Various fixes for C and C++ compiling. 

* src/autofit/*: Add copyright messages.
  Formatting.

* src/autofit/afhints.c (af_glyph_hints_done): Don't use
`AF_Dimension' but `int' for loop counter.

* src/autofit/aflatin.c (af_latin_metrics_init_widths): Don't use
`AF_Dimension' but `int' for loop counter.
Use proper enumeration value for `render_mode'.
(af_latin_metrics_scale_dim): Don't shadow variables.
(af_latin_hints_compute_segments): Use proper cast for `major_dir'
and `segment_dir'.
(af_latin_align_linked_edge, af_latin_hint_edges): Fix arguments of call to
`af_latin_compute_stem_width'.
(af_latin_hints_apply): Don't use `AF_Dimension' but `int' for loop
counter.

* src/base/ftdbgmem.c (ft_mem_table_get_source, FT_DumpMemory): Use
proper cast for memory allocation.

* src/cff/cffdrivr.c (cff_get_kerning): Use proper cast for
initialization of `sfnt'.

* src/sfnt/sfdriver.c: Include `ttkern.h'.

* src/sfnt/ttkern.c (tt_face_get_kerning): Don't shadow variables.

* src/truetype/ttgload.c: Include `ttpload.h'.

* src/truetype/ttpload.c (tt_face_load_loca) [FT_OPTIMIZE_MEMORY]:
Remove redundant variable.
