It would be nice to be able to test the mediated device capabilities
without having physical hardware which supports it. The 'mtty' kernel
module presents a virtual parent device which is capable of creating
'fake' mediated devices, and as such it would be useful for testing.
However, the 'mtty' device is not part of an existing device subsystem
(e.g. PCI, etc), so libvirt ignores it and it does not get added to the
node device list. And because it does not get added to the node device
list, it cannot be used to create child mdevs using `virsh
nodedev-create`.
There is already a node device type capability
VIR_NODE_DEV_CAP_MDEV_TYPES that indicates whether a device supports
creating child mediated devices, but libvirt assumes that this is a
nested capability (in other words, it assumes that the primary
capability of a device is something like PCI). If we allow this
MDEV_TYPES capability to be a primary device capability, then we can
support virtual devices like 'mtty' as a parent for mediated devices.

The updateLock is a R/W lock held by anything which needs to read or
modify the rules associated with an NWFilter.
APIs for defining/undefining NW filters rules hold a write lock on
updateLock.
APIs for creating/deleting NW filter bindings hold a read lock on
updateLock, which prevents define/undefine taking place concurrently.
The problems arise when we attempt to creating two NW filter bindings in
parallel.
Thread 1 can acquire the mutex for filter A
Thread 2 can acquire the mutex for filter B
Consider if filters A and B both reference filters C and D, but in
different orders:
Filter A
-> filter C
-> filter D
Filter B
-> filter D
-> filter C
Thread 1 will try to acquire locks in order A, C, D while thread 1 will
try to acquire in order A, D, C. Deadlock can still occur.
Think we can sort the list of filters before acquiring locks on all of
them ? Nope, we allow arbitrary recursion:
Filter A
-> filter C
-> filter E
-> filter F
-> filter H
-> filter K
-> filter D
-> filter G
-> filter I
So we can't tell from looking at 'A' which filters we're going to
need to lock. We can only see the first level of filters references
and we need to lock those before we can see the second level of
filters, etc.
We could probably come up with some cleverness to address this but
it isn't worth the time investment. It is simpler to just keep the
process of creating NW filter bindings totally serialized.
Using two separate locks for this serialization though is pointless.
Every code path which gets a read(updateLock) will go on to hold
updateMutex. It is simpler to just hold write(updateLock) and
get rid of updateMutex. At that point we don't need updateLock
to be a R/W lock, it can be a plain mutex.
Thus this patch gets rid of the current updateLock and updateMutex
and introduces a new top level updateMutex.
This has a secondary benefit of introducing fairness into the
locking. With a POSIX R/W lock, you get writer starvation if
you have lots of readers. IOW, if we call virNWFilterBIndingCreate
and virNWFilterBindingDelete in a tight loop from a couple of
threads, we can prevent virNWFilterDefine from ever acquiring
a write lock.
Getting rid of the R/W lock gives us FIFO lock acquisition
preventing starvation of any API call servicing.

Every other exported API from virtpm.h will internally call
virTPMEmulatorInit, so there is no reason for this initializer
to be exported on its own.

It is useful to be able to deeply check them for equality.

The functions have very difficult semantics where callers are not able
to tell whether the property is missing or failed the length check. Only
the latter produces errors.
Since usage of the functions was phased out, remove them completely to
avoid further broken code.

This reads and separates all fields from /proc/<pid>/stat or
/proc/<pid>/task/<tid>/stat as there are easy mistakes to be done in the
implementation. Some tests are added to show it works correctly. No number
parsing is done as it would be unused for most of the fields most, if not all,
of the time. No struct is used for the result as the length can vary (new
fields can be added in the future).

With this function we can decide whether to try running the polkit text agent
only if it is available, removing a potential needless error saying that the
agent binary does not exist, which is useful especially when running the agent
before knowing whether it is going to be needed.
