9d3cd0c1d4 lib: Put some variable declarations on individual lines
In short, virXXXPtr type is going away. With big bang. And to
help us rewrite the code with a sed script, it's better if each
variable is declared on its own line.

3b5eab6e25 virIndexToDiskName: Make 'idx' unsigned and remove check
We can remove the check that 'idx' is negative by forcing callers to
pass unsigned numbers, which they do already or have a check that 'idx'
is positive.

This in turn allows us to remove most return value NULL checks.

fcea025d0e src: remove use of g_date_time_new_from_iso8601 function
The g_date_time_new_from_iso8601() function was introduced as
a replacement for strptime in

    src: replace strptime()/timegm()/mktime() with GDateTime APIs set

Unfortunately g_date_time_new_from_iso8601 isn't available until
glib 2.56, and backporting it requires alot of code copying and
poking at private glib structs.

This reverts domain_conf.c back to its original parsing logic prior
to 810613a60efe3924c536b3663246900bc08910a5, but using g_date_time_new()
instead of gmtime(). The other files are then adapted to follow a
similar approach.

would be possible to write a new class-creation macro that takes the

b04629b629 conf: Clean up object referencing for Add and Remove
When adding a new object to the domain object list, there should
have been 2 virObjectRef calls made one for each list into which
the object was placed to match the 2 virObjectUnref calls that
would occur during Remove as part of virHashRemoveEntry when
virObjectFreeHashData is called when the element is removed from
the hash table as set up in virDomainObjListNew.

Some drivers (libxl, lxc, qemu, and vz) handled this inconsistency
by calling virObjectRef upon successful return from virDomainObjListAdd
in order to use virDomainObjEndAPI when done with the returned @vm.
While others (bhyve, openvz, test, and vmware) handled this via only
calling virObjectUnlock upon successful return from virDomainObjListAdd.

This patch will "unify" the approach to use virDomainObjEndAPI
for any @vm successfully returned from virDomainObjListAdd.

Because list removal is so tightly coupled with list addition,
this patch fixes the list removal algorithm to return the object
as entered - "locked and reffed".  This way, the callers can then
decide how to uniformly handle add/remove success and failure.
This removes the onus on the caller to "specially handle" the
@vm during removal processing.

The Add/Remove logic allows for some logic simplification such
as in libxl where we can Remove the @vm directly rather than
needing to set a @remove_dom boolean and removing after the
libxlDomainObjEndJob completes as the @vm is locked/reffed.

Now that we have VIR_DOMAIN_CHR_SERIAL_TARGET_TYPE_NONE, we can
