These functions initialize @ret to true and only after something
fails either they call cleanup code (which consists only from
virshDomainFree()) and return false, or they set ret = false and
carry on (when the failure occurred close to cleanup code).
Switch them to the usual pattern in which ret is initialized to
failure, goto cleanup is used and ret is set to true only after
everything succeeded.

In my commit of v7.1.0-rc1~376 I've simplified the logic of
handling @flags. My assumption back then was that calling
virDomainSetMemory() is equivalent to
virDomainSetMemoryFlags(flags = 0). But that is not the case,
because it is equivalent to virDomainSetMemoryFlags(flags =
VIR_DOMAIN_AFFECT_LIVE). Fix the condition that calls the old
API.

The current setup uses a single script that is symlinked twice
and that tries to configure bash completion for both virsh and
virt-admin, even if only one of them is installed. This also
forces us to have a -bash-completion RPM package that only
contains the tiny shared file.
Rework bash completion support so that two scripts are
generated, each one tailored to a specific command.
Since the shared script no longer exists after this change,
the corresponding RPM package becomes empty.

Our vsh bash completion string is merely just a wrapper over
virsh/virt-admin complete (cmdComplete) - a hidden command that
uses internal readline completion to generate list of candidates.
But this means that we have to pass some additional arguments to
the helper process: e.g. connection URI and R/O flag.
Candidates are printed on a separate line each (and can contain
space), which means that when bash is reading the helper's output
into an array, it needs to split items on '\n' char - hence the
IFS=$'\n' prefix on the line executing the helper. This was
introduced in b889594a70.
But this introduced a regression - those extra arguments we might
pass are stored in a string and previously were split on a space
character (because $IFS was kept untouched and by default
contains space). But now, after the fix that's no longer the case
and thus virsh/virt-admin sees ' -r -c URI' as one argument.
The solution is to take $IFS out of the picture by storing the
extra arguments in an array instead of string.

virDomainGetDiskErrors uses the weird semantics where we make the
caller query for the number of elements and then pass pre-allocated
structure.
The cleanup section errorneously used the 'count' variable to free the
allocated elements for the API but 'count' can be '-1' in cases when the
API returns failure, thus attempting to free beyond the end of the
array.

Commit 95f8e3237e which introduced XML schema validation
for snapshot XMLs always asserted the validation for the XML generated
by 'virsh snapshot-create-as' on the basis that it's libvirt-generated,
thus valid.
This unfortunately isn't true as users can influence certain bits of the
XML such as the disk image path which must be a full path. Thus if a
user tries to invoke virsh as:
$ virsh snapshot-create-as upstream --diskspec vda,file=relative.qcow2
error: XML document failed to validate against schema: Unable to validate doc against /path/to/domainsnapshot.rng
Extra element disks in interleave
Element domainsnapshot failed to validate content
They get a rather useless error from the libxml2 RNG validator.
With this fix applied, we get to the XML parser in libvirtd which has a
more reasonable error:
$ virsh snapshot-create-as upstream --diskspec vda,file=relative.qcow2
error: XML error: disk snapshot image path 'relative.qcow2' must be absolute
Instead users can force validation of the XML generated by 'virsh
snapshot-create-as' by passing the '--validate' flag.

Historically, we declared pointer type to our types:
typedef struct _virXXX virXXX;
typedef virXXX *virXXXPtr;
But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.
This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:
