120465f38a m4: Fix check for yajl.pc
Commit 44b8df4cb4 introduced a check for yajl.pc that is
extremely similar to the one we already had in place for
readline.pc - so similar, in fact, that it's still looking
for readline.pc instead of yajl.pc :)

b5ee13e329 tests: fix mocking of virFileGetXAttrQuiet on FreeBSD
The qemusecuritytest is failing on FreeBSD 11/12, reporting that files
are not correctly restored. Debugging code printfs show that the
virFileGetXAttrQuiet mock is returning 0, but the virFileGetXAttr
function is seeing -1 as the return value.

Essentially there appears to be some kind of optimization between the
real virFileGetXAttrQuiet and the real virFileGetXAttr, which breaks
when we mock virFileGetXAttrQuiet. Rather than trying to figure out
how to avoid this, it is simpler to just mock virFileGetXAttr too
since it is very short code.

8b1660e530 security: Don't remember owner for shared resources
This effectively reverts d7420430ce and adds new code.

Here is the problem: Imagine a file X that is to be shared
between two domains as a disk. Let the first domain (vm1) have
seclabel remembering turned on and the other (vm2) has it turned
off. Assume that both domains will run under the same user, but
the original owner of X is different (i.e. trying to access X
without relabelling leads to EPERM).

Let's start vm1 first. This will cause X to be relabelled and to
gain new attributes:

  trusted.libvirt.security.ref_dac="1"
  trusted.libvirt.security.dac="$originalOwner"

When vm2 is started, X will again be relabelled, but since the
new label is the same as X already has (because of vm1) nothing
changes and vm1 and vm2 can access X just fine. Note that no
XATTR is changed (especially the refcounter keeps its value of 1)
because the vm2 domain has the feature turned off.

Now, vm1 is shut off and vm2 continues running. In seclabel
restore process we would get to X and since its refcounter is 1
we would restore the $originalOwner on it. But this is unsafe to
do because vm2 is still using X (remember the assumption that
$originalOwner and vm2's seclabel are distinct?).

The problem is that refcounter stored in XATTRs doesn't reflect
the actual times a resource is in use. Since I don't see any easy
way around it let's just not store original owner on shared
resources. Shared resource in world of domain disks is:

  - whole backing chain but the top layer,
  - read only disk (we don't require CDROM to be explicitly
    marked as shareable),
  - disk marked as shareable.

377b4e0a6b security_dac: Allow caller to suppress owner remembering
One caller in particular (virSecurityDACSetImageLabelInternal)
will want to have the feature turned on only in some cases.
Introduce @remember member to _virSecurityDACChownItem to track
whether caller wants to do owner remembering or not.
The actual remembering is then enabled if both caller wanted it
and the feature is turned on in the config file.

Technically, we could skip over paths that don't have remember
enabled when creating a list of paths to lock. We won't touch
their XATTRs after all. Well, I rather play it safe and keep them
on the locking list for now.

5214b2f1a3 security: Don't skip label restore on file systems lacking XATTRs
The way that virSecurityDACRecallLabel is currently written is
that if XATTRs are not supported for given path to the caller
this is not different than if the path is still in use. The value
of 1 is returned which makes secdrivers skip label restore.
This is clearly a bug as we are not restoring labels on say NFS
even though previously we were.

Strictly speaking, changes to virSecurityDACRememberLabel are not
needed, but they are done anyway so that getter and setter behave
in the same fashion.
