When an error is expected, the error message will be checked.
This is expressed by creating an additional ".err" file containing
the expected error message.
It is added in order to make sure the expected errors
are not masked by other errors during test execution while
leveraging the existing framework.
In order to keep it simple, an input file cannot be reused
anymore to cover several expected error cases configured
in the test code. An input file can still be reused by creating
a test case specific symlink.
For consistency, the mock needs to report an error now, too,
as every failure must have an error; otherwise a test case will
fail.
Require LC_ALL=C explicitly to make sure error messages are not

The XML format used for QEMU capabilities is not required to be
stable across releases, as we invalidate the cache whenever the
libvirt binary changes.
We none the less always try to parse te entire XML file before
we do any validity checks. Thus if we change the format of any
part of the data, or change permitted values for enums, then
libvirtd logs will be spammed with errors.
These are not in fact errors, but an expected scenario.
This change makes the loading code validate the cache timestamp
against the libvirtd timestamp immediately. If they don't match
then we stop loading the rest of the XML file.

Turns out that it's not enough to pass the qemu:///embed root to
virQEMUDriverConfigNew(), you also have to make sure the same
string is copied into the virQEMUDriver structure yourself, and
not doing so in our case resulted in the cleanup never happening
and in distcheck failing because of that.
On the other hand, actually setting config->embeddedRoot would
result in different paths being generated for each test run, which
would obviously break qemuxml2argvtest, so that's not an option
either.

The virQEMUDriverConfigNew() accepts path to root directory for
embed mode as an argument. If the argument is not NULL it uses
the passed value as prefix for some internal paths (e.g.
cfg->libDir). If it is NULL though, it looks if the other
argument, @privileged is true or false and generates internal
paths accordingly. But when calling the function from the test
suite, instead of passing NULL for @root, an empty string is
passed. Fortunately, this doesn't create a problem because in
both problematic cases the generated paths are "fixed" to point
somewhere into build dir or the code which is tested doesn't
access them.

This enables support for running QEMU embedded to the calling
application process using a URI:
qemu:///embed?root=/some/path
Note that it is important to keep the path reasonably short to
avoid risk of hitting the limit on UNIX socket path names
which is 108 characters.
When using the embedded mode with a root=/var/tmp/embed, the
driver will use the following paths:
logDir: /var/tmp/embed/log/qemu
swtpmLogDir: /var/tmp/embed/log/swtpm
configBaseDir: /var/tmp/embed/etc/qemu
stateDir: /var/tmp/embed/run/qemu
swtpmStateDir: /var/tmp/embed/run/swtpm
cacheDir: /var/tmp/embed/cache/qemu
libDir: /var/tmp/embed/lib/qemu
swtpmStorageDir: /var/tmp/embed/lib/swtpm
defaultTLSx509certdir: /var/tmp/embed/etc/pki/qemu
These are identical whether the embedded driver is privileged
or unprivileged.
This compares with the system instance which uses
logDir: /var/log/libvirt/qemu
swtpmLogDir: /var/log/swtpm/libvirt/qemu
configBaseDir: /etc/libvirt/qemu
stateDir: /run/libvirt/qemu
swtpmStateDir: /run/libvirt/qemu/swtpm
cacheDir: /var/cache/libvirt/qemu
libDir: /var/lib/libvirt/qemu
swtpmStorageDir: /var/lib/libvirt/swtpm
defaultTLSx509certdir: /etc/pki/qemu
At this time all features present in the QEMU driver are available when
running in embedded mode, availability matching whether the embedded
driver is privileged or unprivileged.
