064e24bc1e lvmdbusd: Only read whats buffered
When reading data from stdout & stderr we were reading until the
reading until we got None back which really isn't needed as the
read will return everything that is available.

8a4dfe6ce7 cleanup: use lv_update_and_reload
Avoid code duplication and use exiting commonly used
lv_update_and_reload() function.

There is still one place left where mirror is doing strange
double suspend call - needs there more thinking what's wrong with
that code.

0ad95b77d0 mirror: preserve MIRRORED status for temporara image
When lvconvert adds a new leg - it's doing it free 'temporary' image
layer - however this temporary 'internal' mirror is also MIRRORED LV.

df92d330aa lvmdbusd: Extra report FD read on no data
Our expectation was that when using the lvm shell that when the lvm prompt
was read from stdout, that all other ouput had been written and flushed.
However, this doesn't appear to be the case.  Add extra read passes to
retrieve delayed report data.

61f6be7d2b lvmdbustest.py: Reduce test client introspection calls
The default dbus python library mode of operation is to leverage
introspection.  However, this introspection data isn't accessible
for users of the library and they have to specifically retrieve
the introspection data too. This resulted in many introspection
calls being made.  This change eliminates introspection calls if
we are testing multiple concurrent test clients.  If it's a single
client we will leverage a reduced amount of introspection data to
verify the introspection data is correct.  Typically clients don't
leverage introspection data nearly as much as this test client.

cd28717f24 lvmdbustest.py: Support concurrent test runs
The env variable LVM_DBUSD_PV_DEVICE_LIST when present and filled in
with at least 4 physical devices will run concurrently with other
instances running as long as they specify different devices in their
env variable.

When the env variable is not present the test runs as it did before.

fa444906bb lvmdbusd: Use one thread to fetch state updates
In preparation to have more than one thread issuing commands to lvm
at the same time we need to serialize updates to the dbus state and
retrieving the global lvm state.  To achieve this we have one thread
handling this with a thread safe queue taking and coalescing requests.

2a86f54b09 libdm: separate dm_stats_populate() error cases
There are two possible errors in _dm_stats_populate_region():

  * No region struct in dms->regions[region_id]
  * Failure to parse data from @stats_print

These have very different causes: the first occurs where a client
program is populating one region at a time (region_id is a single
region identifier), and has not previously called dm_stats_list()
to dimension the region tables; this is an API usage error.

The second occurs when either we read unparseable data from the
kernel (kernel bug), or where various resource allocations fail.

Separate these two cases out and log separate messages for each
(allocation failures in the path already have their own distinct
message), since the "failed to parse.." message in the un-listed
handle case is confusing and misleading.

68d6d342f8 dbus: only log msg as debug if lvm2-lvmdbusd unit missing for D-Bus notification
Do not emit warning message but only log debug message if
lvm2-lvmdbusd.service unit is missing and at the same time
we have global/notify_dbus=1 (which is used by default if we
configured sources with "--enable-notify-dbus"). We don't want
hard dependency between LVM2 and lvmdbusd so it's enough to log
only debug message in this case.

4a2250f9ce tests: update make targets
Add  new targets:

make check_lvmpolld
make check_cluster_lvmpolld
make check_lvmetad_lvmpolld
make check_all_lvmpolld

So check_lvmetad runs only base lvmetad test - to much
logic of remaining targets.

Previous behavior is available via  check_all_lvmpolld.

d8fc4d093e conf: support zero for missing_stripe_filler
Make it easier to replace missing segments with 'zero' returning
target - otherwise user would have to create some extra target
to provide zeros as /dev/zero can't be used (not a block device).

Also break code loop when segment is found and make it an INTERNAL_ERROR
where it's missing.
