[svn-r20052] Description:

    Clean up Coverity warnings, and fix some style issues:

r19735:
Fix for memory leak in test/mf found by valgrind.

r19736:
Fix memory leak in h5repack.  The buffer in copy_objects, when copying the
entire dataset at once, was not checked for the presence of a vlen, and vlen
storage was never reclaimed.  Added check and call to H5D_vlen_reclaim().

r19772:
Change H5assert() to
   if (H5T_VLEN != src->shared->type || H5T_VLEN != dst->shared->type)
          HGOTO_ERROR(H5E_ARGS, H5E_BADTYPE, FAIL, "not a H5T_VLEN datatype")

r19774:
removed unused priv.

r19775:
removed unused variables

r19778:
Fix memory leak comparing for variable length data types.

r19834:
Fixed memory leaks found by valgrind.  Memory errors remain for another day.

Tested on:
    Mac OS X/32 10.6.6 (amazon) w/debug & production
    (h5committested on branch)
