Currently, ih_fdclose (which is called by IH_REALLYCLOSE), goes
through every FD_HANDLE_OPEN FdHandle_t and closes it. If it finds
handles that are FD_HANDLE_INUSE, it skips those and sets a flag on
the parent IHandle_t. For non-positional I/O, any future opens cannot
use these _INUSE handles, since _INUSE handles cannot be reused, and
the handle will be actually closed when it is FDH_CLOSE'd.
For positional I/O, the situation is different. Multiple threads can
use the same _INUSE FdHandle_t, and so there is nothing currently
stopping a thread from IH_OPEN'ing an ihandle that has been
IH_REALLYCLOSE'd, and getting back an FdHandle_t that existed before
the IH_REALLYCLOSE was issued. This is important, since IH_REALLYCLOSE
is used on files that are deleted, and future IH_OPENs for the same
inode must not use the cached file descriptor. Getting this wrong can
cause data loss, since it can cause us to read from or write to a file
descriptor referring to a deleted file, when we instead should open a
new copy of that file.
To fix this, we create a new FdHandle_t state called
FD_HANDLE_CLOSING, which is set in IH_REALLYCLOSE if we encounter an
FD_HANDLE_INUSE FdHandle_t. In IH_OPEN, we always skip
FD_HANDLE_CLOSING handles, so we can never get back a cached file
descriptor from before an IH_REALLYCLOSE call.

FdHandle_t's that are on the linked list for an associated IHandle_t
should not be in the state FD_HANDLE_AVAIL. For the non-PIO case, we
assert that this is the case in ih_open (since we assert that if the
FdHandle_t is not in INUSE state, then it must be in OPEN state).
However, for the PIO case, we were just skipping over any FdHandle_t's
that were in the AVAIL state. These should never exist while on that
linked list, so assert for the PIO case, as well.
In the absence of bugs, there is no functional change here, but it
perhaps makes the ih_open loop easier to understand.
