RX files were including the same header set in three different places,
once for user-land builds, once for kernel builds and once for ukernel.
The duplication was a bit pointless, and really frustrating when adding
new headers. So, reorganise the includes so that we only list headers
that are used in all three builds in one location.
Also take the opportunity to indent the #ifdefs so that it is clear
what is going on, and to remove some more of AFS_OSF_ENV and
AFS_AUX_ENV from kernel builds.

In VScheduleSalvage_r, we were calling VCancelReservation_r, which has
the possibility of free'ing vp. Since we still use vp after doing this
(and since we're already inside VCancelReservation_r to begin with),
we must not free vp. Instead, just decrement nWaiters without
triggering any of the dtor code in VCancelReservation_r. This is safe
as long as all VScheduleSalvage_r callers ensure that they check to
free the vp if necessary, which they all do.

Currently, when an error is encountered for an attached volume, we
call VRequestSalvage_r, which makes the volume go into the
VOL_STATE_SALVAGING state. This state implies that the volume is
offline, however, which is not necessarily the case if we're calling
VRequestSalvage_r from, for example, VAllocVnode_r or VUpdateVolume_r.
So now, make a new state called VOL_STATE_SALVAGE_REQ to indicate when
a salvage has been requested but the volume is not offline yet (and
thus is not yet ready to give to the salvager). If VCheckSalvage finds
a volume in this state, it offlines the volume first. The FSSYNC
VOL_OFF handler now checks for this state, and if we're giving the
volume to the salvager, we wait for the volume to exit that state.
VRequestSalvage_r also gains a new flag, VOL_SALVAGE_NO_OFFLINE. This
is to ensure that the existing salvaging code paths for unattached
volumes does not change (for when VRequesetSalvage_r is called from
attach2). If this flag is passed, we do what we used to do, which is
just salvage the volume without offlining it.

Additionally, correct the locking around vgone(). The
vnode lock must be held, and we must also increase the vnode's
hold count so that it does not disappear out from under us.
As we need the interlock to check the usecount, keep it
locked until we lock the vnode lock, for extra protection.
As an added bonus, we no longer try to call vgonel(), which
