0258d9ab46 cmdNetworkList: switch to FILTER
Instead of sticking to old code pattern use the one laid out by

variables.

Move all the system_* fields into a separate struct. Not only this
simplifies the code a bit it also helps us to identify whether BIOS
info is present. We don't have to check all the four variables for
being not-NULL, but we can just check the pointer to the struct.

7971723b98 qemu: Add capability for vhost-user multiqueue
The support for this was added in QEMU with commit
830d70db692e374b55555f4407f96a1ceefdcc97.  Unfortunately we have to do
another ugly version-based capability check.  The other option would be
not to check for the capability at all and leave that to qemu as it's
done with multiqueue tap devices.

d587704cc7 rpc: allow selection of TCP address family
By default, getaddrinfo() will return addresses for both
IPv4 and IPv6 if both protocols are enabled, and so the
RPC code will listen/connect to both protocols too. There
may be cases where it is desirable to restrict this to
just one of the two protocols, so add an 'int family'
parameter to all the TCP related APIs.

1c24cfe9d8 virNumaSetPagePoolSize: Produce friendlier error message
https://bugzilla.redhat.com/show_bug.cgi?id=1224587

The function takes two important arguments (among many others): @node
and @page_size. From these two a path under /sys is constructed. The
path is then used to read and write the desired size of huge pages
pool. However, if the path does not exists due to either @node or
@page_size having nonexistent value (e.g. there's no such NUMA node or
no page size like -2), an cryptic error message is produced:

  virsh # allocpages --pagesize 2049 --pagecount 8 --cellno -2
  error: Failed to open file '/sys/devices/system/node/node-2/hugepages/hugepages-2049kB/nr_hugepages': No such file or directory

Add two more checks to catch this and therefore produce much more
friendlier error messages.

489c81c00c parallels: add block device statistics to driver
Statistics provided through PCS SDK. As we have only async interface in SDK we
need to be subscribed to statistics in order to get it. Trivial solution on
every stat request to subscribe, wait event and then unsubscribe will lead to
significant delays in case of a number of successive requests, as the event
will be delivered on next PCS server notify cycle. On the other hand we don't
want to keep unnesessary subscribtion. So we take an hibrid solution to
subcsribe on first request and then keep a subscription while requests are
active. We populate cache of statistics on subscribtion events and use this
cache to serve libvirts requests.

 * Cache details.
Cache is just handle to last arrived event, we call this cache
as if this handle is valid it is used to serve synchronous
statistics requests. We use number of successive events count
to detect that user lost interest to statistics. We reset this
count to 0 on every request. If more than PARALLELS_STATISTICS_DROP_COUNT
successive events arrive we unsubscribe. Special value of -1
of this counter is used to differentiate between subscribed/unsubscribed state
to protect from delayed events.

Values of PARALLELS_STATISTICS_DROP_COUNT and PARALLELS_STATISTICS_TIMEOUT are
just drop-ins, choosen without special consideration.

 * Thread safety issues
Use parallelsDomObjFromDomainRef in parallelsDomainBlockStats as
we could wait on domain lock down on stack in prlsdkGetStatsParam
and if we won't keep reference we could get dangling pointer
on return from wait.

65a0b334f9 parallels: return only success from PCS event handler
2 reasons to to this.
1. PCS SDK really don't care of handler return value.
2. It hard to imagine how notifier can handle
subscriber failures. Even if there are some situations
we probably will use some special error codes and
not just throw error codes we get from SDK itself.

ceb46a662d utiltest: Use int8_t instead of char.
Not every architecture out there has 'char' signed by default.
For instance, my arm box has it unsigned by default:

  $ gcc -dM -E - < /dev/null | grep __CHAR_UNSIGNED__
  #define __CHAR_UNSIGNED__ 1

Therefore, after 65c61e50 the test if failing for me. Problem is,
we are trying to assign couple of negative values into char
assuming some will overflow and some don't. That can't be the
case if 'char' is unsigned by default. Lets use more explicit types
instead: int8_t and uint8_t where is no ambiguity.
