Replace the switch statement with a simpler if statement. This also

5431055d2b util: Force reading of meta data to get encryption capacity value
https://bugzilla.redhat.com/show_bug.cgi?id=1371892

As it turns out the volume create, build, and refresh path was not peeking
at the meta data, so immediately after a create operation the value displayed
for capacity was still incorrect. However, if a pool refresh was done the
correct value was fetched as a result of a meta data peek.

The reason is it seems historically if the file type is RAW then peeking
at the file just took the physical value for the capacity. However, since
we know if it's an encrypted file, then peeking at the meta data will be
required in order to get a true capacity value.

So check for encryption in the source and if present, use the meta data
in order to fill in the capacity value and set the payload_offset.

edaf135657 virNetDevOpenvswitchInterfaceStats: Be more forgiving when fetching stats
https://bugzilla.redhat.com/show_bug.cgi?id=1461270

When fetching stats for a vhost-user type of interface, we run
couple of ovs-vsctl commands and parse their output. However, not
all stats exist at all times, for instance "rx_dropped" or
"tx_errors" can be missing. Thing is, we ask for a bulk of
statistics and if one of them is missing an error is reported
instead of returning the rest. Since we ignore errors, we fail to
set statistics. Fix this by asking for each piece alone.

This commit fixes a locale problem with locales that use comma as a mantissa
separator. Example: 12.34 en_US = 12,34 pt_BR. Since strtod() is a non-safe
function, virStrToDouble() will have problems to parse double numbers from
kernel settings and other double numbers from static files (XMLs, JSONs, etc).

5004f121bc virFDStreamThread: Make sure we won't exceed @length
There's a problem with current streams after I switched them from
iohelper to thread implementation. Previously, iohelper made sure
not to exceed specified @length resulting in the pipe EOF
appearing at the exact right moment (the pipe was used to tunnel
the data from the iohelper to the daemon). Anyway, when switching
to thread I had to write the I/O code from scratch. Whilst doing
that I took an inspiration from the iohelper code, but since the
usage of pipe switched to slightly different meaning, there was
no 1:1 relationship between the codes.

Moreover, after introducing VIR_FDSTREAM_MSG_TYPE_HOLE, the
condition that should made sure we won't exceed @length was
completely wrong.

The fix is to:

a) account for holes for @length
b) cap not just data sections but holes too (if @length would be
exceeded)

For this purpose, the condition needs to be brought closer to the
code that handles holes and data sections.

Basically, what is needed here is to introduce new message type
for the messages passed between the event loop callbacks and the
worker thread that does all the I/O. The idea is that instead of
a queue of read buffers we will have a queue where "hole of size
X" messages appear. That way the event loop callbacks can just
check the head of the queue and see if the worker thread is in
data or a hole section and how long the section is.

07c2399c01 virfdstream: Use messages instead of pipe
One big downside of using the pipe to transfer the data is that
we can really transfer just bare data. No metadata can be carried
through unless some formatted messages are introduced. That would
be quite painful to achieve so let's use a message queue. It's
fairly easy to exchange info between threads now that iohelper is
no longer used.

The reason why we cannot use the FD for plain files directly is
that despite us setting noblock flag on the FD, any
read()/write() blocks regardless (which is a show stopper since
those parts of the code are run from the event loop) and poll()
reports such FD as always readable/writable - even though the
subsequent operation might block.

The pipe is still not gone though. It is used to signal the event
loop that an event occurred (e.g. data is available for reading
in the queue, or vice versa).
