We allow the postParse callbacks to fail for some reasons (missing
emulator binary) when parsing the configs from /etc/libvirt.
In that case, def->postParseFailed is set to true and the post
parse callbacks are re-executed on domain startup.
However this bool was only set when virDomainDefPostParse was called
with the ALLOW_POST_PARSE_FAIL flag set. If the callback failed
again on domain startup, the bool would be reset and subsequent
startups would not attempt to reexecute the callback.

There is a pattern of using two temporary utf16/utf8 variables

The check was trying to use the shell variable $CC instead of
the make variable $(CC); it also interpreted grep's return code
wrong: 1 means the provided pattern was *not* matched. As a
result, pdwtags was never run, not even when building with gcc.

Commit id 'edae027c' blindly assumed that the passed @oldDev
parameter would not be NULL when calling virDomainDeviceGetInfo;
however, commit id 'b6a264e8' passed NULL for AttachDevice
callers under the premise that there wouldn't be a device
to check/update against.

When building with CLang the structs that are emitted by pdwtags appear
in a completely different order than with GCC, which causes the
comparison against expected data to fail.
Ideally the test would not be sensitive to the ordering, because even
future GCC could cause changes, but that's not easy to fix. So for now
just skip the test when using clang.

A problem encountered due to a bug in libpcap was reported to the
caller as:
An error occurred, but the cause is unknown
This was because the error had been logged in the DHCPSnoop
thread. The worker thread handling the API call to start a domain
spins up the DHCPSnoop thread which watches for dhcp packets with
libpcap, then uses virCondSignal() to notify the worker thread (which
has been waiting with virCondWait()). The worker thread knows that
there was an error (because threadStatus != THREAD_STATUS_OK), but the
error info had been stored in thread-specific storage for the other
thread, so the worker thread can only report that there was a failure,
but it doesn't know why.
The solution is to save the error that was logged (with
virErrorPreserveLast() into the object the is used to share info
between the threads, then we can set the error in the worker thread
using virErrorRestore().
In the case of the error I was looking at, this changed the "unknown"
message into:
internal error: pcap_setfilter: can't remove kernel filter:
Bad file descriptor

The libvirt_storage_backend_sheepdog_priv.la library depends on symbols
provided in the libvirt_driver_storage_impl.la library. As such the
latter must be listed 2nd when passed to the linker to avoid symbol
resolution problems. This mistake is being masked by the sheepdog
driver linking in a second copy of the storage driver code. Remove
this duplicate linkage of backend source and fix the test link order.
