FCLOSE()
Similarly to deprecating close(), I am now deprecating fclose() and
introduce VIR_FORCE_FCLOSE() and VIR_FCLOSE(). Also, fdopen() is replaced with
VIR_FDOPEN().

Most of the files are opened in read-only mode, so usage of
VIR_FORCE_CLOSE() seemed appropriate. Others that are opened in write
mode already had the fclose()<  0 check and I converted those to
VIR_FCLOSE()<  0.

I did not find occurrences of possible double-closed files on the way.
