Bug 11336: (follow-up) improve POD for _FixPriority()

Browse source 
This patch improves the POD for C4::Reserves::_FixPriority()
to (hopefully) describe its function thoroughly.  It also
adjusts the call of _FixPriority() by CancelReserve() to
omit passing reserve_id, since by that point no row in
the reserves table for that request still exists.

Only used internally (so don't export it)
Changed how this functions works #
Now just gets an array of reserves in the rank order and updates them with
the array index (+1 as array starts from 0)
and if $rank is supplied will splice item from the array and splice it back in again
in new priority rank
or
=cut
_FixPriority({ biblionumber => $biblionumber});
This routine adjusts the priority of a hold request and holds
on the same bib.
In the first form, where a reserve_id is passed, the priority of the
hold is set to supplied rank, and other holds for that bib are adjusted
accordingly. If the rank is "del", the hold is cancelled. If no rank
is supplied, all of the holds on that bib have their priority adjusted
as if the second form had been used.
In the second form, where a biblionumber is passed, the holds on that
bib (that are not captured) are sorted in order of increasing priority,
then have reserves.priority set so that the first non-captured hold
has its priority set to 1, the second non-captured hold has its priority
set to 2, and so forth.
In both cases, holds that have the lowestPriority flag on are have their
priority adjusted to ensure that they remain at the end of the line.
Note that the ignoreSetLowestRank parameter is meant to be used only
when _FixPriority calls itself.
