[MOAB-dev] [PATCH 1/2] iMesh_MOAB: do not allocate new memory for count=0 items

[Jed Brown]

It is relatively common to fill a buffer with consecutive queries, some
of which may return zero items.  In such scenarios, the user passes in a
valid pointer, but occasionally a length of 0.  In such scenarios,
having the library allocate a new buffer of zero length is not
desirable.

On the other hand, if a user knowingly passes in a length of zero, but
undefined pointer value, they would expect the library to return a
pointer that can safely be passed to free().  A workaround is to nullify
the pointer prior to calling iMesh with expectation of a new array.
