If there are two paths on the list that are the same we need to
lock it only once. Because when we try to lock it the second time
then open() fails. And if it didn't, locking it the second time
would fail for sure. After all, it is sufficient to lock all
paths just once satisfy the caller.

When spawning a child process, between fork() and exec() we close
all file descriptors and keep only those the caller wants us to
pass onto the child. The problem is how we do that. Currently, we
get the limit of opened files and then iterate through each one
of them and either close() it or make it survive exec(). This
approach is suboptimal (although, not that much in default
configurations where the limit is pretty low - 1024). We have
/proc where we can learn what FDs we hold open and thus we can
selectively close only those.

Ideally, a software that's translating domain names would iterate
over all addresses the NSS returned, but some software does not
bother (e.g. ping). What happens is that for instance when
installing a guest, it's assigned one IP address but once it's
installed and rebooted it gets a different IP address (because
client ID used for the first DHCP traffic when installing the
guest was generated dynamically and never saved so after reboot
the guest generated new ID which resulted in different IP address
to be assigned). This results in 'ping $domain' not working
properly as it still pings the old IP address. Well, it might -
NSS plugin does not guarantee any order of addresses.
To resolve this problem, we can sort the array just before
returning it to the caller (ping) so that the newer IP addresses
come before older ones.

In the nss plugin we have ERROR() macro which by default does
nothing. However, at compile time it can be made to report errors
(this is useful for debugging because by nature of NSS debugging
is hard). Anyway, the appendAddr() function uses @name (which
contains name the caller wants us to resolve) for error
reporting. But the caller findLeaseInJSON() is not passing it.

When validating a domain among all the checks there are two that
concern VIR_DOMAIN_LOADER_TYPE_PFLASH specifically. The first
check ensures that on x86 ACPI is enabled when UEFI is requested,
the second ensures that UEFI is used when ACPI is requested on
aarch64. However, check for UEFI is done by plain comparison of
def->os.loader->type which is insufficient because we have
def->os.firmware too.
NB, this wouldn't be a problem for active domain, because on
startup process def->os.loader->type gets filled by
qemuFirmwareEnableFeatures(), but that's not the case for
inactive domains.

Split up the addition of a storage source into the following sub-steps:
1) storage access dependencies (TLS transport, persistent reservation)
2) storage acccess node (file/gluster/nbd...)
3) format driver dependencies (encryption secret)
4) format driver node (qcow2, raw, ...)
The functions split out will be later reused when implementing support
for 'blockdev-create' as we'll need the dependencies plugged in first,
then blockdev-create will be called and after that successfully finishes
blockdev-add will be added.

qemuMonitorDriveMirror requires the unmodified state of the flags to
pass to qemu and also we use the value a few times internally. Extract
it separately now.
The 'reuse' flag did not indicate reusing of the file as much as the
fact that the storage is existing and thus should not be created, so
modify the name to reflect this.

source) disk.
