Since its introduction in v1.3.2-43-gef1fa55e46 there is a dead
code in virDomainCgroupSetupGlobalCpuCgroup() (well,
qemuSetupGlobalCpuCgroup() back then). The code formats NUMA
nodeset but never sets it.

The virDomainCgroupSetupVcpuBW() is a NOP if both period and

Instead of reporting virReportError(..., g_strerror(), ...) let's
use proper virReportSystemError(). Generated with help of cocci:
@@
expression c;
@@
<...
- virReportError(c,
+ virReportSystemError(errno,
...,
- g_strerror(errno),
...);

But then I had to hand fix format strings, because I'm not sure
if cocci even knows how to do that. And even if it did, I surely
don't.

Note that we attempt to remove logs only if virtlogd is in use.
Otherwise we do not know the pattern for rotated files.
For example for VM named "foo" we can not use "foo.log*" pattern to
remove rotated logs as we can have VM named "foo.log" with log
"foo.log.log". We can add extra check that filename does not end with
".log" but for VM "foo.log" we can have rotated log "foo.log.log.1". Ok
let's check we don't have "log" in filename part corresponging to * but
what if someone will use logrotate with "%Y.log-%m-%d" 'dateformat'
option. In this case the check will exclude proper rotated files.
Yes, the last example if quite artificial but it shows it is difficult
to find out correctly rotated files when rotated files pattern is not
known. Thus the above decision only to support case with virtlogd when
we know the pattern.
Another reason for not removing log files when logrotate is present is
that due to races some files can escape deletion. For example foo.log.3
will be rotated to foo.log.4 after removing function will read directory
files and thus foo.log.4 will not be deleted.

virNetworkForwardDef.managed is a bool but
virNetworkPortDef.hostdevpci.managed is a virTristateBool, which
means that the current code performs the following incorrect
conversion:
false -> BOOL_ABSENT
true -> BOOL_YES
Using the virTristateBoolFromBool() helper solves the issue.
