[sdf] Add alloc/free functions. 

* src/sdf/ftsdf.c (*): Add `sdf_alloc' and `sdf_free'
  to allocate and deallocate memory respectively.
  By using function we can directly use them in the
  conditional statements, which is not possible when
  using `do {} while ( 0 )'.

* src/sdf/ftsdf.c (SDF_MEMORY_TRACKER_): When not
  debugging don't leave the macros empty otherwise
  some compiler may emit warning because of empty
  `;' semi-colon.
