    gfapi: warn when glfs_realpath() returned malloc'd memory

    glfs_realpath() may return memory allocated with malloc(). Depending on
    the memory allocator that the application uses, calling free() on the
    returned string can cause segmentation faults or other problems.

    Functions that allocate memory, need to match the free'ing of the same
    memory allocator and memory accounting. glibc/malloc and jemalloc/free
    do not match together (other allocators could probably trigger these
    problems as well).

    Applications need to provide a pre-allocated buffer, or in case
    glfs_realpath() allocates the memory, glfs_free() should be used to free
    it.
