The platform check which determines when to apply the fixups mentions
all officially supported build targets (per docs/platforms.rst) thus
it's not really necessary.
Additionally while not explicitly written as supported the check does
not work properly when building with the MinGW toolchain on Windows as
it does not apply the needed transformations. They are necessary
there the same way as with MinGW on Linux.

set useBinarySpecificLabel = true when calling qemuSecurityCommandRun
for the passt process, so that the new process context will include
the binary-specific label that should be used for passt (passt_t)
rather than svirt_t (as would happen if useBinarySpecificLabel was
false). (The MCS part of the label, which is common to all child
processes related to a particular qemu domain instance, is also set).

Normally when a child process is started by libvirt, the SELinux label
of that process is set to virtd_t (plus an MCS range). In at least one
case (passt) we need for the SELinux label of a child process label to
match the label that the binary would have transitioned to
automatically if it had been run standalone (in the case of passt,
that label is passt_t).
This patch modifies virSecuritySELinuxSetChildProcessLabel() (and all
the functions above it in the call chain) so that the toplevel
function can set a new argument "useBinarySpecificLabel" to true. If
it is true, then virSecuritySELinuxSetChildProcessLabel() will call
the new function virSecuritySELinuxContextSetFromFile(), which uses
the selinux library function security_compute_create() to determine
what would be the label of the new process if it had been run
standalone (rather than being run by libvirt) - the MCS range from the
normally-used label is added to this newly derived label, and that is
what is used for the new process rather than whatever is in the
domain's security label (which will usually be virtd_t).
In order to easily verify that nothing was broken by these changes to
the call chain, all callers currently set useBinarySpecificPath =
false, so all behavior should be completely unchanged. (The next
patch will set it to true only for the case of running passt.)

The binary to be exec'ed by virExec() is stored in

Since we will have another use for the full absolute path, lets make
an API to resolve/retrieve the absolute path, and cache it in
virCommand::binaryPath so we only have to do the resolution once.

Commit 54fa1b44af ("conf: Add loadparm boot option for a boot device")
added the ability to specify a loadparm parameter on a <boot/> tag, while
commit 29ba41c2d4 ("qemu: Add loadparm to qemu command line string")
added that value to the QEMU "-machine" command line parameters.
Unfortunately, the latter commit only looked at disks and network
devices for boot information, even though anything with
VIR_DOMAIN_DEF_FORMAT_ALLOW_BOOT could potentially have this tag.
In practice, a <hostdev> tag pointing to a passthrough (SCSI or DASD)
disk device can be used in this way, which means the loadparm is
accepted, but not given to QEMU.
Correct this, and add some XML/argv tests.
