7008e10869 util: Remove virsysfs and instead enhance virFileReadValue* functions
It is no longer needed thanks to the great virfilewrapper.c.  And this
way we don't have to add a new set of functions for each prefixed
path.

While on that, add two functions that weren't there before, string and
scaled integer reading ones.  Also increase the length of the string
being read by one to accompany for the optional newline at the
end (i.e. change INT_STRLEN_BOUND to INT_BUFSIZE_BOUND).

772e42473f virNWFilterObjListFree: Don't leak nwfilters->objs
When adding a nwfilter onto the list in
virNWFilterObjListAssignDef() this array is re-allocated to match
demand for new size. However, it is never freed leading to a
leak:

30e672301d util: rename/move VIR_NET_GENERATED_PREFIX to be consistent
... with VIR_NET_GENERATED_MACV???_PREFIX, which is defined in
util/virnetdevmacvlan.h.

Since VIR_NET_GENERATED_PREFIX is used for plain tap devices, it is
renamed to VIR_NET_GENERATED_TAP_PREFIX and moved to virnetdev.h

9cb891141c conf: don't ignore <target dev='blah'/> for macvtap interfaces
The parser had been clearing out *all* suggested device names for
type='direct' (aka macvtap) interfaces. All of the code implementing
macvtap allows for a user-specified device name, so we should allow
it. In the case that an interface name starts with "macvtap" or
"macvlan" though, we do still clear it out, just as we do with "vnet"
(which is the prefix used for automatically generated tap device
names), since those are the prefixes for the names we autogenerate for
macvtap and macvlan devices.
