Currently GFortran newer reuses unit numbers allocated with NEWUNIT=,
instead having a simple counter that is decremented each time such a
unit is opened. For a long running program which repeatedly opens
files with NEWUNIT= and closes them, the counter can wrap around and
cause an abort. This patch replaces the counter with an allocator
that keeps track of which units numbers are allocated, and can reuse
them once they have been deallocated. Since operating systems tend to
limit the number of simultaneous open files for a process to a
relatively modest number, a relatively simple approach with a linear
scan through an array suffices. Though as a small optimization there
is a low water indicator keeping track of the index for which all unit
numbers below are already allocated. This linear scan also ensures
that we always allocate the smallest available unit number.
