Commit c9c03ea stopped creating an intermediate file during syntax-check
to save on execution time. It also switched to outputting the whole
incorrectly wrapped file instead of a diff needed to fix it.
Feed the newly wrapped file to diff via a pipe.
Note that fixing it by running test-wrap-argv.pl --in-place or
the unit test with VIR_TEST_REGENERATE_OUTPUT is easier.
Commit 843a70a changed test-wrap-argv.pl to use
/usr/bin/env perl
instead of
/usr/bin/perl
However when called from qemuxml2argvtest with
VIR_TEST_REGENERATE_OUTPUT, PATH is set to '/bin'.
Find the path to perl early in virTestMain, in case we
are going to need it later after we've overridden PATH.
In commit ec5dcf2a and b0b4a35c we have moved qemuhotplugtest's XMLs to
new directories but forgot to fix the Makefile. Add 2 directories in
EXTRA_DIST to fix broken VPATH build. Also remove now unused
qemuhotplugtestdata directory from the Makefile as well as from the
tree.

The libvirtdconftest was previously used to test data type
handling of the libvirtd config file. Now we're using the
typedef APIs, this test case has little value, and is pretty
hard to fixup with deal with the new APIs.

Currently many users of virConf APIs are defining the same
macros for calling virConfValue() and then doing type
checking. To remove this repeated code, add a set of
typesafe accessor methods.

If the config file does not end with a \n, the parser will append
one. When re-allocating the array though, it is mistakenly assuming
that 'len' is the length including the trailing NUL, but it does
not. So we must add 2 to len, when reallocating, not 1.

The virconftest is different from all our other tests in that
the C program only tests a single in/out config file pair. It
relies on a shell wrapper to invoke it once for each test
file.
This gets rid of the shell wrapper and makes the C program
actually run over each test file using the normal test pattern.

This way we can safely differentiate what XMLs contain whole domain
definitions and which contain just devices. Thanks to that we can
test the domain XMLs in virschematest again.

This makes the search for related XMLs easier, plus they are not used in
the xml2argv tests anyway. This also makes future patches cleaner.
While on that remove unnecessary '-hotplug' from the filenames.

In the mock, we have a stub for virNetDevTapCreate(). However,
the mocked version does not exactly as it's native counterpart.
The function receives a string, which is an interface name that
caller would like to have, but it's not guaranteed that they will
get just that one. If they don't, the function free()-s the one
passed and returns the new one. Just like the mocked version. But
what is the mocked version missing is the free().

This one's a bit more complicated. In qemuProcessPrepareDomain()
a master key for encrypting secret for ciphered disks is created.
This object lives within qemuDomainObjPrivate object. It is freed
in qemuProcessStop(), but if nobody calls it (for instance like
our qemuxml2argvtest does), the key object leaks.

Just like every other qemuBuild*CommandLine() function, this uses
a buffer to hold partial cmd line strings too. However, if
there's an error, the control jumps to 'cleanup' label leaving
the buffer behind and thus leaking it.

Setting up cgroups and other things for all kinds of threads (the
emulator thread, vCPU threads, I/O threads) was copy-pasted every time
new thing was added. Over time each one of those functions changed a
bit differently. So create one function that does all that setup and
start using it, starting with I/O thread setup. That will shave some
duplicated code and maybe fix some bugs as well.

It was further performing two distinct error checks in
the same conditional and reporting a single error message,
which was misleading in one of the two cases.
This splits the conditional check into two parts with
distinct error messages and fixes the logic error.

qemu: Store vCPU thread ids in vcpu private data objects
Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
An error in virHostCPUGetKVMMaxVCPUs() means we've been unable
to access /dev/kvm, or we're running on a platform that doesn't
support KVM in the first place.
If that's the case, we shouldn't ignore the error and report
domcapabilities even though we know the user won't be able to
start any KVM guest.
If we don't HAVE_LINUX_KVM_H, we can't query /dev/kvm to discover
the limits on the number of vCPUs, so we report an error and
return a negative value instead.
Allow to store driver specific data on a per-vcpu basis.
Move of the virDomainDef*Vcpus* functions was necessary as
virDomainXMLOptionPtr was declared below this block and I didn't want to
split the function headers.
Status XML tests were done by prepending a constant string to an
existing XML. With the planned changes the header will depend on data
present in the definition rather than just on the data that was parsed.
The first dynamic element in the header will be the vcpu thread list.
Reuse and rename qemuXML2XMLPreFormatCallback for gathering the relevant
data when checking the active XML parsing and formating and pass the
bitmap to a newly crated header generator.
Most callers make sure that it's never called with an out of range vCPU.
Every other caller reports a different error explicitly. Drop the error
reporting and clean up some dead code paths.
The new function works as expected, and matches the current level of
autocomplete offered, along with several other improvements like quotes
handling, multiple command completion and space handling. Now, it is easy
to introduce options completer here.

A bool 'report' has been introduced in various functions, which when set
to true will produce the error it is suppposed to produce, and when
false, will suppress the error. These functions are used in the next
patch for auto-completion.
